NAME Firefox::Marionette - Automate the Firefox browser with the Marionette protocol VERSION Version 1.31 SYNOPSIS use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/'); say $firefox->find_tag('title')->property('innerHTML'); # same as $firefox->title(); say $firefox->html(); $firefox->find_class('page-content')->find_id('metacpan_search-input')->type('Test::More'); say "Height of page-content div is " . $firefox->find_class('page-content')->css('height'); my $file_handle = $firefox->selfie(); $firefox->await(sub { $firefox->find_class('autocomplete-suggestion'); })->click(); $firefox->find_partial('Download')->click(); DESCRIPTION This is a client module to automate the Mozilla Firefox browser via the Marionette protocol SUBROUTINES/METHODS accept_alert accepts a currently displayed modal message box accept_connections Enables or disables accepting new socket connections. By calling this method with false the server will not accept any further connections, but existing connections will not be forcible closed. Use true to re-enable accepting connections. Please note that when closing the connection via the client you can end-up in a non-recoverable state if it hasn't been enabled before. active_element returns the active element of the current browsing context's document element, if the document element is non-null. add_certificate accepts a hash as a parameter and adds the specified certificate to the Firefox database with the supplied or default trust. Allowed keys are below; * path - a file system path to a single PEM encoded X.509 certificate . * string - a string containing a single PEM encoded X.509 certificate * trust - This is the trustargs value for NSS . If defaults to 'C,,'; This method returns itself to aid in chaining methods. use Firefox::Marionette(); my $pem_encoded_string = <<'_PEM_'; -----BEGIN CERTIFICATE----- MII.. -----END CERTIFICATE----- _PEM_ my $firefox = Firefox::Marionette->new()->add_certificate(string => $pem_encoded_string); add_cookie accepts a single cookie object as the first parameter and adds it to the current cookie jar. This method returns itself to aid in chaining methods. This method throws an exception if you try to add a cookie for a different domain than the current document . add_header accepts a hash of HTTP headers to include in every future HTTP Request. use Firefox::Marionette(); use UUID(); my $firefox = Firefox::Marionette->new(); my $uuid = UUID::uuid(); $firefox->add_header( 'Track-my-automated-tests' => $uuid ); $firefox->go('https://metacpan.org/'); these headers are added to any existing headers. To clear headers, see the delete_header method use Firefox::Marionette(); my $firefox = Firefox::Marionette->new()->delete_header( 'Accept' )->add_header( 'Accept' => 'text/perl' )->go('https://metacpan.org/'); will only send out an Accept header that looks like Accept: text/perl. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new()->add_header( 'Accept' => 'text/perl' )->go('https://metacpan.org/'); by itself, will send out an Accept header that may resemble Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8, text/perl. This method returns itself to aid in chaining methods. add_login accepts a hash of the following keys; * host - The scheme + hostname of the page where the login applies, for example 'https://www.example.org'. * user - The username for the login. * password - The password for the login. * origin - The scheme + hostname that the form-based login was submitted to . Forms with no action attribute default to submitting to the URL of the page containing the login form, so that is stored here. This field should be omitted (it will be set to undef) for http auth type authentications and "" means to match against any form action. * realm - The HTTP Realm for which the login was requested. When an HTTP server sends a 401 result, the WWW-Authenticate header includes a realm. See RFC 2617 . If the realm is not specified, or it was blank, the hostname is used instead. For HTML form logins, this field should not be specified. * user_field - The name attribute for the username input in a form. Non-form logins should not specify this field. * password_field - The name attribute for the password input in a form. Non-form logins should not specify this field. or a Firefox::Marionette::Login object as the first parameter and adds the login to the Firefox login database. use Firefox::Marionette(); use UUID(); my $firefox = Firefox::Marionette->new(); # for http auth logins my $http_auth_login = Firefox::Marionette::Login->new(host => 'https://pause.perl.org', user => 'AUSER', password => 'qwerty', realm => 'PAUSE'); $firefox->add_login($http_auth_login); $firefox->go('https://pause.perl.org/pause/authenquery')->accept_alert(); # this goes to the page and submits the http auth popup # for form based login my $form_login = Firefox::Marionette::Login(host => 'https://github.com', user => 'me2@example.org', password => 'uiop[]', user_field => 'login', password_field => 'password'); $firefox->add_login($form_login); # or just directly $firefox->add_login(host => 'https://github.com', user => 'me2@example.org', password => 'uiop[]', user_field => 'login', password_field => 'password'); This method returns itself to aid in chaining methods. add_site_header accepts a host name and a hash of HTTP headers to include in every future HTTP Request that is being sent to that particular host. use Firefox::Marionette(); use UUID(); my $firefox = Firefox::Marionette->new(); my $uuid = UUID::uuid(); $firefox->add_site_header( 'metacpan.org', 'Track-my-automated-tests' => $uuid ); $firefox->go('https://metacpan.org/'); these headers are added to any existing headers going to the metacpan.org site, but no other site. To clear site headers, see the delete_site_header method addons returns if pre-existing addons (extensions/themes) are allowed to run. This will be true for Firefox versions less than 55, as -safe-mode cannot be automated. alert_text Returns the message shown in a currently displayed modal message box alive This method returns true or false depending on if the Firefox process is still running. application_type returns the application type for the Marionette protocol. Should be 'gecko'. async_script accepts a scalar containing a javascript function that is executed in the browser. This method returns itself to aid in chaining methods. The executing javascript is subject to the script timeout, which, by default is 30 seconds. attribute accepts an element as the first parameter and a scalar attribute name as the second parameter. It returns the initial value of the attribute with the supplied name. This method will return the initial content from the HTML source code, the property method will return the current content. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/'); my $element = $firefox->find_id('metacpan_search-input'); !defined $element->attribute('value') or die "attribute is defined but did not exist in the html source!"; $element->type('Test::More'); !defined $element->attribute('value') or die "attribute has changed but only the property should have changed!"; await accepts a subroutine reference as a parameter and then executes the subroutine. If a not found exception is thrown, this method will sleep for sleep_time_in_ms milliseconds and then execute the subroutine again. When the subroutine executes successfully, it will return what the subroutine returns. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(sleep_time_in_ms => 5)->go('https://metacpan.org/'); $firefox->find_id('metacpan_search-input')->type('Test::More'); $firefox->await(sub { $firefox->find_class('autocomplete-suggestion'); })->click(); back causes the browser to traverse one step backward in the joint history of the current browsing context. The browser will wait for the one step backward to complete or the session's page_load duration to elapse before returning, which, by default is 5 minutes. This method returns itself to aid in chaining methods. debug accept a boolean and return the current value of the debug setting. This allows the dynamic setting of debug. default_binary_name just returns the string 'firefox'. Only of interest when sub-classing. browser_version This method returns the current version of firefox. bye accepts a subroutine reference as a parameter and then executes the subroutine. If the subroutine executes successfully, this method will sleep for sleep_time_in_ms milliseconds and then execute the subroutine again. When a not found exception is thrown, this method will return itself to aid in chaining methods. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/'); $firefox->find_id('metacpan_search-input')->type('Test::More'); $firefox->await(sub { $firefox->find_class('autocomplete-suggestion'); })->click(); $firefox->bye(sub { $firefox->find_name('metacpan_search-input') })->await(sub { $firefox->interactive() && $firefox->find_partial('Download') })->click(); capabilities returns the capabilities of the current firefox binary. You can retrieve timeouts or a proxy with this method. certificate_as_pem accepts a certificate stored in the Firefox database as a parameter and returns a PEM encoded X.509 certificate as a string. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(); # Generating a ca-bundle.crt to STDOUT from the current firefox instance foreach my $certificate (sort { $a->display_name() cmp $b->display_name } $firefox->certificates()) { if ($certificate->is_ca_cert()) { print '# ' . $certificate->display_name() . "\n" . $firefox->certificate_as_pem($certificate) . "\n"; } } The ca-bundle-for-firefox command that is provided as part of this distribution does this. certificates returns a list of all known certificates in the Firefox database. use Firefox::Marionette(); use v5.10; # Sometimes firefox can neglect old certificates. See https://bugzilla.mozilla.org/show_bug.cgi?id=1710716 my $firefox = Firefox::Marionette->new(); foreach my $certificate (grep { $_->is_ca_cert() && $_->not_valid_after() < time } $firefox->certificates()) { say "The " . $certificate->display_name() " . certificate has expired and should be removed"; print 'PEM Encoded Certificate ' . "\n" . $firefox->certificate_as_pem($certificate) . "\n"; } This method returns itself to aid in chaining methods. child_error This method returns the $? (CHILD_ERROR) for the Firefox process, or undefined if the process has not yet exited. chrome changes the scope of subsequent commands to chrome context. This allows things like interacting with firefox menu's and buttons outside of the browser window. use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new()->chrome(); $firefox->script(...); # running script in chrome context $firefox->content(); See the context method for an alternative methods for changing the context. chrome_window_handle returns an server-assigned integer identifiers for the current chrome window that uniquely identifies it within this Marionette instance. This can be used to switch to this window at a later point. This corresponds to a window that may itself contain tabs. This method is replaced by window_handle and appropriate context calls for Firefox 94 and after . chrome_window_handles returns identifiers for each open chrome window for tests interested in managing a set of chrome windows and tabs separately. This method is replaced by window_handles and appropriate context calls for Firefox 94 and after . clear accepts a element as the first parameter and clears any user supplied input clear_pref accepts a preference name and restores it to the original value. See the get_pref and set_pref methods to get a preference value and to set to it to a particular value. This method returns itself to aid in chaining methods. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(); $firefox->clear_pref('browser.search.defaultenginename'); click accepts a element as the first parameter and sends a 'click' to it. The browser will wait for any page load to complete or the session's page_load duration to elapse before returning, which, by default is 5 minutes. The click method is also used to choose an option in a select dropdown. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(visible => 1)->go('https://ebay.com'); my $select = $firefox->find_tag('select'); foreach my $option ($select->find_tag('option')) { if ($option->property('value') == 58058) { # Computers/Tablets & Networking $option->click(); } } close_current_chrome_window_handle closes the current chrome window (that is the entire window, not just the tabs). It returns a list of still available chrome window handles. You will need to switch_to_window to use another window. close_current_window_handle closes the current window/tab. It returns a list of still available window/tab handles. content changes the scope of subsequent commands to browsing context. This is the default for when firefox starts and restricts commands to operating in the browser window only. use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new()->chrome(); $firefox->script(...); # running script in chrome context $firefox->content(); See the context method for an alternative methods for changing the context. context accepts a string as the first parameter, which may be either 'content' or 'chrome'. It returns the context type that is Marionette's current target for browsing context scoped commands. use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new(); if ($firefox->context() eq 'content') { say "I knew that was going to happen"; } my $old_context = $firefox->context('chrome'); $firefox->script(...); # running script in chrome context $firefox->context($old_context); See the content and chrome methods for alternative methods for changing the context. cookies returns the contents of the cookie jar in scalar or list context. use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new()->go('https://github.com'); foreach my $cookie ($firefox->cookies()) { if (defined $cookie->same_site()) { say "Cookie " . $cookie->name() . " has a SameSite of " . $cookie->same_site(); } else { warn "Cookie " . $cookie->name() . " does not have the SameSite attribute defined"; } } css accepts an element as the first parameter and a scalar CSS property name as the second parameter. It returns the value of the computed style for that property. use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/'); say $firefox->find_id('metacpan_search-input')->css('height'); current_chrome_window_handle see chrome_window_handle. delete_certificate accepts a certificate stored in the Firefox database as a parameter and deletes/distrusts the certificate from the Firefox database. use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new(); foreach my $certificate ($firefox->certificates()) { if ($certificate->is_ca_cert()) { $firefox->delete_certificate($certificate); } else { say "This " . $certificate->display_name() " certificate is NOT a certificate authority, therefore it is not being deleted"; } } say "Good luck visiting a HTTPS website!"; This method returns itself to aid in chaining methods. delete_cookie deletes a single cookie by name. Accepts a scalar containing the cookie name as a parameter. This method returns itself to aid in chaining methods. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new()->go('https://github.com'); foreach my $cookie ($firefox->cookies()) { warn "Cookie " . $cookie->name() . " is being deleted"; $firefox->delete_cookie($cookie->name()); } foreach my $cookie ($firefox->cookies()) { die "Should be no cookies here now"; } delete_cookies here be cookie monsters! This method returns itself to aid in chaining methods. delete_header accepts a list of HTTP header names to delete from future HTTP Requests. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(); $firefox->delete_header( 'User-Agent', 'Accept', 'Accept-Encoding' ); will remove the User-Agent , Accept and Accept-Encoding headers from all future requests This method returns itself to aid in chaining methods. delete_login accepts a login as a parameter. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(); foreach my $login ($firefox->logins()) { if ($login->user() eq 'me@example.org') { $firefox->delete_login($login); } } will remove the logins with the username matching 'me@example.org'. This method returns itself to aid in chaining methods. delete_logins This method empties the password database. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(); $firefox->delete_logins(); This method returns itself to aid in chaining methods. delete_session deletes the current WebDriver session. delete_site_header accepts a host name and a list of HTTP headers names to delete from future HTTP Requests. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(); $firefox->delete_header( 'metacpan.org', 'User-Agent', 'Accept', 'Accept-Encoding' ); will remove the User-Agent , Accept and Accept-Encoding headers from all future requests to metacpan.org. This method returns itself to aid in chaining methods. developer returns true if the current version of firefox is a developer edition (does the minor version number end with an 'b\d+'?) version. dismiss_alert dismisses a currently displayed modal message box download accepts a filesystem path and returns a matching filehandle. This is trivial for locally running firefox, but sufficiently complex to justify the method for a remote firefox running over ssh. use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new( host => '10.1.2.3' )->go('https://metacpan.org/'); $firefox->find_class('page-content')->find_id('metacpan_search-input')->type('Test::More'); $firefox->await(sub { $firefox->find_class('autocomplete-suggestion'); })->click(); $firefox->find_partial('Download')->click(); while(!$firefox->downloads()) { sleep 1 } foreach my $path ($firefox->downloads()) { my $handle = $firefox->download($path); # do something with downloaded file handle } downloading returns true if any files in downloads end in .part use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/'); $firefox->find_class('page-content')->find_id('metacpan_search-input')->type('Test::More'); $firefox->await(sub { $firefox->find_class('autocomplete-suggestion'); })->click(); $firefox->find_partial('Download')->click(); while(!$firefox->downloads()) { sleep 1 } while($firefox->downloading()) { sleep 1 } foreach my $path ($firefox->downloads()) { say $path; } downloads returns a list of file paths (including partial downloads) of downloads during this Firefox session. use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/'); $firefox->find_class('page-content')->find_id('metacpan_search-input')->type('Test::More'); $firefox->await(sub { $firefox->find_class('autocomplete-suggestion'); })->click(); $firefox->find_partial('Download')->click(); while(!$firefox->downloads()) { sleep 1 } foreach my $path ($firefox->downloads()) { say $path; } error_message This method returns a human readable error message describing how the Firefox process exited (assuming it started okay). On Win32 platforms this information is restricted to exit code. execute This utility method executes a command with arguments and returns STDOUT as a chomped string. It is a simple method only intended for the Firefox::Marionette::* modules. fill_login This method searches the Password Manager for an appropriate login for any form on the current page. The form must match the host, the action attribute and the user and password field names. use Firefox::Marionette(); use IO::Prompt(); my $firefox = Firefox::Marionette->new(); my $firefox = Firefox::Marionette->new(); my $url = 'https://github.com'; my $user = 'me@example.org'; my $password = IO::Prompt::prompt(-echo => q[*], "Please enter the password for the $user account when logging into $url:"); $firefox->add_login(host => $url, user => $user, password => 'qwerty', user_field => 'login', password_field => 'password'); $firefox->go("$url/login"); $firefox->fill_login(); find accepts an xpath expression as the first parameter and returns the first element that matches this expression.

This directory will be packaged up as an unsigned xpi file. * path to a top level file (such as manifest.json ) in a directory containing firefox extension source code . This directory will be packaged up as an unsigned xpi file. and an optional true/false second parameter to indicate if the xpi file should be a temporary extension (just for the existence of this browser instance). Unsigned xpi files may only be loaded temporarily (except for nightly firefox installations ).

Only of interest when sub-classing. marionette_protocol returns the version for the Marionette protocol. Current most recent version is '3'. maximise maximises the firefox window. This method returns itself to aid in chaining methods. mime_types returns a list of MIME types that will be downloaded by firefox and made available from the downloads method use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new(mime_types => [ 'application/pkcs10' ]) foreach my $mime_type ($firefox->mime_types()) { say $mime_type; } minimise minimises the firefox window. This method returns itself to aid in chaining methods. mouse_down accepts a parameter describing which mouse button the method should apply to (left, middle or right) and returns an action for use in the perform method that corresponding with a mouse button being depressed. mouse_move accepts a element parameter, or a ( x => 0, y => 0 ) type hash manually describing exactly where to move the mouse to and returns an action for use in the perform method that corresponding with such a mouse movement, either to the specified co-ordinates or to the middle of the supplied element parameter. Other parameters that may be passed are listed below; * origin - the origin of the C( 0, y => 0)> co-ordinates. Should be either viewport, pointer or an element. * duration - Number of milliseconds over which to distribute the move. If not defined, the duration defaults to 0. This method returns itself to aid in chaining methods. mouse_up accepts a parameter describing which mouse button the method should apply to (left, middle or right) and returns an action for use in the perform method that corresponding with a mouse button being released. new accepts an optional hash as a parameter. Allowed keys are below; * addons - should any firefox extensions and themes be available in this session. This defaults to "0". * binary - use the specified path to the Firefox binary, rather than the default path. * capabilities - use the supplied capabilities object, for example to set whether the browser should accept insecure certs or whether the browser should use a proxy. * chatty - Firefox is extremely chatty on the network, including checking for the lastest malware/phishing sites, updates to firefox/etc. This option is therefore off ("0") by default, however, it can be switched on ("1") if required. Even with chatty switched off, connections to firefox.settings.services.mozilla.com will still be made . The only way to prevent this seems to be to set firefox.settings.services.mozilla.com to 127.0.0.1 via /etc/hosts . NOTE: that this option only works when profile_name/profile is not specified. * console - show the browser console when the browser is launched. This defaults to "0" (off). * debug - should firefox's debug to be available via STDERR. This defaults to "0". Any ssh connections will also be printed to STDERR. This defaults to "0" (off). This setting may be updated by the debug method. If this option is not a boolean (0|1), the value will be passed to the MOZ_LOG option on the command line of the firefox binary to allow extra levels of debug. * developer - only allow a developer edition to be launched. This defaults to "0" (off). * devtools - begin the session with the devtools window opened in a separate window. * height - set the height of the initial firefox window * har - begin the session with the devtools window opened in a separate window. The HAR Export Trigger addon will be loaded into the new session automatically, which means that -safe-mode will not be activated for this session AND this functionality will only be available for Firefox 61+. * host - use ssh to create and automate firefox on the specified host. See REMOTE AUTOMATION OF FIREFOX VIA SSH. The user will default to the current user name (see the user parameter to change this). Authentication should be via public keys loaded into the local ssh-agent . * implicit - a shortcut to allow directly providing the implicit timeout, instead of needing to use timeouts from the capabilities parameter. Overrides all longer ways. * index - a parameter to allow the user to specify a specific firefox instance to survive and reconnect to. It does not do anything else at the moment. See the survive parameter. * kiosk - start the browser in kiosk mode. * mime_types - any MIME types that Firefox will encounter during this session. MIME types that are not specified will result in a hung browser (the File Download popup will appear). * nightly - only allow a nightly release to be launched. This defaults to "0" (off). * port - if the "host" parameter is also set, use ssh to create and automate firefox via the specified port. See REMOTE AUTOMATION OF FIREFOX VIA SSH. * page_load - a shortcut to allow directly providing the page_load timeout, instead of needing to use timeouts from the capabilities parameter. Overrides all longer ways. * profile - create a new profile based on the supplied profile. NOTE: firefox ignores any changes made to the profile on the disk while it is running, instead, use the set_pref and clear_pref methods to make changes while firefox is running. * profile_name - pick a specific existing profile to automate, rather than creating a new profile. Firefox refuses to allow more than one instance of a profile to run at the same time. Profile names can be obtained by using the Firefox::Marionette::Profile::names() method. NOTE: firefox ignores any changes made to the profile on the disk while it is running, instead, use the set_pref and clear_pref methods to make changes while firefox is running. * reconnect - an experimental parameter to allow a reconnection to firefox that a connection has been discontinued. See the survive parameter. * scp - force the scp protocol when transferring files to remote hosts via ssh. See REMOTE AUTOMATION OF FIREFOX VIA SSH and the --scp-only option in the ssh-auth-cmd-marionette script in this distribution. * script - a shortcut to allow directly providing the script timeout, instead of needing to use timeouts from the capabilities parameter. Overrides all longer ways. * seer - this option is switched off "0" by default. When it is switched on "1", it will activate the various speculative and pre-fetch options for firefox. NOTE: that this option only works when profile_name/profile is not specified. * sleep_time_in_ms - the amount of time (in milliseconds) that this module should sleep when unsuccessfully calling the subroutine provided to the await or bye methods. This defaults to "1" millisecond. * survive - if this is set to a true value, firefox will not automatically exit when the object goes out of scope. See the reconnect parameter for an experimental technique for reconnecting. * trust - give a path to a root certificate encoded as a PEM encoded X.509 certificate that will be trusted for this session. * timeouts - a shortcut to allow directly providing a timeout object, instead of needing to use timeouts from the capabilities parameter. Overrides the timeouts provided (if any) in the capabilities parameter. * user - if the "host" parameter is also set, use ssh to create and automate firefox with the specified user. See REMOTE AUTOMATION OF FIREFOX VIA SSH. The user will default to the current user name. Authentication should be via public keys loaded into the local ssh-agent . * via - specifies a proxy jump box to be used to connect to a remote host. See the host parameter. * visible - should firefox be visible on the desktop. This defaults to "0". When moving from a X11 platform to another X11 platform, you can set visible to 'local' to enable X11 forwarding . See X11 FORWARDING WITH FIREFOX. * waterfox - only allow a binary that looks like a waterfox version to be launched. * width - set the width of the initial firefox window This method returns a new Firefox::Marionette object, connected to an instance of firefox . In a non MacOS/Win32/Cygwin environment, if necessary (no DISPLAY variable can be found and the visible parameter to the new method has been set to true) and possible (Xvfb can be executed successfully), this method will also automatically start an Xvfb instance. use Firefox::Marionette(); my $remote_darwin_firefox = Firefox::Marionette->new( debug => 'timestamp,nsHttp:1', host => '10.1.2.3', trust => '/path/to/root_ca.pem', binary => '/Applications/Firefox.app/Contents/MacOS/firefox' ); # start a temporary profile for a remote firefox and load a new CA into the temp profile ... foreach my $profile_name (Firefox::Marionette::Profile->names()) { my $firefox_with_existing_profile = Firefox::Marionette->new( profile_name => $profile_name, visible => 1 ); ... } new_window accepts an optional hash as the parameter. Allowed keys are below; * focus - a boolean field representing if the new window be opened in the foreground (focused) or background (not focused). Defaults to false. * private - a boolean field representing if the new window should be a private window. Defaults to false. * type - the type of the new window. Can be one of 'tab' or 'window'. Defaults to 'tab'. Returns the window handle for the new window. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(); my $window_handle = $firefox->new_window(type => 'tab'); $firefox->switch_to_window($window_handle); new_session creates a new WebDriver session. It is expected that the caller performs the necessary checks on the requested capabilities to be WebDriver conforming. The WebDriver service offered by Marionette does not match or negotiate capabilities beyond type and bounds checks. nightly returns true if the current version of firefox is a nightly release (does the minor version number end with an 'a1'?) paper_sizes returns a list of all the recognised names for paper sizes, such as A4 or LEGAL. pause accepts a parameter in milliseconds and returns a corresponding action for the perform method that will cause a pause in the chain of actions given to the perform method. pdf accepts a optional hash as the first parameter with the following allowed keys; * landscape - Paper orientation. Boolean value. Defaults to false * margin - A hash describing the margins. The hash may have the following optional keys, 'top', 'left', 'right' and 'bottom'.

Both keys are in cm and default to US letter size. See the 'size' key. * page_ranges - A list of the pages to print. Available for Firefox 96 and after. * print_background - Print background graphics. Boolean value. Defaults to false. * raw - rather than a file handle containing the PDF, the binary PDF will be returned. * scale - Scale of the webpage rendering. Defaults to 1. * size - The desired size (width and height) of the pdf, specified by name. See the page key for an alternative and the paper_sizes method for a list of accepted page size names. * shrink_to_fit - Whether or not to override page size as defined by CSS. Boolean value. Defaults to true. returns a File::Temp object containing a PDF encoded version of the current page for printing. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/'); my $handle = $firefox->pdf(); foreach my $paper_size ($firefox->paper_sizes()) { $handle = $firefox->pdf(size => $paper_size, landscape => 1, margin => { top => 0.5, left => 1.5 }); ... print $firefox->pdf(page => { width => 21, height => 27 }, raw => 1); ... } perform accepts a list of actions (see mouse_up, mouse_down, mouse_move, pause, key_down and key_up) and performs these actions in sequence. This allows fine control over interactions, including sending right clicks to the browser and sending Control, Alt and other special keys. The release method will complete outstanding actions (such as mouse_up or key_up actions). use Firefox::Marionette(); use Firefox::Marionette::Keys qw(:all); use Firefox::Marionette::Buttons qw(:all); my $firefox = Firefox::Marionette->new(); $firefox->chrome()->perform( $firefox->key_down(CONTROL()), $firefox->key_down('l'), $firefox->key_up('l'), $firefox->key_up(CONTROL()) )->content(); $firefox->go('https://metacpan.org'); my $help_button = $firefox->find_class('btn search-btn help-btn'); $firefox->perform( $firefox->mouse_move($help_button), $firefox->mouse_down(RIGHT_BUTTON()), $firefox->pause(4), $firefox->mouse_up(RIGHT_BUTTON()), ); See the release method for an alternative for manually specifying all the mouse_up and key_up methods profile_directory returns the profile directory used by the current instance of firefox. This is mainly intended for debugging firefox. Firefox is not designed to cope with these files being altered while firefox is running. property accepts an element as the first parameter and a scalar attribute name as the second parameter. It returns the current value of the property with the supplied name. This method will return the current content, the attribute method will return the initial content from the HTML source code. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/'); my $element = $firefox->find_id('metacpan_search-input'); $element->property('value') eq '' or die "Initial property should be the empty string"; $element->type('Test::More'); $element->property('value') eq 'Test::More' or die "This property should have changed!"; # OR getting the innerHTML property my $title = $firefox->find_tag('title')->property('innerHTML'); # same as $firefox->title(); pwd_mgr_lock Accepts a new primary password and locks the Password Manager with it. use Firefox::Marionette(); use IO::Prompt(); my $firefox = Firefox::Marionette->new(); my $password = IO::Prompt::prompt(-echo => q[*], "Please enter the password for the Firefox Password Manager:"); $firefox->pwd_mgr_lock($password); $firefox->pwd_mgr_logout(); # now no-one can access the Password Manager Database without the value in $password This method returns itself to aid in chaining methods. pwd_mgr_login Accepts the primary password and allows the user to access the Password Manager . use Firefox::Marionette(); use IO::Prompt(); my $firefox = Firefox::Marionette->new( profile_name => 'default' ); my $password = IO::Prompt::prompt(-echo => q[*], "Please enter the password for the Firefox Password Manager:"); $firefox->pwd_mgr_login($password); ... # access the Password Database. ... $firefox->pwd_mgr_logout(); ... # no longer able to access the Password Database. This method returns itself to aid in chaining methods. pwd_mgr_logout Logs the user out of being able to access the Password Manager . use Firefox::Marionette(); use IO::Prompt(); my $firefox = Firefox::Marionette->new( profile_name => 'default' ); my $password = IO::Prompt::prompt(-echo => q[*], "Please enter the password for the Firefox Password Manager:"); $firefox->pwd_mgr_login($password); ... # access the Password Database. ... $firefox->pwd_mgr_logout(); ... # no longer able to access the Password Database. This method returns itself to aid in chaining methods. pwd_mgr_needs_login returns true or false if the Password Manager has been locked and needs a primary password to access it. use Firefox::Marionette(); use IO::Prompt(); my $firefox = Firefox::Marionette->new( profile_name => 'default' ); if ($firefox->pwd_mgr_needs_login()) { my $password = IO::Prompt::prompt(-echo => q[*], "Please enter the password for the Firefox Password Manager:"); $firefox->pwd_mgr_login($password); } quit Marionette will stop accepting new connections before ending the current session, and finally attempting to quit the application. This method returns the $? (CHILD_ERROR) value for the Firefox process rect accepts a element as the first parameter and returns the current position and size of the element refresh refreshes the current page. The browser will wait for the page to completely refresh or the session's page_load duration to elapse before returning, which, by default is 5 minutes. This method returns itself to aid in chaining methods. release completes any outstanding actions issued by the perform method. use Firefox::Marionette(); use Firefox::Marionette::Keys qw(:all); use Firefox::Marionette::Buttons qw(:all); my $firefox = Firefox::Marionette->new(); $firefox->chrome()->perform( $firefox->key_down(CONTROL()), $firefox->key_down('l'), )->release()->content(); $firefox->go('https://metacpan.org'); my $help_button = $firefox->find_class('btn search-btn help-btn'); $firefox->perform( $firefox->mouse_move($help_button), $firefox->mouse_down(RIGHT_BUTTON()), $firefox->pause(4), )->release(); restart restarts the browser. After the restart, capabilities should be restored. The same profile settings should be applied, but the current state of the browser (such as the uri will be reset (like after a normal browser restart). This method is primarily intended for use by the update method. Not sure if this is useful by itself. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(); $firefox->restart(); # but why? This method returns itself to aid in chaining methods. root_directory this is the root directory for the current instance of firefox. The directory may exist on a remote server. For debugging purposes only. screen_orientation returns the current browser orientation. This will be one of the valid primary orientation values 'portrait-primary', 'landscape-primary', 'portrait-secondary', or 'landscape-secondary'. This method is only currently available on Android (Fennec). script accepts a scalar containing a javascript function body that is executed in the browser, and an optional hash as a second parameter. Allowed keys are below; * args - The reference to a list is the arguments passed to the function body. * filename - Filename of the client's program where this script is evaluated. * line - Line in the client's program where this script is evaluated. * new - Forces the script to be evaluated in a fresh sandbox. Note that if it is undefined, the script will normally be evaluated in a fresh sandbox. * sandbox - Name of the sandbox to evaluate the script in. The sandbox is cached for later re-use on the same window object if new is false. If he parameter is undefined, the script is evaluated in a mutable sandbox. If the parameter is "system", it will be evaluated in a sandbox with elevated system privileges, equivalent to chrome space. * timeout - A timeout to override the default script timeout, which, by default is 30 seconds. Returns the result of the javascript function. When a parameter is an element (such as being returned from a find type operation), the script method will automatically translate that into a javascript object. Likewise, when the result being returned in a script method is an element it will be automatically translated into a perl object. use Firefox::Marionette(); use v5.10; my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/'); if (my $element = $firefox->script('return document.getElementsByName("metacpan_search-input")[0];')) { say "Lucky find is a " . $element->tag_name() .

If an element is passed as a parameter, the screenshot will be restricted to the element. If an element is not passed as a parameter and the current context is 'chrome', a screenshot of the current viewport will be returned. If an element is not passed as a parameter and the current context is 'content', a screenshot of the current frame will be returned. The parameters after the element parameter are taken to be a optional hash with the following allowed keys; * hash - return a SHA256 hex encoded digest of the PNG image rather than the image itself * full - take a screenshot of the whole document unless the first element parameter has been supplied. * raw - rather than a file handle containing the screenshot, the binary PNG image will be returned. * scroll - scroll to the element supplied * highlights - a reference to a list containing elements to draw a highlight around. Not available in Firefox 70 onwards. scroll accepts a element as the first parameter and scrolls to it. The optional second parameter is the same as for the scrollInfoView method. use Firefox::Marionette(); my $firefox = Firefox::Marionette->new(visible => 1)->go('https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView'); my $link = $firefox->find_id('content')->find_link('Examples'); $firefox->scroll($link); $firefox->scroll($link, 1); $firefox->scroll($link, { behavior => 'smooth', block => 'center' }); $firefox->scroll($link, { block => 'end', inline => 'nearest' }); send_alert_text sends keys to the input field of a currently displayed modal message box set_pref accepts a preference name and the new value to set it to. See the get_pref and clear_pref methods to get a preference value and to restore it to it's original value.

If not defined, deltaY defaults to 0. win32_organisation accepts a parameter of a Win32 product name and returns the matching organisation. Only of interest when sub-classing. win32_product_names returns a hash of known Windows product names (such as 'Mozilla Firefox') with priority orders. The lower the priority will determine the order that this module will check for the existence of this product. Only of interest when sub-classing. window_handle returns the current window's handle. On desktop this typically corresponds to the currently selected tab. returns an opaque server-assigned identifier to this window that uniquely identifies it within this Marionette instance. This can be used to switch to this window at a later point. use Firefox::Marionette(); use 5.010; my $firefox = Firefox::Marionette->new(); my $original_window_uuid = $firefox->window_handle(); window_handles returns a list of top-level browsing contexts. On desktop this typically corresponds to the set of open tabs for browser windows, or the window itself for non-browser chrome windows. Each window handle is assigned by the server and is guaranteed unique, however the return array does not have a specified ordering. use Firefox::Marionette(); use 5.010; my $firefox = Firefox::Marionette->new(); my $original_window_uuid = $firefox->window_handle(); $firefox->new_window( type => 'tab' ); $firefox->new_window( type => 'window' ); say "There are " . $firefox->window_handles() . " tabs open in total"; say "Across " . $firefox->chrome()->window_handles()->content() . " chrome windows"; window_rect accepts an optional position and size as a parameter, sets the current browser window to that position and size and returns the previous position, size and state of the browser window. If no parameter is supplied, it returns the current position, size and state of the browser window. window_type returns the current window's type. This should be 'navigator:browser'. xvfb_pid returns the pid of the xvfb process if it exists. xvfb_display returns the value for the DISPLAY environment variable if one has been generated for the xvfb environment. xvfb_xauthority returns the value for the XAUTHORITY environment variable if one has been generated for the xvfb environment AUTOMATING THE FIREFOX PASSWORD MANAGER This module allows you to login to a website without ever directly handling usernames and password details. The Password Manager may be preloaded with appropriate passwords and locked, like so; use Firefox::Marionette(); my $firefox = Firefox::Marionette->new( profile_name => 'locked' ); # using a pre-built profile called 'locked' if ($firefox->pwd_mgr_needs_login()) { my $new_password = IO::Prompt::prompt(-echo => q[*], 'Enter the password for the locked profile:'); $firefox->pwd_mgr_login($password); } else { my $new_password = IO::Prompt::prompt(-echo => q[*], 'Enter the new password for the locked profile:'); $firefox->pwd_mgr_lock($password); } ... $firefox->pwd_mgr_logout(); Usernames and passwords (for both HTTP Authentication popups and HTML Form based logins) may be added, viewed and deleted. use WebService::HIBP(); my $hibp = WebService::HIBP->new(); $firefox->add_login(host => 'https://github.com', user => 'me@example.org', password => 'qwerty', user_field => 'login', password_field => 'password'); $firefox->add_login(host => 'https://pause.perl.org', user => 'AUSER', password => 'qwerty', realm => 'PAUSE'); ... foreach my $login ($firefox->logins()) { if ($hibp->password($login->password())) { # does NOT send the password to the HIBP webservice warn "HIBP reports that your password for the " . $login->user() " account at " . $login->host() . " has been found in a data breach"; $firefox->delete_login($login); # how could this possibly help? } } And used to fill in login prompts without explicitly knowing the account details. $firefox->go('https://pause.perl.org/pause/authenquery')->accept_alert(); # this goes to the page and submits the http auth popup $firefox->go('https://github.com/login')->fill_login(); # fill the login and password fields without needing to see them REMOTE AUTOMATION OF FIREFOX VIA SSH use Firefox::Marionette(); my $firefox = Firefox::Marionette->new( host => 'remote.example.org', debug => 1 ); $firefox->go('https://metacpan.org/'); # OR specify a different user to login as ... my $firefox = Firefox::Marionette->new( host => 'remote.example.org', user => 'R2D2', debug => 1 ); $firefox->go('https://metacpan.org/'); # OR specify a different port to connect to my $firefox = Firefox::Marionette->new( host => 'remote.example.org', port => 2222, debug => 1 ); $firefox->go('https://metacpan.org/'); # OR use a proxy host to jump via to the final host my $firefox = Firefox::Marionette->new( host => 'remote.example.org', port => 2222, via => 'user@secure-jump-box.example.org:42222', debug => 1, ); $firefox->go('https://metacpan.org/'); This module has support for creating and automating an instance of Firefox on a remote node. It has been tested against a number of operating systems, including recent version of Windows 10 or Windows Server 2019 , OS X, and Linux and BSD distributions. It expects to be able to login to the remote node via public key authentication. It can be further secured via the command option in the OpenSSH authorized_keys file such as; no-agent-forwarding,no-pty,no-X11-forwarding,permitopen="127.0.0.1:*",command="/usr/local/bin/ssh-auth-cmd-marionette" ssh-rsa AAAA ... == user@server As an example, the ssh-auth-cmd-marionette command is provided as part of this distribution. The module will expect to access private keys via the local ssh-agent when authenticating. When using ssh, Firefox::Marionette will attempt to pass the TMPDIR environment variable across the ssh connection to make cleanups easier. In order to allow this, the AcceptEnv setting in the remote sshd configuration should be set to allow TMPDIR, which will look like; AcceptEnv TMPDIR This module uses ControlMaster functionality when using ssh, for a useful speedup of executing remote commands. Unfortunately, when using ssh to move from a cygwin , Windows 10 or Windows Server 2019 node to a remote environment, we cannot use ControlMaster, because at this time, Windows does not support ControlMaster and therefore this type of automation is still possible, but slower than other client platforms. WEBGL There are a number of steps to getting WebGL to work correctly; 1. The addons parameter to the new method must be set. This will disable -safe-mode 2. The visible parameter to the new method must be set. This is due to an existing bug in Firefox . 3. It can be tricky getting WebGL to work with a Xvfb instance. glxinfo can be useful to help debug issues in this case. The mesa-dri-drivers rpm is also required for Redhat systems. With all those conditions being met, WebGL can be enabled like so; use Firefox::Marionette(); my $firefox = Firefox::Marionette->new( addons => 1, visible => 1 ); if ($firefox->script(q[let c = document.createElement('canvas'); return c.getContext('webgl2') ? true : c.getContext('experimental-webgl') ? true : false;])) { $firefox->go("https://get.webgl.org/"); } else { die "WebGL is not supported"; } X11 FORWARDING WITH FIREFOX This is an experimental addition to this module. X11 Forwarding allows you to launch a remote firefox via ssh and have it visually appear in your local X11 desktop. This can be accomplished with the following code; use Firefox::Marionette(); my $firefox = Firefox::Marionette->new( host => 'remote-x11.example.org', visible => 'local', debug => 1, ); $firefox->go('https://metacpan.org'); Feedback is welcome on any odd X11 workarounds that might be required for different platforms. UBUNTU AND FIREFOX DELIVERED VIA SNAP Ubuntu 22.04 LTS is packaging firefox as a snap . This breaks the way that this module expects to be able to run, specifically, being able to setup a firefox profile in a systems temporary directory (/tmp or $TMPDIR in most Unix based systems) and allow the operating system to cleanup old directories caused by exceptions / network failures / etc. Because of this design decision, attempting to run a snap version of firefox will simply result in firefox hanging, unable to read it's custom profile directory and hence unable to read the marionette port configuration entry. Which would be workable except that; there does not appear to be _any_ way to detect that a snap firefox will run (/usr/bin/firefox is a bash shell which eventually runs the snap firefox), so there is no way to know (heuristics aside) if a normal firefox or a snap firefox will be launched by execing 'firefox'. It seems the only way to fix this issue (as documented in more than a few websites) is; 1. sudo snap remove firefox 2. sudo add-apt-repository -y ppa:mozillateam/ppa 3. sudo apt update 4. sudo apt install -t 'o=LP-PPA-mozillateam' firefox 5. echo -e "Package: firefox*\nPin: release o=LP-PPA-mozillateam\nPin-Priority: 501" >/tmp/mozillateamppa 6. sudo mv /tmp/mozillateamppa /etc/apt/preferences.d/mozillateamppa If anyone is aware of a reliable method to detect if a snap firefox is going to launch vs a normal firefox, I would love to know about it. This technique is used in the setup-for-firefox-marionette-build.sh script in this distribution. DIAGNOSTICS Failed to correctly setup the Firefox process The module was unable to retrieve a session id and capabilities from Firefox when it requests a new_session as part of the initial setup of the connection to Firefox.

CONFIGURATION AND ENVIRONMENT Firefox::Marionette requires no configuration files or environment variables. It will however use the DISPLAY and XAUTHORITY environment variables to try to connect to an X Server. It will also use the HTTP_PROXY, HTTPS_PROXY, FTP_PROXY and ALL_PROXY environment variables as defaults if the session capabilities do not specify proxy information. DEPENDENCIES Firefox::Marionette requires the following non-core Perl modules * JSON * URI * XML::Parser * Time::Local INCOMPATIBILITIES None reported. Always interested in any products with marionette support that this module could be patched to work with. BUGS AND LIMITATIONS DOWNLOADING USING GO METHOD When using the go method to go directly to a URL containing a downloadable file, Firefox can hang. You can work around this by setting the page_load_strategy to none like below; #! /usr/bin/perl use strict; use warnings; use Firefox::Marionette(); my $firefox = Firefox::Marionette->new( capabilities => Firefox::Marionette::Capabilities->new( page_load_strategy => 'none' ) ); $firefox->go("https://github.com/david-dick/firefox-marionette/archive/refs/heads/master.zip"); while(!$firefox->downloads()) { sleep 1 } while($firefox->downloading()) { sleep 1 } foreach my $path ($firefox->downloads()) { warn "$path has been downloaded"; } $firefox->quit(); MISSING METHODS Currently the following Marionette methods have not been implemented; * WebDriver:SetScreenOrientation To report a bug, or view the current list of bugs, please visit https://github.com/david-dick/firefox-marionette/issues SEE ALSO * MozRepl * Selenium::Firefox * Firefox::Application * Mozilla::Mechanize * Gtk2::MozEmbed AUTHOR David Dick ACKNOWLEDGEMENTS Thanks to the entire Mozilla organisation for a great browser and to the team behind Marionette for providing an interface for automation.
