All notable changes to this program is documented in this file.
0.27.0 (2020-07-27)
### Known problems
- _macOS 10.15 (Catalina):_
Due to the requirement from Apple that all programs must be
notarized, geckodriver will not work on Catalina if you manually
download it through another notarized program, such as Firefox.
Whilst we are working on a repackaging fix for this problem, you
can find more details on how to work around this issue in the
[macOS notarization] section of the documentation.
### Added
- To set environment variables for the launched Firefox for Android,
it is now possible to add an `env` object on `moz:firefoxOptions`
(note: this is not supported for Firefox Desktop)
- Support for print-to-PDF
The newly standardised WebDriver [Print] endpoint provides a way to
render pages to a paginated PDF representation. This endpoint is
supported by geckodriver when using Firefox version ≥78.
- Support for same-site cookies
Cookies can now be set with a `same-site` parameter, and the value
of that parameter will be returned when cookies are
retrieved. Requires Firefox version ≥79. Thanks to [Peter Major] for
the patch.
### Fixed
- _Android:_
* Firefox running on Android devices can now be controlled from a
Windows host.
* Setups with multiple connected Android devices are now supported.
* Improved cleanup of configuration files. This prevents crashes if
the application is started manually after launching it through
- Windows and Linux binaries are again statically linked.
0.26.0 (2019-10-12, `e9783a644016'`)
Note that with this release the minimum recommended Firefox version
has changed to Firefox ≥60.
### Known problems
- _macOS 10.15 (Catalina):_
Due to the recent requirement from Apple that all programs must
be notarized, geckodriver will not work on Catalina if you manually
download it through another notarized program, such as Firefox.
Whilst we are working on a repackaging fix for this problem, you
can find more details on how to work around this issue in the
[macOS notarization] section of the documentation.
- _Windows:_
You must still have the [Microsoft Visual Studio redistributable
runtime] installed on your system for the binary to run. This
is a known bug which we weren't able fix for this release.
### Added
- Support for Firefox on Android
Starting with this release geckodriver is able to connect to
Firefox on Android systems, and to control packages based on
Support for Android works by the geckodriver process running on
a host system and Firefox running within either an emulator or
on a physical device connected to the host system. This requires
you to first [enable remote debugging on the Android device].
The WebDriver client must set the [`platformName` capability] to
"`android`" and the `androidPackage` capability within
[`moz:firefoxOptions`] to the Android package name of the Firefox
The full list of new capabilities specific to Android, instructions
how to use them, and examples can be found in the [`moz:firefoxOptions`]
documentation on MDN.
When the session is created, the `platformName` capability will
return "`android`" instead of reporting the platform of the host
### Changed
- Continued Marionette refactoring changes
0.25.0 came with a series of internal changes for how geckodriver
communicates with Firefox over the Marionette protocol. This
release contains the second half of the refactoring work.
### Fixed
- Connection attempts to Firefox made more reliable
geckodriver now waits for the Marionette handshake before assuming
the session has been established. This should improve reliability
in creating new WebDriver sessions.
- Corrected error codes used during session creation
When a new session was being configured with invalid input data,
the error codes returned was not always consistent. Attempting
to start a session with a malformed capabilities configuration
will now return the [`invalid argument`] error consistently.
0.25.0 (2019-09-09, `bdb64cf16b68`)
__Note to Windows users!__
With this release you must have the [Microsoft Visual Studio redistributable runtime]
installed on your system for the binary to run.
with this particular release that we intend to release a fix for soon.
### Added
- Added support for HTTP `HEAD` requests to the HTTPD
geckodriver now responds correctly to HTTP `HEAD` requests,
which can be used for probing whether it supports a particular API.
Thanks to [Bastien Orivel] for this patch.
- Added support for searching for Nightly’s default path on macOS
If the location of the Firefox binary is not given, geckodriver
will from now also look for the location of Firefox Nightly in
the default locations. The ordered list of search paths on macOS
is as follows:
1. `/Applications/`
2. `$HOME/Applications/`
3. `/Applications/Firefox`
4. `$HOME/Applications/Firefox`
Thanks to [Kriti Singh] for this patch.
- Support for application bundle paths on macOS
It is now possible to pass an application bundle path, such as
`/Applications/` as argument to the `binary` field in
[`moz:firefoxOptions`]. This will be automatically resolved to
the absolute path of the binary when Firefox is started.
Thanks to [Nupur Baghel] for this patch.
- macOS and Windows builds are signed
With this release of geckodriver, executables for macOS and Windows
are signed using the same certificate key as Firefox. This should
help in cases where geckodriver previously got misidentified as
a virus by antivirus software.
### Removed
- Dropped support for legacy Selenium web element references
The legacy way of serialising web elements, using `{"ELEMENT": <UUID>}`,
has been removed in this release. This may break older Selenium
clients and clients which are otherwise not compatible with the
WebDriver standard.
Thanks to [Shivam Singhal] for this patch.
- Removed `--webdriver-port` command-line option
`--webdriver-port <PORT>` was an undocumented alias for `--port`,
initially used for backwards compatibility with clients
prior to Selenium 3.0.0.
### Changed
- Refactored Marionette serialisation
Much of geckodriver’s internal plumbing for serialising WebDriver
requests to Marionette messages has been refactored to decrease
the amount of manual lifting.
This work should have no visible side-effects for users.
Thanks to [Nupur Baghel] for working on this throughout her
Outreachy internship at Mozilla.
- Improved error messages for incorrect command-line usage
### Fixed
- Errors related to incorrect command-line usage no longer hidden
By mistake, earlier versions of geckodriver failed to print incorrect
flag use. With this release problems are again written to stderr.
- Search system path for Firefox binary on BSDs
geckodriver would previously only search the system path for the
`firefox` binary on Linux. Now it supports different BSD flavours
as well.
0.24.0 (2019-01-28, `917474f3473e`)
### Added
- Introduces `strictFileInteractability` capability
The new capability indicates if strict interactability checks
should be applied to `<input type=file>` elements. As strict
interactability checks are off by default, there is a change
in behaviour when using [Element Send Keys] with hidden file
upload controls.
- Added new endpoint `GET /session/{session id}/moz/screenshot/full`
for taking full document screenshots, thanks to Greg Fraley.
- Added new `--marionette-host <hostname>` flag for binding to a
particular interface/IP layer on the system.
- Added new endpoint `POST /session/{session_id}/window/new`
for the [New Window] command to create a new top-level browsing
context, which can be either a window or a tab. The first version
of Firefox supporting this command is Firefox 66.0.
- When using the preference `devtools.console.stdout.content` set to
`true` logging of console API calls like `info()`, `warn()`, and
`error()` can be routed to stdout.
- geckodriver now sets the `app.update.disabledForTesting` preference
to prevent Firefox >= 65 from automatically updating whilst under
### Removed
- ARMv7 HF builds have been discontinued
back in September 2018 that we would stop building for ARM,
but builds can be self-serviced by building from source.
To cross-compile from another host system, you can use this command:
% cargo build --target armv7-unknown-linux-gnueabihf
### Changed
- Allow file uploads to hidden `<input type=file>` elements
Through a series of changes to the WebDriver specification,
geckodriver is now aligned with chromedriver’s behaviour that
allows interaction with hidden `<input type=file>` elements.
This allows WebDriver to be used with various popular web
frameworks that—through indirection—hides the file upload control
and invokes it through other means.
- Allow use of an indefinite script timeout for the [Set Timeouts]
command, thanks to reimu.
### Fixed
- Corrected `Content-Type` of response header to `utf-8` to fix
an HTTP/1.1 compatibility bug.
- Relaxed the deserialization of timeouts parameters to allow unknown
fields for the [Set Timeouts] command.
- Fixed a regression in the [Take Element Screenshot] to not screenshot
the viewport, but the requested element.
0.23.0 (2018-10-03)
This release contains a number of fixes for regressions introduced
in 0.22.0, where we shipped a significant refactoring to the way
geckodriver internally dealt with JSON serialisation.
### Removed
- The POST `/session/{session id}/element/{element id}/tap` endpoint
was removed, thanks to Kerem Kat.
### Changed
- [webdriver crate] upgraded to 0.38.0.
### Fixed
- `desiredCapabilities` and `requiredCapabilities` are again
recognised on session creation
A regression in 0.22.0 caused geckodriver to recognise `desired`
and `required` instead of the correct `desiredCapabilities`
and `requiredCapabilities`. This will have caused significant
problems for users who relied on this legacy Selenium-style
session creation pattern.
Do however note that support for Selenium-styled new session
requests is temporary and that this will be removed sometime
before the 1.0 release.
- `duration` field made optional on pause actions
A regression in 0.22.0 caused the pause action primitive to
require a `duration` field. This has now been fixed so that
pauses in action chains can be achieved with the default duration.
- Log level formatted to expected Marionette input
A regression in 0.22.0 caused the log level to be improperly
formatted when using Firefox pre-releases. This is now fixed so
that the requested log level is correctly interpreted by Marionette.
- `temporary` field on addon installation made optional
A regression in 0.22.0 caused the `temporary` field for POST
`/session/{session id}/moz/addon/install` to be mandatory. This has
now been fixed so that an addon is installed permanently by default.
- SHA1s in version information uses limited number of characters
The SHA1 used in `--version` when building geckodriver from a
git repository is now limited to 12 characters, as it is when
building from an hg checkout. This ensures reproducible builds.
0.22.0 (2018-09-15)
This release marks an important milestone on the path towards
a stable release of geckodriver. Large portions of geckodriver
and the [webdriver] library it is based on has been refactored to
accommodate using [serde] for JSON serialization.
We have also made great strides to improving [WebDriver conformance],
to the extent that geckodriver is now _almost_ entirely conforming
to the standard.
### Added
- Support for WebDriver web element-, web frame-, and web window
identifiers from Firefox.
- Added support for the non-configurable `setWindowRect` capability
from WebDriver.
This capability informs whether the attached browser supports
manipulating the window dimensions and position.
- A new extension capability `moz:geckodriverVersion` is returned
upon session creation.
### Changed
- All JSON serialization and deserialisation has moved from
rustc_serialize to [serde].
- The HTTP status codes used for [script timeout] and [timeout]
errors has changed from Request Timeout (408) to Internal Server
Error (500) in order to not break HTTP/1.1 `Keep-Alive` support,
as HTTP clients interpret the old status code to mean they should
duplicate the request.
- The HTTP/1.1 `Keep-Alive` timeout for persistent connections has
been increased to 90 seconds.
- An [invalid session ID] error is now returned when there is no
active session.
- An [invalid argument] error is now returned when [Add Cookie]
is given invalid parameters.
- The handshake when geckodriver connects to Marionette has been
hardened by killing the Firefox process if it fails.
- The handshake read timeout has been reduced to 10 seconds instead
of waiting forever.
- The HTTP server geckodriver uses, [hyper], has been upgraded to
version 0.12, thanks to [Bastien Orivel].
- geckodriver version number is no longer logged on startup, as
the log level is not configured until a session is created.
The version number is available through `--version`, and now
also through a new `moz:geckodriverVersion` field in the matched
- [webdriver crate] upgraded to 0.37.0.
### Fixed
- Parsing [timeout object] values has been made WebDriver conforming,
by allowing floats as input.
- Implicit downloads of OpenH264 and Widevine plugins has been disabled.
- The commit hash and date displayed when invoking `--version`
is now well-formatted when built from an hg repository, thanks to
[Jeremy Lempereur].
- Many documentation improvements, now published on
0.21.0 (2018-06-15)
Note that with this release of geckodriver the minimum recommended
Firefox and Selenium versions have changed:
- Firefox 57 (and greater)
- Selenium 3.11 (and greater)
### Added
- Support for the chrome element identifier from Firefox.
- The `unhandledPromptBehavior` capability now accepts `accept and
notify`, `dismiss and notify`, and `ignore` options.
Note that the unhandled prompt handler is not fully supported in
Firefox at the time of writing.
### Changed
- Firefox will now be started with the `-foreground` and `-no-remote`
flags if they have not already been specified by the user in
`-foreground` will ensure the application window gets focus when
Firefox is started, and `-no-remote` will prevent remote commands
to this instance of Firefox and also ensure we always start a new
- WebDriver commands that do not have a return value now correctly
return `{value: null}` instead of an empty dictionary.
- The HTTP server now accepts `Keep-Alive` connections.
- Firefox remote protocol command mappings updated.
All Marionette commands changed to make use of the `WebDriver:`
prefixes introduced with Firefox 56.
- Overhaul of Firefox preferences.
Already deprecated preferences in Firefox versions earlier than
57 got removed.
- [webdriver crate] upgraded to 0.36.0.
### Fixed
- Force use of IPv4 network stack.
On certain system configurations, where `localhost` resolves to
an IPv6 address, geckodriver would attempt to connect to Firefox
on the wrong IP stack, causing the connection attempt to time out
after 60 seconds. We now ensure that geckodriver uses IPv4
consistently to both connect to Firefox and for allocating a free
- geckodriver failed to locate the correct Firefox binary if it was
found under a _firefox_ or _firefox-bin_ directory, depending on
the system, because it thought the parent directory was the
- On Unix systems (macOS, Linux), geckodriver falsely reported
non-executable files as valid binaries.
- When stdout and stderr is redirected by geckodriver, a bug prevented
the redirections from taking effect.
0.20.1 (2018-04-06)
### Fixed
- Avoid attempting to kill Firefox process that has stopped.
With the change to allow Firefox enough time to shut down in
0.20.0, geckodriver started unconditionally killing the process
to reap its exit status. This caused geckodriver to inaccurately
report a successful Firefox shutdown as a failure.
The regression should not have caused any functional problems, but
the termination cause and the exit status are now reported correctly.
0.20.0 (2018-03-08)
### Added
- New `--jsdebugger` flag to open the [Browser Toolbox] when Firefox
launches. This is useful for debugging Marionette internals.
- Introduced the temporary, boolean capability
`moz:useNonSpecCompliantPointerOrigin` to disable the WebDriver
conforming behavior of calculating the Pointer Origin.
### Changed
- HTTP status code for the [`StaleElementReference`] error changed
from 400 (Bad Request) to 404 (Not Found).
- Backtraces from geckodriver no longer substitute for missing
Marionette stacktraces.
- [webdriver crate] upgraded to 0.35.0.
### Fixed
- The Firefox process is now given ample time to shut down, allowing
enough time for the Firefox shutdown hang monitor to kick in.
Firefox has an integrated background monitor that observes
long-running threads during shutdown. These threads will be
killed after 63 seconds in the event of a hang. To allow Firefox
to shut down these threads on its own, geckodriver has to wait
that time and some additional seconds.
- Grapheme clusters are now accepted as input for keyboard input
to actions.
Input to the `value` field of the `keyDown` and `keyUp` action
primitives used to only accept single characters, which means
geckodriver would error when a valid grapheme cluster was sent in,
for example with the tamil nadu character U+0BA8 U+0BBF.
Thanks to Greg Fraley for fixing this bug.
- Improved error messages for malformed capability values.
0.19.1 (2017-10-30)

trigger network connections
- Block addons incompatible with E10s
### Fixed
- Marionette stacktraces are now correctly propagated
- Some error messages have been clarified
### Removed
- Removed obsolete `socksUsername` and `socksPassword` proxy
configuration keys because neither were picked up or recognised

Note that with geckodriver 0.19.0 the following versions are recommended:
- Firefox 55.0 (and greater)
- Selenium 3.5 (and greater)
### Added
- Added endpoint:
- POST `/session/{session id}/window/minimize` for the [Minimize Window]
- Added preference `extensions.shield-recipe-client.api_url` to disable
shield studies which could unexpectedly change the behavior of Firefox
- Introduced the temporary, boolean capability `moz:webdriverClick` to
enable the WebDriver conforming behavior of the [Element Click] command
- Added crashreporter environment variables to better control the browser
in case of crashes
- Added preference `dom.file.createInChild` set to true to allow file
object creation in content processes
### Changed

- Early abort connection attempts to Marionette if the Firefox process
closed unexpectetly
- Removed deprecated `socksProxyVersion` in favor of `socksVersion`
- Removed `ftpProxyPort`, `httpProxyPort`, `sslProxyPort`, and
`socksProxyPort` because _ports_ have to be set for `ftpProxy`,
`httpProxy`, `sslProxy`, and `socksProxy` using ":<PORT>"
- The `proxyType` `noproxy` has been replaced with `direct` in accordance
with recent WebDriver specification changes
- The [`WindowRectParameters`] have been updated to return signed 32-bit
integers in accordance with the CSS and WebDriver specifications, and
to be more liberal with the input types
- Mapped the [`FullscreenWindow`] to the correct Marionette command
- To make sure no browser process is left behind when the [`NewSession`]
fails, the process is closed immediately now
- `/moz/addon/install` command accepts an `addon` parameter, in lieu of
`path`, containing an addon as a Base64 string (fixed by [Jason Juang])
- [webdriver crate] upgraded to version 0.31.0
- [mozrunner crate] upgraded to version 0.5.0
### Removed
- Removed the following obsolete preferences for Firefox:
- `browser.safebrowsing.enabled`
- `browser.safebrowsing.forbiddenURIs.enabled`
- `marionette.defaultPrefs.port`
- `marionette.logging`
0.18.0 (2017-07-10)
### Changed
- [`RectResponse`] permits returning floats for `width` and `height`
- New type [`CookieResponse`] for the [`GetNamedCookie`] command returns

command, which makes geckodriver compatible with Firefox 56 and greater
- Linux x86 (i686-unknown-linux-musl) builds are fixed
0.17.0 (2017-06-09)
### Added
- Added endpoints:
- POST `/session/{session id}/window/fullscreen` to invoke the window
manager-specific `full screen` operation
- POST `/session/{session id}/moz/addon/install` to install an extension
(Gecko only)
- POST `/session/{session id}/moz/addon/uninstall` to uninstall an
extension (Gecko only)
### Changed
- Increasing the length of the `network.http.phishy-userpass-length`
preference will cause Firefox to not prompt when navigating to a
website with a username or password in the URL
- Library dependencies upgraded to mozrunner 0.4 and mozprofile 0.3
to allow overriding of preferences via capabilities if those have been
already set in the profile
- Library dependencies upgraded to mozversion 0.1.2 to only use the
normalized path of the Firefox binary for version checks but not to
actually start the browser, which broke several components in Firefox
on Windows
### Fixed
- The [SetWindowRect] command now returns the [WindowRectResponse]
when it is done
- Use ASCII versions of array symbols to properly display them in the
Windows command prompt
- Use [`SessionNotCreated`] error instead of [`UnknownError`] if there
is no current session
0.16.1 (2017-04-26)
### Fixed
- Read Firefox version number from stdout when failing
to look for the application .ini file (fixes [Selenium
- Session is now ended when closing the last Firefox window (fixes

Note that geckodriver v0.16.0 is only compatible with Selenium 3.4
and greater.
### Added
- Support for WebDriver-conforming [New Session] negotiation, with
`desiredCapabilities`/`requiredCapabilities` negotiation as fallback
- Added two new endpoints:
- GET `/session/{session id}/window/rect` for [Get Window Rect]
- POST `/session/{session id}/window/rect` for [Set Window Rect]
- Align errors with the [WebDriver errors]:

[`ElementNotInteractable`], [`InvalidCoordinates`], [`NoSuchCookie`],
[`UnableToCaptureScreen`], and [`UnknownCommand`]
- Removes `ElementNotVisible` and `InvalidElementCoordinates` errors
### Removed
- Removed following list of unused endpoints:

- [`CookieResponse`] and [`CloseWindowResponse`] fixed to be properly
wrapped in a `value` field, like other responses
- Allow negative numbers for `x` and `y` fields in `pointerMove` action
- Disable Flash and the plugin container in Firefox by
default, which should help mitigate the “Plugin Container
for Firefox has stopped working” problems [many users were
deleting a session
- Preferences passed in a profile now take precedence over
set of default preferences defined by geckodriver (fixed by
[Marc Fisher](
- The exceptions are the `marionette.port` and `marionette.log.level`
preferences and their fallbacks, which are set unconditionally and
cannot be overridden

- All HTTP responses are now wrapped in `{value: …}` objects per the
WebDriver specification; this may likely require you to update your
client library
- Pointer move action’s `element` key changed to `origin`, which
lets pointer actions originate within the context of the viewport,
the pointer’s current position, or from an element
- Now uses about:blank as the new tab document; this was previously
disabled due to [bug 1333736]( in Marionette
- WebDriver library updated to 0.23.0
### Fixed
- Aligned the data structure accepted by the [Set Timeouts] command with
the WebDriver specification

yet fully implemented in Marionette
### Changed
- [Synced Firefox
with those used in Mozilla automation

return an anonymous element by a name and attribute query
- Introduced a `moz:firefoxOptions` capability to customise a Firefox
- The `binary`, `args`, and `profile` entries on this dictionary
is equivalent to the old `firefox_binary`, `firefox_args`, and
`firefox_profile` capabilities, which have now all been removed
- The `log` capability takes a dictionary such as `{log: "trace"}`
to enable trace level verbosity in Gecko
- The `prefs` capability lets you define Firefox preferences through
- Re-introduced the `--webdriver-port` argument as a hidden alias to
### Changed
- `firefox_binary`, `firefox_args`, and `firefox_profile` capabilities
removed in favour of the `moz:firefoxOptions` dictionary detailed above

Firefox builds do not start with two open tabs in fresh profiles
- Disabled homepage override URL redirection on milestone upgrades,
which means a tab with an upgrade notice is not displayed when launching
a new Firefox version
0.10.0 (2016-08-02)
