Built from 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.

  • Android:

    Marionette will only be enabled in GeckoView based applications when the
    Firefox preference devtools.debugger.remote-enabled is set to True via
    moz:firefoxOptions. This will be fixed in the Firefox 90 release for Android.

    In some cases geckodriver could crash due to a stack overflow when handling
    certain device errors.

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
    GeckoView.

    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
    application.

    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
    system.

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.
