Known problems

• Firefox running in Linux Sandbox (e.g. Snap package):

  Using geckodriver to launch Firefox inside a sandbox -- for example a Firefox distribution using Snap or Flatpak -- can fail with a "Profile not found" error if the sandbox restricts Firefox's ability to access the system temporary directory. geckodriver uses the temporary directory to store Firefox profiles created during the run.

  This issue can be worked around by setting the TMPDIR environment variable to a location that both Firefox and geckodriver have read/write access to e.g.:

  % mkdir $HOME/tmp % TMPDIR=$HOME/tmp geckodriver

  Alternatively, geckodriver may be used with a Firefox install that is not packaged inside a sandboxed e.g. from mozilla.org.

• macOS 10.15 (Catalina) and later:

  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

• Users with the Rust toolchain installed can now build and install geckodriver from crates.io using Cargo:

  % cargo install geckodriver

• Support for Get Element Shadow Root

  Implemented by David Burns.

  The standardised WebDriver Get Element Shadow Root endpoint provides a way to retrieve the Shadow Root of a given web element. This endpoint is supported by geckodriver when using Firefox version ≥96.

• Support for additional hosts and origins

  Users can now specify a list of allowed Host and Origin headers for incoming requests using the --allow-hosts and --allow-origins command line options, respectively. When such a flag is provided, exactly the given values will be permitted.

  By default any request with an Origin header is rejected, and only requests containing the bound hostname (specified via --host), or an IP address, in the Host header are allowed. These configuration options are designed to support scenarios where geckodriver is running on a different network node to the host e.g. some container based setups.

Fixed

• Geckodriver lets Marionette itself select a system allocated port, so that it's no longer required to specify a fixed port when using a custom Firefox profile. This is done by reading the MarionetteActivePort file of the Firefox profile in-use. This helps to avoid port collisions when multiple Firefox instances are run in parallel.

• It's no longer possible to specify both the androidPackage and binary capabilities togther within moz:firefoxOptions because these capabilites are mutually exclusive.
