Startup hang with Firefox running in a container (e.g. snap, flatpak):
When Firefox is packaged inside a container (like the default Firefox browser
shipped with Ubuntu versions since 22.04), it may see a different filesystem
to the host. This can affect access to the generated profile directory, which
may result in a hang when starting Firefox. Workarounds are listed in the
geckodriver [usage documentation].
Added
Added full support for the Web Authentication specification.
Requires Firefox 152 or later.
Added support for the Global Privacy Control specification.
Requires Firefox 147 or later.
Added support for the unhandledPromptBehavior.file capability, which controls
how file dialogs are handled during automation.
Requires Firefox 147 or later.
Changed
Firefox on Android now detects early exits during startup, preventing
geckodriver from making prolonged connection attempts to a process that
has already terminated.
On Linux Snap installations, geckodriver now launches Firefox using
the direct binary path, improving compatibility with containerized
environments.
The implicit and pageLoad timeouts now accept null as a value,
which disables the respective timeout.
When the Android test runner fails to start, geckodriver now
automatically retries the launch once before reporting an error.
When geckodriver is terminated (e.g. via SIGTERM), it now attempts
a graceful shutdown of Firefox first, falling back to a forced kill
if necessary to avoid leaving behind orphaned processes.
Invalid files encountered when extracting a custom profile now
raise an error.
Updated geckodriver to the Rust 2024 edition.
Fixed
Fixed an issue where an already running Firefox package on Android
was not correctly force-stopped before launching a new session.
Fixed retrieval of crash minidump files from the Firefox profile
directory.
Removed
Linux 32-bit builds have been discontinued.
Starting with Firefox 145, Mozilla no longer ships binaries for 32-bit (x86) Linux. As a result, geckodriver binaries for that platform are no longer provided either.
If you still need a 32-bit Linux build of geckodriver, you can install it via cargo install or cross-compile it yourself:
cargo build --target i686-unknown-linux-gnu
Removed FTP proxy support from WebDriver capabilities, as FTP
proxying is no longer supported by modern browsers.
Removed the deprecated --enable-crash-reporter command line argument.
Use the MINIDUMP_SAVE_PATH environment variable instead to preserve
crash dump files.
