Ahead of tomorrow's official release, the installation files for Mozilla Firefox 121.0 have been released, which brings the most exciting Christmas gift to Linux desktop users: Wayland support is enabled by default. Firefox 121 is ready to allow Wayland support by default on modern Linux desktops, instead of defaulting to XWayland.
Some Linux distributions and package builds have been using native Wayland paths for some time, but it’s now great to see upstream builds making this change by default as users prepare to start the 2024 Linux desktop.
Firefox 121 has been tested by users on Wayland and performed well, and X.Org/X11 support remains for those who do not use a Wayland-based desktop environment.
Firefox 121 also adds voice control command support on macOS, adds the option to always force links to be underlined within websites, Firefox now includes a floating button to help create in PDFs, adds various CSS features, and other developer enhancements. Firefox 121 also now supports tail call elimination in WebAssembly to enhance support for functional languages.
For those who want the last major Firefox update of the year, Firefox 121 is available to download now from archive.mozilla.org:
