Before the official release tomorrow, Mozilla Firefox 121Version 0 of the installation file has been released, and it brings the most exciting Christmas gift for Linux desktop users: Wayland support is enabled by default. Firefox 121 is ready to allow Wayland support to be used by default on modern Linux desktops instead of Xwayland by default.
Some Linux distros and package builds have been using the native Wayland path for a while, but it's now nice to see that upstream builds make this default change when users are ready to start a 2024 Linux desktop.
Firefox 121 has been tested on Wayland and has performed well, and for those who don't use a Wayland-based desktop environment, Xorg x11 support is still there.
Firefox 121 also adds voice control command support on macOS, adds the option to always force links to be underlined within **, Firefox now includes a floating button to help create in PDFs, adds various CSS features, and other developer enhancements. Firefox 121 now also supports tail call elimination in WebAssembly to enhance support for functional languages.
For those who want the last major Firefox update of the year, it's now possible to download the files from Archivemozilla.org **firefox 121：
