Firefox Wayland By Default On Gnome


Firefox is going to run natively on Gnome Wayland session and won't use XWayland/X11 Gtk+ backend by default. The XWayland/X11 Gtk+ backend can be still used via additional firefox-x11 package. This change affects Gnome only and won't be enabled for other Wayland compositors (KDE Plasma, Sway).

Current status

Detailed Description

Firefox with native Wayland backend has been available for last two Fedora releases as an optional package. It grown over the time and we can deploy it now as a default to bring all Wayland benefits to Fedora users.

Benefit to Fedora

Running Firefox natively on Wayland is generally faster and smoother on Wayland enabled sessions like Gnome Wayland and better supports HiDPI displays (respects desktop scale) .
