In the latest Fedora and Ubuntu releases, and presumably any derivatives thereof, ship Firefox on Wayland. They don't use the compatibility layer XWayland, but rather actual Wayland using our pref MOZ_ENABLE_WAYLAND to force it on. Right now we are unable to test this configuration in CI because our version of Ubuntu is too old to work well as Wayland development is quite active. We don't need our existing tests on Linux to be fully ported, but it would be good to have the option to run some tests using Wayland on a newer Ubuntu, such as 21.04. This would allow us to start greening the tree for Wayland, and push it out officially from our side.
