Set wayland as default graphical server on wayland

Firefox

Use the XDG_SESSION_TYPE environment variable to automatically use Wayland natively instead of XWayland by default for better compatibility and performance on Wayland. This should still be able to be changed with MOZ_ENABLE_WAYLAND as it is now for people who need to run firefox through XWayland.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Yes, I agree. I think applications need to start trying to switch over to Wayland.

I really need to set the default graphics server to wayland because I have to use fractional scaling in Ubuntu 22.04, but using xwayland causes fuzziness.
