I am having a hard time reproducing this issue.
Can you help in expanding the steps to reproduce a little? I might be mistaking.

1. Download Release v81.0.2.
2. Open build folder in terminal.
3. input:
   MOZ_ENABLE_WAYLAND=1 firefox
   and tap ENTER.
4. check about:support

I may be hitting another issue because, believe it or not, I am seeing version v82.0 on a v81.0.2 build if I open with it with MOZ_ENABLE_WAYLAND=1;
and I see 81.0.2 if I open it normally.

Can you please correct my steps to reproduce?

Thanks for picking this up :)

I don't have the resources to effectively compile firefox myself so i use the Nix package manager (but I don't think it matters much) and my steps are:

1. install firefox 81.0.2
2. MOZ_ENABLE_WAYLAND=1 firefox
3. see in about:support that it selected "wayland/drm"
4. upgrade to firefox 82
5. MOZ_ENABLE_WAYLAND=1 firefox
6. see in about:support that it has selected "xwayland"

I am having the same issue on openSUSE Tumbleweed. It was fine while I run "Full Wayland" session but because of massive incompatibility issues I selected "Wayland" session instead. Wayland is available as I can see from KDE System Information. I have put MOZ_ENABLE_WAYLAND=1 to /etc/environment and just to make sure I have tried 'MOZ_ENABLE_WAYLAND=1 firefox' in a shell. No change at all. This is Firefox 88.0.1 on openSUSE TW.
