Do you all run firefox without set any Environment Variable or do you chill it to run natively on wayland?
By default it seems still not working on wayland and always uses xwayland if i am correct?
You can check in firefox with about:support page …
can be forced set in .bash_profile
if [ "$XDG_SESSION_TYPE" == "wayland" ]; then
export MOZ_ENABLE_WAYLAND=1
fi
I use Wayand and was able to run FF natively without issue. I have since switched to Waterfox and no issues there either. Same story with ungoogled-chromium.
Setting $MOZ_ENABLE_WAYLAND all the way.
But it is probably more noticeable that FF looks “off” if you use fractional scaling.
That said it seems to be the default soon anyway: Firefox Is Going To Try And Ship With Wayland Enabled By Default … Firefox 121 is due for release around 19 December
So still needs to force it for now… was not sure
Only saw that if i do not set it to run on wayland itself i have per example only low resolutioons on yt videos… after force wayland i can get full resolutions in 1080…
Firefox? What about Xeyes? 
this is what i wanted to see anyway… so we do not need to do anyrhing only wait for it…as i was thinking aleady to set the option for Gnome installs…
Wow, what a novel concept, thx Wayland… 
must say this was on ARM… mali GPU thingy
This is how I do it:
To makes sure Firefox is using Wayland for Hardware Acceleration you can add the environment variable “MOZ_ENABLE_WAYLAND=1”.
In EndeavourOS:
(1) Make the environment directory:
mkdir ~/.config/environment.d
(2) Create the envvars.conf:
nano ~/.config/environment.d/envvars.conf`
(3) Add the following line to the ~/.config/environment.d/envvars.conf file:
MOZ_ENABLE_WAYLAND=1
(4) Reboot
(5) Launch Firefox and verify Windows Protocol is set to ‘Wayland’:
(a) Navigate to “about:support”`
(b) Look for “Windows Protocol” = wayland `

I’m using Firefox Nightly & it’s native Wayland…works very well for me…
Name Firefox
Version 122.0a1
Window Protocol wayland
Desktop Environment gnome
Thanks for this. It works on wayland for me now!
Perhaps these commands need to be put on wiki?
It is already 
Firefox with Wayland enabled is running great on my old laptop but kworker run up on my new laptop with FF. Looking forward to FF 121.
as far as we can see there will be no need to add it to the wiki… if it will get in default soon anyway.
we are on firefox 120.0.1 in repo and here:
https://archive.mozilla.org/pub/firefox/releases/121.0/
released on 18.12. (repo is also marked outdated already)
https://archlinux.org/packages/extra/x86_64/firefox/
2024 the year of wayland ? 
My Nightly Build is new:
Name Firefox
Version 123.0a1
Build ID 20231219152636
So 122 should be available early next year…
i do mainly use only nightly here anyway… but on i3 so no way to check wayland
I use way land since version 9x don’t remember which one, it has improved a lot since then and had being using it with a local firefox.desktop file to launch with wayland by default
Well—I’m a Gnome user & try to use beta software as much was possible…So I’ll try to chime in when the topic falls in my area…Have a Great Evening (or morning as it may…)
