No GL in Firefox 121 on Linux
Recently upgraded to a new laptop, Thinkpad X1 Carbon 11th gen. Running a Wayland-based WM. OpenGL is working fine everywhere except Firefox. Works fine in Chrome, Blender, glxgears, Steam games. Firefox 121 gives the following error:
[GFX1-]: Failed to compile vertex shader: gpu_cache_update [ERROR webrender::device::gl] Failed to compile vertex shader: gpu_cache_update
Confirmed that MOZ_ENABLE_WAYLAND=1 is set.

Ok, I realized I was using an unstable package in NixOS. Reverting to stable resolved the issue. Apologies, will close.

Steps to replicate?
1. Launch firefox from the command line 2. Notice error on the console 3. Try out a website with GL, e.g. https://alteredqualia.com/three/examples/webgl_pasta.html 4. Note error in the browser: Your graphics card does not seem to support WebGL. Find out how to get it here.
The exact version of Firefox is 121.0.1 by the way.

Enter about:support in the address bar and examine the Graphics section. There's info about WebGL support.
