OK, I disabled widget.dmabuf-webgl.enabled but with no luck:

$ MOZ_LOG="Dmabuf:5" firefox
[Parent 2201: Main Thread]: D/Dmabuf We're missing DRM render device!
[Parent 2201: Main Thread]: D/Dmabuf nsDMABufDevice::Configure()

Also tested it on the clear Firefox profile to avoid conflicts with other
settings and the result was the same. 

So, the are two more steps to check:
- compile https://github.com/amshafer/nvidia-driver and check the results with
Firefox
- check how Firefox 103 handles NVidia's devices on Linux

I will try to make these steps and report the results here.
