Issue
unable to use my webcam in firefox with mozilla test mozilla webrtc demo
The only cameras available are a long list of ipu6 camera in firefox.
The camera is working when using this command qcam -s "width=720,height=520"
Tested with empty firefox profile.
It used to work with fedora 41. but since the upgrade to fedora 42, no camera in firefox.
