webcam in firefox on pinebook pro

I wonder if anyone has the webcam working properly in a browser for the pinebook pro yet? I can access it without any problems using mpv, but it doesn't seem to be accessible in firefox. Running the tests at

https://webcamtests.com/

indicates that "your webcam shows a one color filling". The same site works fine under stock debian. This is with sway, running the latest mesa-git, FWIW.

Thanks for any help!

So, the issue is still present in the latest firefox. It doesn't seem to affect chromium. I found reports of a similar issue in the Phronix forums. Again, the camera works in firefox on Debian. Does anyone have any suggestions about where to file a bug report?
