I had received an invite to a Teams meeting and opened it in firefox- esr. It showed the feed from my webcam in the preview, but when I joined the meeting, it did not let me enable it. I enabled media.webrtc.hw.h264.enabled and restarted Firefox; after doing this, I could enable the webcam in the call and it showed the output, but the caller said they couldn't see it.
Is this a problem with with my setup? I've used other distributions on my PC and not encountered this issue. I'm currently using Debian 13 with kernel 6.12.48+deb13-amd64 and Firefox 140.3.0esr. I'd prefer not to use the flatpak as I've never gotten that to work with KeepassXC.
