Jitsi no longer works with Firefox after upgrade to docker image stable-4384

Hello all. I have been using Jitsi for the past few months and it’s been great. However, I recently upgraded my docker image and it seems like the compatibility with Firefox has broken. Last working image version is stable-4101-2. I used to be able to see other people’s video and share my screen, but now I just get a black screen. It seems to work fine on qutebrowser still.

I use my Android phone as a webcam and also enter the room with my real computer so I can see the other users’ video on a real monitor. Both devices are connected to my home wifi. I see some “Pair failed” lines in the jvb log - and interestingly they appear to be looking for the IP on my local LAN? Is this a new configuration issue or are there any known issues related to this with Firefox?

OS: Linux (Fedora 32)
FF version: 77.0.1 (64-bit) - fresh profile
qutebrowser version: v1.10.1

OS: Android 8.0.0
Jitsi Meet App version 20.2.3 (from F-Droid)
