That's odd. My experience with Firefox on Windows is that I can't get audio to work with Zoom. Jitsi, on the other hand, works perfectly though there is a small yellow box that warns me that I should use a "fully supported browser"
We use the Zoom standalone mostly. So Firefox isn't involved in the Zoom side.
Jitsi works fine with small groups. But if we have >10 Firefox users in a room it doesn't for us. Maybe if you have much better internet than we have or otherwise better resources it works for you?
We were using a WebRTC based tool before Corona (DFN), and had deprecated Zoom, unfortunately the people running that didn't manage to scale it up sufficiently in the crisis, hence we had to fallback to Zoom.
in Zooms webclient for audio to work with Firefox you'll need current Nightly, staged to be released as version 76 in May. Edit: another poster linked the bugzilla issue for AudioWorklets
