What version of Firefox? What OS? Can confirm Firefox-dev on Linux has no workin...

Firefox 74.0 on Fedora works.

AFAIK Firefox on GNU/Linux uses Gstreamer. Maybe you need to install gstreamer codec packages.

Update: Firefox switched to FFmpeg and removed Gstreamer support some time ago. I have FFmpeg installed from rpmfusion, but I don't know if that's relevant to WebRTC and Jitsi.

Looks like 2020 is still not the "year of Linux on the desktop"

(from a desktop Linux user years 1996-2004)

Firefox preview on my phone in desktop mode worked FWIW.

If that's on iOS, you're not actually using Firefox since it uses Apple's Webkit.

Firefox preview is only on android.

iOS doesn’t support videoconferencing in the browser - you have to download the app.
