As a Firefox user, I'm not completely surprised. There are multiple video call applications I tried to use that didn't work on Firefox (on Linux at least). I personally have Chrome installed for the sole purpose of resolving those situations and go right back to FF. I'm scared though for FireFox, because they aren't doing too hot. I don't want a Google dominated web. Having the only two real web competitors be Apple and Google is a terrifying idea. Hell, it doesn't event have to be FireFox, I just want some more competition, but browsers are so complex at this point that I don't think we can ever get to that point.
I hear you, I've been working on peercalls.com, a video conferencing app, for the past few years and it works on all major browsers and platforms, including Firefox.
That said, I'm bummed out that E2EE using insertable streams / SFrame transform is only currently supported in Chrome.
I've also noticed that very few devs in the WebRTC community actually test stuff in Firefox.
