I've been running Nightly and experienced the same thing with inbox. If I attempt to interact with it before fully loaded, inbox will freeze up for minutes at a time. Love everything else about nightly, this is my biggest issue.
Seriously, when we talk so much about the Web's portability, why is a major feature from a major website not even working on identically on the two biggest browsers? Since it's Facebook we can't accuse them of browser favouritism as they're browser neutral. I wonder what APIs are missing from Firefox that makes FB Live Video broken?
> Favoritism isn't the only reason for these things. What often happens is that the website devs all use one browser and nobody tests it.
That is exactly the point the GP post makes. These things are supposed to be standardized and the standards well described, so basic things should work everywhere without any testing. But somehow for web, it is acceptable and accepted as status quo, even after years and years of smashing our heads against the wall of nonstandard, browser-specific features.
Works in Nightly but the video quality is beyond garbage. 1080p webcam should not look like 320p. Chrome properly sees my camera resolution and uses it.
It's always a good idea to back up your profile first (where your bookmarks/passwords/etc. live), especially when downgrading:
