Comment (by anarcat):

 also, on linux jitsi eats CPU like crazy, apparently because it doesn't do
 hardware acceleration. this reddit thread has some more information:

 important quotes:

 acceleration. Haven't noticed it in the windows side

 are running a patched version of chromium with va-api added.

 AFAIK, no upstream support looks like it will be added soon.

 Firefox particularly has problems working with Jitsi and WebRTC because of
 missing features.

 They (Jitsi) did improve their support for non-chrome browser, apparently:

 Jitsi are also working on E2E encryption but that requires "insertable
 streams":

 In general, here are the issues tagged with jitsi in the firefox
