Yes it can. 

As for Chrome, there were blog posts discussing that Chrome is the most tested 
and recommended due to simulcast being enabled and stable. That was from a 
while ago, so things may have changed. I know they planned on moving to a more 
unified approach at some point, but I don’t know if they ever did it. We always 
use the latest available in the jitsi repo, so there may be features and 
support I am unaware of. While they stated Chrome, they probably include 
Chromium based browsers in that as well.
