Earlier quoted context omitted.
My child's school uses Google Classroom. The Google experience is unusable in Firefox. Meet doesn't work (e.g. he sees nothing when the teacher screenshares). This seems really quite anti-competitive. My child cares about privacy and switches browsers. Chrome for Meet, Firefox for most non-Google things.
Something is wrong with their system then. I use Meet in Firefox and it works. Sometimes it's buggy but I can always get it to work.
For a work tool, this is a problem. I get reports of fuzzy microphones, audio that slowly descends into robotic noise and screenshares that don't in Firefox. So I switch to Chrome for Meet in work, it just looks bad if my meetings don't work like 10% or more of the time.
I'm sure this is a problem with Google more than Firefox, given I have none of the same issues with discord in firefox on my personal devices
