Google still tries to sabotage Firefox experience on Google Apps, especially Meet but also YouTube and sometimes Google Sheets/Docs as well.

They want to degrade the experience just enough to get you fed up with FF and go (back) to Chrome, without making it absolutely obvious that's what they're doing.

They often label these things as "regressions" because they don't test on Firefox and take forever to fix them. But I can't help but believe it's intentional.
