On a perhaps related note, I have noticed that a Google Meet that consumes just over 1Mbps on Google Chrome consistently consumes close to 4Mbps on Firefox. Same settings, same window size, same participants. I cannot help but wonder whether Chrome has implemented some standard browser feature more efficiently, or whether it has special native features just for Meets.

Change your useragent to Chrome. Google often gates performance improvements to be Chrome only.

Or they're using a different codec which is not supported by Firefox.
