I'll ask what extensions you use on your Firefox, because I regularly use Google Meet on an 2014 MacBook Pro with latest Firefox, and it doesn't even make the fans spin, plus all the goodies like environmental noise cancellation is there. Meet team also recently ported some of the Chrome only features back to Firefox, due to some fear, I guess...

The YouTube videos in higher bitrates (like 4K) is generally due to Firefox's ability to hardware accelerate things, and there's a bit of difference there, yes. But on Linux and macOS (moreso in sequoia), I see no extreme CPU use. Just testing it on Firefox 132.02 on Debian Testing with Radeon 550 with open drivers, While I see a spike in CPU load, there's definitely some GPU load is also being produced, pointing to at least some GPU acceleration.

On the other hand, Intel N100 with on board graphics can visibly struggle at 4K as far as I can tell. That one runs Firefox ESR though, I need to retest.

I don't use WASM based Google Workspace tools (docs, sheets, etc.) heavily, but they don't crash when we use it on other pepople's documents that we collaborate on.
