While my experience is not the same (i use gmail, meet and youtube daily on Firefox with no issues), there's an easy solution to that - use Chrome for meet when you need to and use Firefox for all of your other browsing?
You describe it as an easy solution, but the easier solution is to just use one browser. Only one history record (which I use) and one set of plugins to maintain.
I've switched back to Firefox now that I no longer work somewhere that uses Google products.
I think New Meet performs a lot better in FF now, but Old Meet (with the gray action bar) had awful performance when I used it. The performance wasn't great in Chrome either, but it wasn't show-stoppingly slow like it was in FF.
I do that on mobile, I have a heavily locked-down Fennec F-Droid for random browsing but it's awful to use Google websites from it, so I keep Bromite around only for checking my old GMail / GDrive accounts (I've moved to other providers but they're useful backups). Doesn't make much sense to bother blocking Google Analytics and friends when I'm already using a Google website.
On desktop I don't have that problem, Librewolf works fine with Google websites for me, and I have a container set up for them.
At work we're on the MS stack so instead of Chrome I keep Edge as my other browser for Azure, Office, and Teams. I have to say, the vertical tab implementation from Edge is one of the best I've seen. Vivaldi's are fancier but they're not nearly as smooth, and Firefox's Tree-Style Tabs extension can't even compare.
