Conversely, I use Edge for Google sites (and nothing else) because Google goes out of their way to make them unusably slow on Firefox. They look for polyfilled, unimplemented, or bugged features that see low usage, implement them in Chrome, and then make Gmail, YouTube, etc. depend on them so Firefox takes 20s to load.
I don't know your use case, but I can recommend one of the invidious instances to access youtube. There's a handy list on the formerly main instance https://invidio.us from which one can pick.
