> Edge user here. For one, chromium is faster than firefox, any given page will load about 20% faster,
I'm skeptical; You're probably measuring Chromium + ads against FF + ads.
The only fair test is testing agains FF + uBlockOrigin. And there, FF wins hands down.
I'm hardcore FF, and it used to be a bit slower than Chrome, but nowadays the difference is barely noticeable. And on very large pages (e.g. big tables), Chrome is a lot slower than FF.
