I make my kid use Edge just so I can see how good it's doing against other browsers (Hahahaha, this sounds like a real shitty thing to do now that I say it aloud). It's fast, I've never seen it crash. I could use it and live a fulfilling life. Whatever...
I'm fundamentally dependent on Chrome because Join lets me text from my desktop with it. If you're using Signal, on desktop it's a Chromium plugin. Chrome's a pig - it's a big, fat crashy pig. But until someone comes up with a decent desktop MMS interface, I'm stuck with Chrome.

Not sure if it properly does MMS, but it's worth a try. I've gone Firefox earlier this year and haven't looked back. Solid, stable, fast. UI is kinda wonky IMO but not unbearably so.
