I switched from Chrome to Firefox 6 months ago when Google started playing games with it's ad blockers.
All of my Chrome extensions and features were supported by Firefox and I was a happy camper.
Then two problems got to me:
1. Slow performance on web apps like Gmail (use it for work)
2. Firefox regularly crashes (more than 10 times per day)
I'm trying to switch to the Brave browser (Chromium) now, but I was almost a Firefox convert.
