I’ve been using Firefox for years now and the only issue I’ve had is that at work I can’t download particularly large files from John Deere operations centre so I use another browser just for that. Everything else, which is literally everything as far as I’m concerned, has been a better experience for me than Chrome ever was. Also Brave uses chromium which is cringe.

I’d say it’s worth the switch as if you care about privacy, Firefox just has more tools available to this end
