I'm currently using firefox and thinking of switching, would love some more features and a better aesthetic, but I'm interested in what others are using!
I'll be honest, not a lot of pros to using Firefox if you don't care about using the best adblocker (uBlock origin). That said, if you haven't tried it recently, you should give it a shot. I would recommend installing uBlock Origin and Dark Reader (if you like your pages dark) for the best experience.
It's not as fast as Chrome (not noticeable on newer devices) but I personally disagree with giving Google so much power over the web, so I'm ideologically opposed to using anything based on Chromium or not open source, so my options are limited.
