I use FireFox full time, but I think it's inferior to Chrome. It's uglier, slower and clunkier. I use it because although I'm more than happy to hand a lot of my digital life over to Google (and I'm really not a zealot about this), the ability to observe every single web site I visit ever and every interaction I have with those sites is just a bridge too far.

Prior to 60x I would agree, but nowadays I personally prefer the look and feel of FireFox. I haven't noticed any real clunkiness outside of Google sites like Gmail either. Chrome might still be smoother, but I haven't used it in over a year now, and I don't miss it. That's the key part for me, FF works well enough that I don't feel like I'm settling.

And I completely agree with you regarding ideological reasons to use FF. You don't have to be a zealot to value your privacy.
