I'll be honest; I bounce between several browsers - Firefox, Chromium, Chrome, and even sometimes Edge, and sometimes it takes a second for me to even remember which one I'm looking at. Firefox is great for very specific work flows I have, but for a lot of other things, most other browsers will do.
Maybe it's because I tend to bounce around that I find it very interesting to hear that FF is difficult to use.
...and a lot that are not that independent. I never stopped using RSS. It's only because it's not so easily monetized that it's not more widely known, I bet.
