I use Firefox almost exclusively.. However there are some websites that I've made purchases on that straight up don't work with Firefox, in which case I'll use Edge :(
I'm going to listen to you; I'm going to use Firefox. My problem has always been that it's hard for me to use non-Chromium based browsers, but I'm up to the challenge.
Ungoogled Chromium is a cool project I highly respect, but I think we're at a point where no browser using Chromium can be called ungoogled in good conscience anymore.
