I love Firefox. It just doesn't always feel like it loves me back.
I use Firefox and I like it (especially being able to use uBlock Origin), but I really dislike what Mozilla has become over the last ten years or so. I think that's the key distinction, I can mostly manage Mozilla's crap by turning off a bunch of stuff in my Firefox settings, but I think it's really important for the web to not use a Chromium based browser.
Same. I want to love Firefox, but it does not have the polish on Android compared to Chrome-based browsers.
Not like Chrome, Chrome feels like it LOVES hanging out with me, looking over my shoulder, telling all it's friends about what I'm working on, what I buy, and how much money I make.
