I used to love using firefox, and I still do on my desktop/laptop. The mobile version, however, is unusable for me. Everytime I switch the screen and try to go back to the browser it refreshes the page. This makes it impossible to do so many things that I would consider basic functionality at this point (2fa, passwords, etc.). You can't even go into about:config to change options to try and fix it. Other browsers may be less extensible or privacy centered but they at least work.
