Because Firefox on mobile is a pile of shit to be honest. It works great on desktop, but the mobile experience is subpar. For a chromium browser, Bromite used to be an option, but it seems abandoned now. Brave is one of the few Foss chromium browsers left that also supports adblocking.
I can’t think of a reason why anyone would use a browser other than Firefox and its forks.
