Firefox on mobile caters for extensions too. Not having ads or tracking on your phone is great. FF on both mobile and desktop is fantastic tbh.
Firefox Focus is also a lovely little mobile browser for random queries and such. It’s effectively always in private browsing mode; anytime you close it, it clears its cache.
I definitely use it more often than “regular” Firefox on mobile. I only really use regular Firefox if I need some sort of persistence or login.
Doesn’t have sponsorblock though unless you use nightly and make some tweaks
