Despite all their crypto bullshit and internal ad networks (which you can ignore/turn off), Brave mobile is great at blocking ads.
For instance ive never paid for YouTube premium to get rid of ads on mobile and allow background audio (yes they charge for background audio). On Brave mobile you can turn on background audio for all media and ive never seen/heard a YouTube ad.
Firefox mobile is great for this too. uBlock + sponsorblock + the fact that FF continues playing media when it's backgrounded make listening to long videos (like publicly recorded university lectures etc) a real breeze, it's a godsend if you like to listen to lectures while on long drives etc
Edit: ironically my post in this thread about how ads are partially enshittifying the internet, reads a bit like a sponsored endorsement for FF :-) ah well. It's still good.
