I also went completely to FF on my phone the moment it had uBlock Origin and some other extensions. Now that I learned how to force other ones, it has been game over for other browsers aside from just seeing how they are every now and then (I work with general public and need to be aware of how they work). The only thing I would really really advise in addition to FF on a non-rooted device is setting the Mullvad ad-blocking/tracking blocking DNS for the device.

It helps even if I need to use a different browser (not as good as also having uBO), and has really good chances of blocking ads in many apps. For example, I kind of treat the Microsoft Solitaire app since it keeps games and stats from my PC. However they have lots of video ads that play after a couple of games. With the DNS it just kind of glitches when an ad should run and just goes on to the next round instead. The only odd thing I see with other apps is that it can cause my bank app to take a little longer to load when signing in (I am guessing due to tracking it is trying to do). But after like ten seconds it goes through like normal.

This is the DNS address to add if you want:

https://base.dns.mullvad.net/dns-query

And here is the main site for all their options and tester to make sure whichever one you pick is working:
