There are other mobile browsers which incorporate adblocking directly (though not extensions generally).

The Einkbro browser, optimised for e-ink devices (as the name suggests) is one. I believe Brave does as well.

As much as I'm a fan of Firefox (using it now on desktop), on my mobile e-ink device, Einkbro's optimisations make for a vastly superior browsing experience.

There's also Kiwi browser which directly supports most Chrome addons and has for many years. I can never understand why it doesn't get more attention.
