Using Chrome with "Strict site Isolation" enabled.
Chrome is by far, the most responsive browser I have tried on Android, though it needed something to stop the full screen ads. Strict site isolation slowed this down, but did not stop them, then came along their built in ad blocker, and while it still allows a lot of crud, it has finally stopped the full screen ads. I should mention, I am very careful as far as surfing habits go, and was seeing these ads on legit sites.
Personally, I would like to see Google do away with this excuse of conserving memory as to why they will not implement extension support. I would definitely give it thumbs up all the way if they did.
