This is Fennec, a fork of Firefox for mobile, though mobile Firefox has this same menu. c: Extensions are very much supported on mobile and it’s great.
Though I should add: I’m not an iOS user, so the story is likely to be different there, Apple being Apple and whatnot.
The scene with the guy without eyes and a tongue is imprinted into my mind because I happened to look at the TV just as that happened. I don’t even remember how old I was, but definitely way under 10.
