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.
I got past it because it happened to throw a place from my country. And there was also a flagpole with a flag on it to really drive it home. XD
