> I run Firefox on my iPhone, it's free? Actually, you run Safari. Firefox and Chrome on iOS are just Safari with some different browser chrome. This happens because Apple has banned all other browser and JavaScript engines on iOS other than their own. Gecko, SpiderMonkey, Blink, etc are all banned on iOS. Mozilla isn't able to actually bring real Firefox to iOS because of this, and has to settle with a reskinned Safari parading around as Firefox in order to stay relevant. Same thing goes for Google and Chrome, it's just browser chrome on top of Safari's browser engine.
