You can't switch to Firefox on iOS. It's Safari,or Safari with Firefox' UI. Apple forbids other web browser engines on iOS.

I realize that, but it doesn’t change the fact that with Firefox I don’t get ads on YouTube, whereas with Safari I do (ipad). FF probably just has additional content blocking features by default. Even when I install other content blockers on my device, safari still shows ads on YouTube.
