Which app for proxy settings?

I have the following problem: I live in a boarding school, in which one only by proxy into the Internet (over Firefox) comes. On the laptop / PC everything works wonderfully. The problem is that you can't set everything on the phone to use the Internet. I heard that there's an app?!

Is that correct? If yes, which? Does anyone know?
