Okay, this made me laugh. "Proxys" and "proxie" You got it completely backwards, hahaha. It's "Proxies" and "proxy." Anyways... The best proxy there is is called Vivaldi, but for this to run on a school computer (with all it's locks and chains) you'll need to install it on a flash drive with a copy of firefox portable (portableapps.org [maybe .com], or just google it). I'm not going to walk you through it step by step because if you want to do this, you'll have to work for it. Good luck.
