If a firewall is a good idea, where/how do i need to set up a firewall? (Sorry i'm not tech-savvy)
Also i noticed firefox has an addon for preventing webrtc ip leaks. Can that be used with tor?

You prevent IP leaks by using the tor browser bundle in its most paranoid security setting.
Enabling plugins will expose you to deanonymouzation techniques. Enabling a firewall does not help.
The reason the defaults are the way they are is for your safety. Do not change them unless you understand the consequences.
