How do I enable plugins so I can use Tor to see sites that require plugins, and how do i prevent IP leak?

Question

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?

Answer 1

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.
