Override banned ports in Firefox about:config

Sometimes you need to allow an incoming connection through a specific port that Firefox is blocking. You can override this by following these steps:

1. Open Firefox
2. Type this into in the address bar: about:config
3. Accept the fate of your Firefox warranty
4. Right-click on the window
5. Select: New>String
6. Enter the preference name: network.security.ports.banned.override
7. The value will be the port you want to open for your browser (you can open it all of the way by entering 1-65535... however, I don't recommend this)
8. Test it out
