What ports does Mozilla Firefox use to acess the internet?

What ports does Mozilla Firefox use to acess the internet? The application itself, not websites. My router is blocking Mozilla Firefox and I don't know what ports to foward. Thank you.

1. The only one that is connecting your computer to the internet.
2. its standard port 80 could be your firewall is blocking the application rather than the port
3. None, as far as your router blocking any. The router only blocks incoming requests, and your browser only makes outgoing requests. Forwarding a port is for incoming requests - someone trying to connect to your computer. There's no such thing as forwarding an outgoing port. You evidently have a problem of some kind, but it's NOT the need to forward ports. (Since Firefox doesn't listen on any port, it can't get an incoming request, even if you didn't have a router.)
