When I launch Google Chrome I can see the following ports being used by the browser:

This is just from launching the browser.

How can I disable these ports in Chrome? I know my firewall is blocking these ports but how can I prevent/disable Chrome from even initiating these connections to/from ports 5228, 1900 and 5353?

I don't use mDNS, uPNP or push notifications.
