why does it open so many ports?
i understand add-ons open connections.. but why does FF itself need 8 ports opened? if i was hack i would def target these. TCP 1100 and upwards.. then i just piggyback on the traffic. There is no need for this many port openings. and every time you close their connection.. boom.. they reopen on a diff port range. This is a major vulnerability.
Chosen solution
Firefox needs to open ports to communicate with other Firefox processes.
You may see three or more Firefox processes running.
- one process for the main Firefox thread (user interface)
- one or more content processes set via dom.ipc.processCount
Options/Preferences -> General -> Performance
remove checkmark: [ ] "Use recommended performance settings" - one process for the compositor thread (Windows;graphics)
You can find the current multi-process state on the Troubleshooting Information (about:support) page.

If you are aware of a way to exploit those open ports, please file a bug report: https://bugzilla.mozilla.org/
To reduce the number of background connections, see: How to stop Firefox from making automatic connections.
