Jitsi-meet: Documentation: add Firewall ports to be open for Firefox to work

[rosa2]

Is your feature request related to a problem you are facing?
I do face to face classes and with the Coronavirus I am trying open source video-conference programs. I have many problems with Firefox browsers and Jitsi, so I have been searching. I found 2 main reasons for Firefox no to work:

• Implementation of WebRTC that Firefox developers are fixing https://bugzilla.mozilla.org/buglist.cgi?status_whiteboard_type=substring&status_whiteboard=jitsi-meet&list_id=15179616

• Ports that are not open in the server (as in this article explained)
  _Firewall: If her outgoing network connections with a desktop or Netzwerk-Firewall filter, you should release the ports TCP-443 (HTTPS) and UDP-10000 (video Stream)._

Describe the solution you'd like
For the second problem, please, add in your installation instructions to open those ports.
As for example in
https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md

Also, find a way to tell people when they update their installation.

Thanks a lot for this great tool :)

For the second problem, please, add in your installation instructions to open those ports.

There's a patch here for this which can be integrated by anyone who has signed the cla (I relinquish any rights on the content).

Thanks a lot @dbuenzli and I understand why you don't sign a CLA. I too much prefer a CDO :)

I've created a new pull request using dbuenzli's changes, as I don't like the CLA but have signed it.
