I thought you said your system was "quiet"?
For your "network activity" issue the lines of interest are those which include "ESTABLISHED" as the state.
It shows both "thunderbird" and "firefox" are both running and connected to hosts. So, one would expect some network activity
When I opened the thread this morning (hours ago), my system was quiet. When, several minutes ago, I did the netstat -atuevp whose output I attached to my reply to you and Tim, yes, Thunderbird and Firefox were running.
Shall I reboot and re-do the netstat before launching Thunderbird and Firefox?
I will dig into the user-guide you referenced. This will take time.
Oh, with the output of netstat, if a process has made a connection but then disconnects the state may not be "established" but changed to "TIME_WAIT". If I recall, it will remain in TIME_WAIT for around 60 seconds before the connection is torn down.
So, best to check netstat just after you see activity has occurred.
