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?
Well, if you're interested to determine what is causing activity when the system is supposedly quite then yes.
Restart the system, wait a while, check your ksysguard as you did before and then check netstat and/or iftop.
FWIW, I look at this as a chance to learn "troubleshooting" techniques. Nothing sinister is going on.
