We almost forgot the most important part!

After doing the above reset the NetworkManager with:

sudo systemctl restart NetworkManager

If you run your packet sniffer now (Wireshark/tcpdump) you shouldn't see anymore phoning home (from Connectivity Checks at least. Doesn't include DNS leaks, NTP, pings etc).

#phoneHome #NetworkManager #phoningHome

@schestowitz
#Mozilla now sell #advertising from the #Homescreen, how can we tell what data they are #phoningHome, eg are these adverts targeted etc.

That is a concerning development. And why we advocate the use of #TorBrowser (and #i2p) etc.
