I disabled any data collection using the GUI some days ago:
However Firefox still regularly tries to connect to this address incoming.telemetry.mozilla.org
, which is apparently blocked by my network.
Now my question - why does FF try to connect, what is it and how do I stop it?
It seems to have worked!
Firefox made these 5 connections:
telemetry-incoming.r53-2.services.mozilla.com push.services.mozilla.com firefox.settings.services.mozilla.com content-signature-2.cdn.mozilla.net firefox-settings-attachments.cdn.mozilla.net
…and then it shut up.
