Damit werden Benutzeraktivitäten und Daten an Remote-Server übermittelt. siehe https://github.com/NanoAdblocker/NanoCore/issues/362 „Die Erweiterung ist nun so ausgelegt, dass sie spezifische Informationen aus Ihren ausgehenden Netzwerkanfragen nach einer extern konfigurierbaren Heuristik sucht und an https://def.dev-nano.com/ sendet.“
