@Linux_Is_Best @davidrevoy It's actually possible to configure firefox to make 0 spying requests and as a result, if you install GNU icecat or Tor Browser, you don't get spied on.

Auto update checking can be disabled on firefox, but I'm not sure about Brave or Vivaldi.

You will never get safety, security or privacy with proprietary malware.
