Telemetry can't be disabled #4

Steps to reproduce

Disable all three options in Data Collection header in Settings
Use any Firewall/Web request logging app to see it's still sending data to mozilla at incoming.telemetry.mozilla.org

Expected behavior

Stop sharing Telemetric Data

Actual behavior

It does not stops sending Telemetric data

Device information

  • Android device: AOSP v10
  • Fenix version: v80.0.0-beta.6
This bug was intentionally made by Mozilla and is present in Fenix official app also Unfortunately android network logging apps are no so advanced I can only see that connection is being made to incoming.telemetry.mozilla.org

Mozilla does not respect user requests to stop tracking telemetry data

Didn’t I opt out of Firefox studies when turning off telemetry?

When turning off telemetry in Firefox’s privacy preferences (about:preferences#privacy) you need to uncheck the following three boxes:

  • Allow Firefox to send technical and interaction data to Mozilla
  • Allow Firefox to make personalized extension recommendations
  • Allow Firefox to install and run studies

So even though a telemetry-disabling user explicitly tells Mozilla that they don’t want to “Allow Firefox to install and run studies,” Mozilla goes ahead and runs a study on telemetry coverage using their system add-on.

...

The good news is that it is possible to turn off telemetry-coverage if you are one of the lucky 1% selected to have it installed. To do so, you need to manually create a preference to opt out of Firefox telemetry antics a second time. Information on how to do so isn’t so forthcoming, either. It’s buried in the bugtracker for the telemetry-coverage system add-on but has been tested as working by Mozilla’s devs:

“The only other thing to test here is that this extension has a special boolean opt-out pref: “toolkit.telemetry.coverage.opt-out”. This pref does not exist by default and must be created, if set to true then the extension should not send a payload as above for users in the 1% sample (such as the Telemetry client ID above will be)”
