Device information

...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)”
