I've always wondered, why does Android forks of Firefox are not (or cannot?) get rid of ALL the trackers? Even Tor browser!
The browser with the least trackers is Mull, but it still has 1 Mozilla telemetry tracker, which the devs claim is completely disabled. I can't really read and inspect code, so I don't actually know.
So why is it? Does Mozilla make the browser unusable if you try to remove the tracker from the code?
Tor is a special case. They leave some stuff in tact because the average Firefox user would never touch that stuff and it would key tracking companies in MORE that the tracking stuff is disabled. Its called finger printing and part of what Tor tries to do is make everyone's fingerprints as innocuous as possible
