Hi,

It seems there is a Unique User ID in each FireFox install. This is how whatsapp can login again even without cookies. One can find in firefox BuildID ProductID ApplicationID EnrollmentIDs and about 32k more of telemetry data (see crash info), incl plenty of detailed hardware and software info that creates a fingerprint of the user. Who had that horrible idea?

This is VERY disconcerting given that you laud yourselves as privacy protectors.

Please explain why you collect all that data.
