TL;DR: With Firefox 56, Mozilla combined Firefox Health Report and Telemetry data into a single setting called “technical and interaction data”, which was then enabled by default. This data was then shared with advertising partners on a de-identified or aggregated basis.
Well shit. I left telemetry on because I liked Firefox and didn’t mind helping the developers with their free software. I very much mind helping marketers. I’m really curious what exactly is being shared.
But I’ve already moved on to Waterfox and Librewolf on everything but my phone.
Same. If you don’t enable telemetry, how are they supposed to know if a feature is popular?
Meanwhile, they’re selling the data to fucking ad networks. Scum.
Put Waterfox on your phone! It’s been great for me.
