On: Firefox Focus – A new private browser for iOS and Android

[Manishearth]

Firefox is very judicious about collecting data.

https://wiki.mozilla.org/Telemetry/FAQ

It collects things like "how slow is rendering" or "do you use feature X?". It's all anonymized, and you can verify this from the source (you can also turn it off). Folks are very careful if adding new telemetry metrics.

This isn't trackable data.
