@gregtorn “collect and study private data”
where did you pick that up?
the studies are just simple tests for some new features. as an example DNS over https
they ship the feature and test in the background whether the connection to such a DNS server works.
none of your data is touched or delivered to Firefox.
also: you can disable the studies thing again (in-case you still don’t trust it) once the permanent fix is out
If you don’t trust Mozilla with studies, then I’m wondering why you trust Firefox? there’s not much of a difference here, it’s still just code by the same people
