I’m not going to enumerate them, mostly because I did not keep track of which one was on and which one was off before messing all of them up. If you’re curious, open “about:config” and search for “survey*.enabled”, “collect*.enabled”. Even with all settings disabled, some of them remains on, and they do cause traffic to the (documented) endpoints.

Yes, you can disable the settings that are exposed to you with a checkbox. How about all the other that have no checkboxes and you can find by snooping around in either the code or about:config ?

I have not dug too deep into it for now (especially if I end up changing browser), but even with everything in the preferences disabled, examining the content of about:config gives a lot of telemetry.whatever.enabled left to true, sometimes with names that do not seem to match any option given to the user. That’s not a good look either.

Yeah. And their privacy notice is basically a mix-match of ten or so sections that have no place in a web browser privacy policy, that allows them to do the things people reproach them for doing.

It’s like saying “we’re not doing that, because we’re limited by that document that allows us to do just that”. And now they’re tripling down on it.

if it’s properly handled and anonymized it benefits everyone using firefox

glub glub much?

There is no justification for opt-out telemetry data collection, and there is no proper handling of data obtained despite user pushback. Also, properly anonymizing large data sets is not as trivial as you think. Even “fully anonymized” data set, assuming everything’s possible’s been done, can lead to correlation when added with other data. Even “cohorts” can lead to the creation of an aggregate group with so few individuals that it basically boils down to individual tracking.

Why do you think people are so vocal about not letting any of this happens in the first time? It’s not for blind idealism. It’s basically because even a minimum waiver on “supposedly anonymous” data is a huge blow to your privacy. And some people care about that.

Besides, Mozilla’s been pushing for a shitton of features that are constantly blamed for Firefox becoming as bad as its competition, and constantly turned off/removed. If they cared even a tiny bit about user feedback, the last… 3, 5 years of decisions from Mozilla would have been very different. Feature usage telemetry is a joke to make people accept their bullshit; the only thing that influence feature development is management or very heavy pushback, and that happens in dev issues, not with telemetry feedback.

It’s slowly turning, too. Start looking for something else.
