[Thorin-Oakenpants]

so firefox is making data collection opt-in by default?

It’s listed under the telemetry section, and telemetry has always been default opt-in (with new profiles loading a privacy/telemetry related tab to inform users etc, so they can opt out if they want to - plus it’s always in the UI - it’s not hidden or anything). It has to be opt-in, and has always been opt-in, otherwise their dataset would be tainted, small, not-real-world and about as useful as a peacock in a knife fight (because IDK 95% of users won’t change anything)

BUT … the form you’re quoting is actually the standard form for adding telemetry items and has nothing to do with overall telemetry - i.e they are adding a telemetry item to measure opt-in/opt-out rates of the new telemetry UI option

---

The Learn More link is dead, the prefs are default false - so until they land it, we don’t need to worry about it - that and I can’t find any documentation (there’s a jira link but I can’t log in), and I’m slightly confused, since related tickets/talk are about changing PB mode to dark mode (how does that fit in with telemetry?). I used my guggle search ninja skillz and couldn’t find out anything more about “Privacy Segmentation” - I’m sure we will all know about it sooner rather than later, via a Mozilla blog or that Learn More link

Anyway, my best guess, once they roll this out, there may be some sort of notification on update (or else why the telemetry on opt-in rates?) - and if anything, provides more privacy options for end users. And, any data collection would still respect the master telemetry pref IMO.

tl;dr: non-event

I am missing you too guys.
