Starting in Firefox 138, Mozilla started gating Firefox Labs features behind data collection.
Mozilla had announced that some new Firefox features would be released via Firefox Labs.
It is now a few hours since I posted, and there is reason to celebrate – Mozilla is updating Firefox Labs to let people access features without needing to enable data collection.
I agree that there’s a change in that it’s now publicly communicated that it’s not an ideal end state to tie Labs to whether telemetry is enabled, but that might just as well have been the case in the first place - just not communicated publicly. (If that is indeed the case, then of course ideally that would have been explicit somewhere immediately, but alas.)
