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.
Mozilla seems to not be able to do anything good. No matter what decision they take, it will be perceived as a bad one by some vocal segment of the community.
