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.
Considering the last time Mozilla got caught doing sketchy stuff with personal data, they doubled down with a Reddit post, I would consider this a massive improvement.
