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.
There are two "Firefox"s:
The codebase remains open source under the MPL while the binary explicitly, by Mozilla’s own admission, is not. They are source available.
From the very brief skim I did of your post, it looks like we’re on the same page. I had a few people who don’t understand open source licenses come at me in my Lemmy replies when this was first unfolding. Ultimately it’s on them to understand their agreements.
