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.
The Nimbus migration is literally why it was kept behind telemetry for a couple days, that’s not a red-herring. You’re attributing malice to neglect - which is now fixed.

It is, just check their blog a bit back
It’s not a couple of days, it is in place today. We need to wait until new code is developed to enable Labs for people who have telemetry or studies disabled.
