The question is, does Mozilla rigorously review every single update of every featured extension? Or did they just vet it once, and a malicious developer may now introduce data collection or similar "features" though a minor update of the extension and keep enjoying the "recommended" badge by Mozilla?

This may also be the reason for the extension begin "Featured" on the Chrome Web Store: Google vetted it once, and didn't think about it for each update.

Yes.

This is just spreading FUD where an answer could have been provided.

> Before an extension receives Recommended status, it undergoes rigorous technical review by staff security experts.

That link doesn't answer the question though. It states that the extension is reviewed before receiving the recommended status. It does not state that updates are reviewed.
