As reported here, uBlock added a user tracking feature. Well, after news spread on Reddit, uBlock on Firefox has been reverted to the almost three year old version by the Firefox team, as can be seen here and on Mozilla.org (note version on left sidebar is now Version 0.9.5.0.1-let-fixed Last updated 3 years ago (Oct 31, 2015)).

They remove add-ons when they think they are unsafe. Sometimes in sneaky ways, just mentioning a GUID. https://bugzilla.mozilla.org/show_bug.cgi?id=1461625 [mozilla.org]
Go figure why uBlock got fixed in addons.mozilla.org and not blocked, because they have such tool, and it works even if you disable auto-updates. https://blocked.cdn.mozilla.net/0f0764d5-a290-428b-a5b2-3767e1d72c71.html [mozilla.net] (now you know which add-on the bug report was talking about, this page links to the report, but the report doesn't link back or mentions the name)
