Your Firefox extensions are all disabled? That's a bug! - gHacks Tech News

Some Firefox users started to notice that installed browser extensions were all disabled in the web browser suddenly. Extensions would display "could not be verified for use in Firefox and has been disabled" messages in the add-ons manager of the browser. Firefox would display "One or more installed add-ons cannot be verified and have been disabled" at the top as a notification next to that.
Affected extensions include LastPass, Ghostery, Download Manager (S3), Dark Mode, Honey, uBlock Origin, Greasemonkey, NoScript, and others.
Update: Mozilla started to roll out a fix for Release, Beta, and Nightly versions of Firefox. The fix uses Mozilla Studies, and you need to make sure that this is enabled to get it. Mozilla notes that you may disable Studies again after the fix is applied and add-ons have been re-enabled. You need to make sure that "Allow Firefox to install and run studies" is checked on about: preferences#privacy. End
Only options provided were to find a replacement and to remove the extension in question; this left affected users puzzled. Was this some kind of preemptive strike against policy violation extensions? Mozilla did announce that it would enforce policies more strictly.
The answer is no. Turns out, the issue is caused by a bug. If you read carefully, you notice that verification is the issue.
A new thread on Bugzilla suggests that this has something to do with extension signing.
