In the morning we mentioned that some Firefox users began to notice that the installed browser extensions were suddenly disabled.
Extensions appear in the tab of add-ons messages of the type “could not be verified for use in Firefox and has been disabled” (could not be verified for use in Firefox and have been disabled).
Accordingly, Firefox displays the message “One or more installed add-ons cannot be verified and have been disabled” (One or more installed plugins cannot be verified and have therefore been disabled).
As mentioned the problem due to the expiration of its certificates Mozilla. You can tell by turning back his watch computer you, and you will see that everything works just fine.
But because this is not a solution, and because it can cause other problems, we have better news.
The Mozilla Foundation has announced a temporary fix. According to company, the hotfix will address the signing issue of add-ons.
We rolled out a hotfix that re-enables affected add-ons. The fix will be automatically applied to the background within the next few hours.
Let's say you do not have to do something for yourself. You just have to wait until the Mozilla Foundation has implemented the hotfix and the information reaches your computer.
