In the morning we mentioned that some Firefox users began to notice that the installed browser extensions were suddenly disabled.
The extensions display the "could not be verified for use in Firefox and has been disabled" tab in the add-ons tab (they could not be verified for use in Firefox and have been disabled).
Similarly, Firefox displays at the top the message "One or more installed add-ons cannot be verified and have been disabled" (One or more installed add-ons cannot be verified and are therefore disabled).
As mentioned the problem due to the expiry of Mozilla's certificates. You can find it by turning back your computer clock, and you will see that everything works 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 the company, the hotfix will face the signing problem 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.
