All of my themes and add-ons suddenly became non-supported (in a matter of milliseconds), how do I fix this?

I was just casually browsing the internet, looking at a well-known website, when suddenly, something happened to my theme (felt like it crashed, I do not know the exact vocabulary), then I got a message. I cannot remember what the message actually said, but there was a button which redirected me to my Add-ons Manager. I clicked on it, and I could not see any of my add-ons. Then, I clicked on the prompt that said "Missing something? Some extensions are no longer supported by Firefox. Show legacy extensions." So, I clicked on the "Show legacy extensions" button, and I saw all of my themes and most of my add-ons jumbled up in an "unsupported" category. Can anyone help?

Oh, and this was happening while I was surfing the internet, not after I updated Firefox.

Thanks, Deniz

UPDATE: Firefox 66.0.4 and 60.6.2esr are now available with the new certificate needed to solve this problem. See: Update Firefox to the latest release.

Hi Tedd, there is a general problem with most add-ons at the moment. A critical certificate Firefox uses to verify their digital signatures has expired, and you need a new one to resume using the extensions.

Please see this article for more information: Add-ons disabled or fail to install on Firefox.

Also, Firefox 66.0.4 is expected later today with a fix if the interim hotfix hasn't come through.

Here are the screenshots as a comment, because for some reason, they did not send with my question.

Same here, all but three of my add-ons are now disabled, including AdBlock Plus!

The Add-ons team is working on a fix for this. It looks like a certificate used to sign many popular extensions expired. The verification process checks that certificate, and anything that doesn't pass is blocked.

I don't know how soon re-signed versions of those extensions will become available, or whether another workaround will be discovered. We are all hoping to learn more soon.

Happened to me too. This includes my Norton add-ons. I will be reluctantly be forced to go to MS Edge to keep my Norton add-ons. Someone messed up big-time.
