Firefox is having an add-on 'meltdown'

Topic

Over the last several hours, reports are being posted from users worldwide that Firefox has disable all or nearly all of their add-ons. I’ve lost all my add-ons except one. What a mess!

The Firefox team indicates it is apparently due to an expired intermediate cert. They are working on a fix.

Win10 Pro x64 21H2, Win10 Home 21H2, Linux Mint + a cat with 'tortitude'.

Quite the mess!  Guessing we will have to reinstall the add-ons after the certificate is fixed.

From @martinbrinkmann on ghacks.net:

Your Firefox extensions are all disabled? That’s a bug!

Solution
Nightly, Dev and Android users may be able to disable signing of extensions; some users reported that this resolved the issue temporarily on their end. You need to set the preference xpinstall.signatures.required to false on about:config to disable signing. You could change the system date to the previous day to resolve it temporarily as well, but that can lead to other issues.

The issue can only be resolved on Mozilla’s end. The organization needs to renew the certificate or create a new one to resolve the issue. I’d expect Mozilla to do that soon as the issue is widespread and affecting lots of Firefox users.

Users should not remove affected extensions from their installations; the issue will resolve itself once Mozilla fixes it.

When you posted this, I wasn’t seeing any problems either. But now… I’ve got a “some extensions could not be verified” warning 🙂

I’m having the same problem.

I’ve shut down this thread, in favor of Susan’s blog post here.
