There is a problem with an expired intermediate certificate that is used to sign extensions. This is being worked on by the Add-ons team.

See:

• [/questions/1257928] Will the disabling of add-ons be fixed, or is it the new way?
• https://discourse.mozilla.org/t/certificate-issue-causing-add-ons-to-be-disabled-or-fail-to-install/39047

At about 6:10 PST we received a report that a certificate issue for Firefox is causing add-ons to stop working and add-on installs to fail.
Our team is actively working on a fix. We will update as soon as we have more information.

So despite what Wakkowarner said I assume once that is remedied all removed addons will be restored or will I have to restore them all myself manually afterwards?

Mozilla has rolled-out a fix for this. The fix will be automatically applied in the background within the next few hours, you don’t need to take active steps.

In order to be able to provide this fix on short notice, they are using the Studies system. You can check if you have studies enabled

1. Go to [=] > Options > Privacy & Security.
2. Make sure Allow Firefox to install and run studies is check marked.

I you had it disabled, you can disable studies again after your add-ons have been re-enabled.

They are working on a general fix that doesn't need to rely on this and will keep you updated.

Thanks that worked and updated within a few seconds actually and once I disabled it again the addons at least for the time being are all back again.

Thanks

Note that the hotfix is currently applied via a shield study, so you only get this fix when studies are enabled.

Right but you can disable it afterwards that is what I did I enabled it as directed and then disabled it as soon as I got my icons back and it's working fine with the studies disabled. As Chris stated

(Typo fixed!)
