All of my extensions no longer work. They worked earlier today, then suddenly, they no longer work. I will leave firefox if they are no longer usable here.

My Trend Micro extensions that I rely on are no longer accessible for some reason. My password manager is unusable and I rely on that a lot. I will stop using firefox for good if this problem isn't fixed.

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.)

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.

(I'm sure Trend Micro is just as unhappy as you are about this!)
