If you're struggling to get your Firefox extensions working today, you're not alone – a technical glitch has rendered all add-ons unusable, and Mozilla is currently working on a fix.
As Engadget reports, it looks like an out-of-date certificate has borked everyone's extensions, as Firefox is simply recognizing them as incompatible.
Tweets from the official Firefox browser and Mozilla Add-ons accounts show that the issue is being worked on behind the scenes, but as yet there's no estimated time for when everything will be back working normally.

It sounds as though the problem should be cleared up sooner rather than later though – we'll update this article if we hear anything more.
With the vast library of extensions one of the main reasons for choosing Firefox as a browser, no doubt millions of users are feeling inconvenienced today.
From blocking ads and cleaning up page layouts, to quickly sharing pages to social media and streamlining downloads, Firefox add-ons can provide a big boost in functionality on top of the core browser itself.
You can even use Firefox extensions on the Android version of the browser, so they can travel around on your smartphone.
"So sorry for the issue we’re having with add-ons right now," Firefox said in a tweet. "We’re working hard to fix it and will keep you updated."
