Firefox Add-Ons No Longer Work After Update?

If for one reason or another your Firefox extensions have disappeared or won’t work upon Firefox upgrade, then it’s possible that they were disabled during the installation process.

However, the hope is not lost yet as Mozilla’s “Add-on Compatibility Reporter” extension will most likely fix your problem.

After installation, incompatible extensions will be re-enabled so you could test them. As simple as that.

    Either this or “about:config – extensions.checkCompatibility.9.0 – false”. It brings a bunch of extensions back to life.

    But but.. every FF fanboy says to me that new FF versions don’t break extensions so extensions usage is user-friendly and not problematic for average users…

      i use only firefox, im not a fanboy and i can tell you that sometimes, when you update an extension might stop working, until the extension is updated.. or whatever happens

      Although I represent Mozilla on campus, I can tell you those fanboys have false facts. Extensions will break in some way when updating them or Firefox.

    While I don’t use Firefox, this is so popular and known method. No need to share it.
