After updating to v. 24.0 (and restarting) ALL add-ons (regardless whether they work or not) are marked "(disabled)", and clicking Enable button does nothing


After updating to v. 24.0 (and restarting, several times) ALL add-ons (regardless whether they work or not) are marked "(disabled)". I tried clicking "Enable" button for each add-on and nothing happened. There is only one add-on which is marked as incompatible with this version (but it was also incompatible with previous version, and so marked). Clicking "Update Add-ons", gives a short list of add-ons but "Install Updates" button is pale and doesn't work. I can only sort list by name or last update. Also, I disabled Ask Toolbar and that went well. When I click "Enable" button (button works ONLY for this add-on) it takes forever to get note: “Ask Toolbar will be enabled after you restart Firefox”, I used to get this info in seconds time before this update. (I do not really want Ask Toolbar, I just used it to see whether if I disable and then enable an add-on might do the trick.) Bottom line – I can not tell if add-on works (i.e. if it is enabled or disabled) unless I try using it. Even when I posted this question and installed Troubleshooter, it's also marked as "(disabled)"

Thanks a lot! I didn’t get a chance to try last cor-el’s suggestion (first I was away, than to busy). Couple days ago I turned browser on and found my problem had magically disappeared!

It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the extensions.* files (e.g. extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

If you see disabled or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end side of the Search Bar to check if there is a compatibility update available.

If this hasn't helped then also delete the addons.sqlite file.

You can use this button to go to the Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

You're welcome

Are this screenshots from an extension window because the built-in about:addons page looks different?
