Add-ons Hidden in Update to Firefox 12.0 beta
After looking through the forums, this seems to be identical to the issue relating to a Firefox 7 update. However, all the tools to bring back the add-ons have been taken down as the problem was fixed in 7.0.1.
Is there a way to solve this problem in Firefox 12? All my add-ons appear to be functioning correctly (NoScript, TMP, etc.) and I can even access the prefs for those that put a link to them in the Tools menu or I have placed on the address bar via a button. But they do not appear in the about:add-ons window which reports that "You have any add-ons of this type installed."

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to do a compatibility check or see if there is a compatibility update available.

Deleting the database files fixed everything after approving the reinstall of all the extensions. Thanks!
You're welcome
Recently updated to 12 (release), and the same thing is happening. Only two of my add-ons appear in the "Extensions" tab on the Add-on manager. I tried to delete the files listed above, but no change. I can see from my folder that the add-ons are in there somewhere!
