After updating Firefox to 5.0.1 the add-ons Manager did not show any of my add-ons, although they were all running. Several restarts of Firefox, even with the add-ons disabled did not bring them back. I then installed another add-on and after restarting, all of the previous add-ons are now shown in the manager.

Running on Mac 10.5.8. Add-ons installed: Adblock Plus, Add-on Compatibility reporter, Ant Video Downloader, Forecastfox, Google toolbar, Reload Every, Session Manager, and Steep and Cheap Watcher.

Note: the troubleshooting information was taken after the problem was fixed. Prior to fixing the issue, there were no items under the Extensions heading. Add-on Compatibility Reporter was the add-on that was added to restore all of the other add-ons, even though it was already installed.

Good to know you solved your own problem by simply installing another extension, I like solutions that aren't going to cause extra work, or loss of data.

Here is what people normally have to do for missing extensions, as if not installed.--

FWIW, renaming or deleting extensions.sqlite and the other files beginning with "extensions." causes the files to be rebuilt from the extensions directory, so nothing is lost, but they will be restored in alphabetical order.

I've solved places.sqlite problems by simply restoring a bookmarks backup, or creating a bookmarks backup and restoring that rather than face loss of history.

Please mark as solved so others will see your answer when looking for solved problems as solutions to there own or other people's problems.
