After a Firefox 4.0 restart, all my customizations (done by right-clicking on the menu and selecting Customize...) are lost! I can spend time customizing the toolbar, add-on bar, etc. but all will be lost again the next time I restart Firefox.

I closed Firefox, deleted the localstore.rdf file from the Profiles folder, restarted Firefox, still same problem.

One of the add-ons causes the problem. Looks like the "list.it" add-on is the culprit.
