Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox profile folder to reset the extensions registry. New files will be created when required.

See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions

If you see disabled, not compatible, extensions on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button (in Firefox 4: right-click the extension -> "Find Updates") to do a compatibility check.
