Deletes cookies whenever you quit the browser works as expected

OK

Doesn't seem to work anymore. Doesn't delete cookies not in the whitelist. They just remain even after restarting firefox, despite manually doing with clean button. Can confirm by visiting Privacy Settings > Manage Data.

This used to be a great extension, but it no longer works. Cookies from sites that are not on my whitelist are not being deleted. They remain after I restart Firefox and even after manually clicking the “clean” button.
