HTTPS-Everywhere 2.2.1, Firefox 14.0.1. Any changes made using the preferences panel work for current session only and are not saved. Steps to re-create: (1) Open preferences, navigate to entry for (say) Flickr. (2) Disable the entry, green check mark becomes red x. (3) Close browser. (4) Re-open browser, open preferences, navigate to previously disabled entry. Now re-enabled. Is this a bug or a feature?
