I use NoScript to enforce HTTPS protocol to encrypt the data in Facebook, I added "*.facebook.com" in the NoScript HTTPS configuration and I can use Facebook with HTTPS but I can't enter to the "Privacy configuration" if I have NoScript on (Desactivating NoScript everything works fine)
Firefox show this warning (I translated from spanish to english):
