I always had "Private Browsing" enabled, saving no history at all, but since the new Update to Firefox 5, it doesn't work properly anymore. It saves cookies, when I close Firefox, the cookies are still there (like for example for gmail or any other site). Is it a bug? (Setting "Never Remember history") Of course, when manually removing the cookies, they are gone, but appear again once you visit the site again and aren't deleted automatically anymore, when you close Firefox again (which was the case in previous versions)
