Hi RRL1030, that is no longer a built-in of Firefox after version 43. To more closely manage cookies in today's Firefox, here's what I suggest: (1) On the Options page, Privacy panel, select a default cookie policy among these options: * Allow sites to set persistent cookies if they want ("Keep until: they expire") * Allow sites to set only session cookies ("Keep until: I close Firefox") '''(I use and recommend this second option)''' * Block sites from setting cookies (Uncheck the box for allowing sites to set cookies) ''Note: to reveal specific privacy settings, choose "Firefox will: Use custom settings for history'' (2) Install an extension that makes it easy to make site-specific changes, such as Cookie Monster. The Cookie Monster button on the toolbar allows you to see permissions for first party and third party cookies and to change them. https://addons.mozilla.org/firefox/addon/cookie-monster/ Sample screen shot attached -- the option to "Apply cookie settings to both HTTP and HTTPS" is turned on, which streamlines the menu. With this option you don't have to set/modify permissions for both HTTP or HTTPS on the same site. Alternately, some users prefer the Self-Destructing Cookies extension, which quietly sweeps away cookies when you close all tabs to a site. I haven't tried that one myself. https://addons.mozilla.org/firefox/addon/self-destructing-cookies/
