That's true, Firefox 44+ no longer have that option. I don't think this feature will be coming back, but if you want to suggest that, you can use the following site (click the sad face): https://input.mozilla.org/feedback/firefox Firefox should still be using the block/allow list you have accumulated so far. To control cookies from sites you haven't visited before, I suggest: (1) 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) * Block sites from setting cookies (Uncheck the box for allowing sites to set cookies) (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.
