The cookie permissions haven't been changed. All Firefox versions have allow, allow for session and block a cookie choices when you set an exception.

To see all History and Cookie settings, choose:

• Tools > Options > Privacy > Firefox will: "Use custom settings for history"

Only the 'ask me' cookie setting has been removed.

You can inspect and manage permissions for the domain in the currently selected tab via these steps.

• click the "Site Identity Button" (globe/padlock/control center) at the left end of the location/address bar
• click the arrow to expand the security message
• click "More Information" to open "Tools > Page Info"
• click "Permissions" to inspect and modify permissions
• click "Security" to inspect and modify cookies and passwords in a standalone window

I don't think that option is coming back. What was your usual selection? You could make that your default, and then use an add-on to make individual site adjustments as needed. So the two steps are:

(1) Select a default cookie policy among these options:

• Allow sites to set persistent cookies if they want ("Keep until: they expire") (default setting)
• 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)

Select that on the Privacy panel of the Options page.

(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.

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.

There are other methods for managing cookies and tracking, so if this doesn't suit your needs, I'm sure you can get other suggestions.
