Cookie exceptions not saving

I am using Firefox stable version 24 on Windows 8.1 (RTM).

I would like to clear all cookies upon exit of Firefox, except for those sites specified in the exceptions list. When I add websites to the exceptions list they are saved until I restart firefox, at which point the exceptions list becomes empty again.

I have tried to play around with the about:permissions page, but the list of websites on the left is also empty despite me having visited numerous websites in the current browsing session.

Any help would be appreciated.

In case you are using "Clear history when Firefox closes":

  • do not clear the Cookies
  • do not clear the Site Preferences

Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, and passwords.

Clearing cookies will remove all specified (selected) cookies including cookies with an allow exception that you want to keep.


Let all cookies expire when you close Firefox.

  • Firefox/Tools > Options > Privacy > Cookies: Keep until: I close Firefox

Create a cookie 'allow' exception for cookies that you want to keep.
