CookieMan Context is a Firefox addon, adds a context menu to Firefox's cookie manager and permissions dialogs. It will enable you to manage permissions for cookies.
Once it is installed, start Firefox and click on Tools menu > Options. Click the Privacy panel, then click the Show Cookies button. (You may have to choose "Use custom settings for history" in the first drop-down for the Show Cookies button to appear.)
When you right click on a web site name in the cookies list a context menu will appear, allowing you to set its permission status without having to open the cookie Exceptions list.
The context menu choices are:
1. Allow - allows the site to store cookies
2. Session - allows the site to store cookies until you exit Firefox, at which time they will expire
3. Block - removes the sites cookies and it will not be allowed to store future cookies
4. Copy web site address - copies the selected web sites address to the clipboard
5. Delete - removes the cookie(s) stored by the selected site
