Question

I can deny cookies and allow some domains. I can delete cookies when they expire, or when I close Firefox. What I want to do:

• Generally accept cookies
• For all domains on my "exceptions" list (which I'm not using to allow / deny a cookie), keep cookies until they expire
• For all other domains, delete cookies when I close Firefox, or maybe when I "Clear private data"

It seems this can not be done via the standard settings. But can I hack some config, get some plugin, etc.?

Please note that the CookieSafe icon has two menus, that you reach by right-click and left-click. CookieSafe is very complete in its capabilities.
