Is it possible to set an exception list of cookies that won't be deleted, and clear every other cookie?

I have set firefox to clear all cookies when firefox is closed, and that's the way I want to keep it. However, there are a handful of sites where I don't want the cookie to be deleted. I also want the cookies for these sites to be updated when I visit the sites, so I can't simply copy them to another folder. Is there a way for me to set up an exception list to the 'clear all cookies on closing' rule? Thanks Chris

  1. In the Accept cookies section, set Keep Until: I close Firefox. This will make all cookies expire when Firefox is closed.
  2. Add any domains you wish to keep to the Exceptions... list, choosing to 'Allow'. (example: 'mozilla.com')
  • If you are using the Clear history when Firefox closes feature, make sure 'Cookies' is not ticked in Settings..., as this setting will override your Exceptions list and delete all cookies on exit.
