I want to be able to close Firefox and have all cookies and site data removed - but I want to keep my history. Checking the box to do just this in 'Privacy & Security' will delete cookies when I close Firefox - but all the site data remains. Under 'History' I have 'use custom settings' enabled, as well as 'remember browsing and download history'. I've tried various permutations of this, but can't get it to do what Firefox says it will. Being able to do this is one of the main reason I want to use Firefox, but it doesn't seem to work. I have to manually delete both cookies and site data. Any suggestions to try to delete cookies and site data when Firefox closes, but remember history?
