I have set my Firefox Privacy to clear history when I close my browsing session. I have also set it to only keep cookies until Firefox closes. When I click on the cookies button mid-browsing, I can see quite a few cookies, which is fine. However, when I close the session and restart, I expect Firefox to have automatically cleared all my cookies. I click on Tools, Privacy and Cookies and all cookies EXCEPT cookies from google have gone. (I do not have google saved as an 'Allow' in my exceptions.) Why are the google cookies not being deleted? Surely I shouldn't have to clear everything manually at the end of each session?
