How to disable third party cookies in Firefox
How to disable third party cookies in Firefox.

The first would be to disable it manually by opening about:config from the address bar. Search for network.cookie.cookieBehavior and take a look a the value. If it is set to 0 you accept all cookies, 1 means you only accept cookies from the same server, 2 means you disable all cookies. Setting it to 1 has the same effect that the option in the old firefox browsers had: it disables third party cookies.
