This setting will allow first-party cookies, but will block third-party cookies. First-party cookies means that the cookies put on to your computer are from the web page you are currently viewing. Third-party cookies are cookies left by a domain other than the one you are currently viewing. For example, if you go to yahoo.com and a cookie from weloveads.com is put on to your computer, that would be a third-party cookie.
