This setting will allow basic cookies, but block third-party cookies. Essential cookies means that the cookies downloaded to your computer come from the web page you are currently viewing. Third-party cookies are cookies set 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 stored on your computer, it will be a third party cookie.
You can also accept third-party cookies, but this is generally not recommended unless necessary for a specific website to work. To also enable third-party cookies, go to Tools, Internet Options and again click on the Privacy tab.
This time, click the “Advanced” button and you can check the box next to “Turn off automatic handling of cookies” and select “Accept” for third-party cookies.
