When I look at the options used from Internet Explorer for the cookies, I read the following description:
Blocca i cookie di terze party privi di una versione compatta dell'informativa sulla privacy.
Its translation is roughtly:
Blocks the cookies without a compact version of the privacy's informative.
I don't get which cookies are blocked. From that description, it seems the cookies should include a compact description of the privacy informative, but I don't get how cookies can contain that information, or what happens with cookies set from sites outside the European Union.
What cookies are blocked?
The screenshot has been taken from Internet Explorer 9, but that words were used also from previous versions. The settings are the ones shown for the "Privacy" tab; I don't recall if the English version calls that tab the same way.
This is the screenshot for the English version.
