Google says IE privacy policy is impractical in modern Web

Microsoft's privacy protection feature in Internet Explorer, known as P3P, is impractical to comply with while providing modern web functionality such as cookie-based features, Google said in response to an accusation from Microsoft that Google had bypassed privacy protections in Internet Explorer.

Newer cookie-based features are broken by the Microsoft implementation in IE, Google said. These include features such as Facebook "Like" buttons, the ability to sign-in to websites using a Google account, and hundreds more modern web services. It is well known that it is impractical to comply with Microsoft's request while providing this web functionality, Google added. Google said it has been open about its approach on P3P, and so have other websites including Facebook.
