Microsoft announces changes to Internet Explorer 9’s security features that will better enable users to keep sites from tracking their activity across browsing sessions. The feature is set to arrive in the first release candidate of IE9 early next year. It uses a list to tell the browser which third-party page elements sites can and cannot be blocked from tracking. Microsoft says tracking protection will not be on by default when it arrives next year, and users will need to opt-in to enable it. Microsoft’s IE9 beta has been downloaded 15 million times since its release back in September.
