Privacy advocates have beeen asking the browsers to provide users the ability to block tracking their information by advertisers. Websites use many third-party advertising partners, and some may use shady surveillance schemes, perhaps without the knowledge of the websites.
Internet Explorer 9 will let users add lists of sites that they don’t want tracking them. Users will have to create or find their own lists of sites they want to block. The feature won’t be automatically turned on when it debuts with the release of Internet Explorer 9 early next year.
It has been demanded Microsoft to work directly with privacy groups to identify and create lists of sites that engage in controversial forms of tracking, instead of giving the total responsibility to the user. But Microsoft takes the stand that, it doesn’t want to judge which sites are OK to track consumers.
