InformationWeek posted a news story that Internet Explorer 9 adds support for the consumer-friendly HTTP header concept developed by Firefox.

In an unexpected shift, Microsoft has said that Internet Explorer 9 will support Do Not Track. The consumer privacy feature, developed by Mozilla, transmits a header to any Web site that a user visits, indicating whether the user agrees to have their movements tracked online.

But Dean Hachamovitch, corporate vice president for Internet Explorer, said that Do Not Track alone will not sufficiently protect consumers. Accordingly, Microsoft will still include its own feature, Tracking Protection Lists, to forcibly block tracking by unapproved sites
