Mozilla has released Firefox 4 Beta 11, the newest version of the popular web browser. It not only adds several performance and stability improvements, but it implements a “Do Not Track” list to enhance user privacy.
Earlier this month, Mozilla announced its intention to implement "Do Not Track" in Firefox 4. “When the feature is enabled and users turn it on, web sites will be told by Firefox that a user would like to opt out of OBA,” Mozilla privacy lead Alex Fowler said in a statement". “We believe the header-based approach has the potential to be better for the web in the long run because it is a clearer and more universal opt-out mechanism than cookies or blacklists.”
Mozilla argues that the HTTP header approach sends a more universal opt-out signal to websites.
