Google, Microsoft, Apple, and Firefox’s Mozilla, have at last formally agreed to include a “Do Not Track” button (DNT button) in every browser. {Let’s take this opportunity to explain that the way this works is that using the “Do Not Track” option inserts a special “Do Not Track” header into your browser. In fact, as we shall see, there may not even be a DNT button involved – you may need to be a super-user type to even find the “Do Not Track” option.} Their capitulation comes just before the Obama administration’s appeal to Congress to pass a “privacy bill of rights”, but don’t expect it to mean that they won’t still be mining your data. (P.S. See below for how to enable Do Not Track in Safari.)
