The upcoming version of Google Chrome (v.41) will include a new feature that will allow the user to reduce the amount of information shared by referring sites to third parties
 
Typically, a website can collect from the header of the browser information, which specifies  the referrer’s website, that the user was browsing, as well as other personal details through cookies or similar technologies.  The new feature will remove a portion of the identifying information from the address bar, thereby reducing the amount of information which third parties receive
