The latest Firefox 4 Beta comes with improved performance, stability and also implemented a “Do Not Track” privacy feature. Firefox now lets you tell sites you don’t want your online behaviour tracked for advertising purposes.
When the “Do Not Track” option is selected in the “Advanced” screen of Firefox’s Options, a header will be sent signalling to websites that you wish to opt-out of online behavioural tracking.
“Tracking is the accumulation and use of a profile by advertising networks through invisible or subtle noting of which sites an individual visits, and the use of the profile data to customize advertisements displayed” – Sid Stamm, Security & Privacy Guy at Mozilla.
Note: You won’t notice any difference in your browsing until sites and advertisers agree to respond to your preference.
