Mozilla Firefox is a very popular browser. Mozilla Firefox was the result of an open source project and is owned by Mozilla Foundation. It has great features like session storage, which allows a user to recover access to the open tabs after a user has closed the browser window. It has a feature in which a user can open multiple tabs in a single window.
The latest version f this browser is Mozilla Firefox 4, which is considered to be safe and stable for Internet browsing. It is based on the Gecko 2.0 web platform and it is available in 57 languages as well as it has a brand new appearance for Windows Vista and Windows 7 users. It has numerous features. The web is developing rapidly and so are the ways that your data is composed, shared and stored. Now with the introduction of the Do Not Track option in Mozilla Firefox, a user will be able to ensure a Do Not Track box in the advanced screen of Firefox’s options. If a user selects this option a header must be sent signaling to websites that user wishes to select online behavioral tracking. The user will not be able to see any difference while browsing until the advertisers and promotional or other sites starts giving feedback to the header.
Firefox’s new Do Not Track feature works when Firefox user enables Do Not Track (DNT) header within browser. Then after the browsers sends DNT header to a website that responds by providing content. Finally advertisers respond by placing non-personalized ads & logs user’s activity anonymously. Do Not Track privacy feature is meant to stop online advertisers from monitoring user’s online activity. Mozilla’s Do Not Track feature relies on an HTTP header that signals to ad companies that a user doesn’t want to be tracked.
Mozilla suggests an opt-in mechanism for users, which would allow them to select out of tracking feature in the browser. The Do Not Track information will then be sent by Firefox to a content server that also hosts tracking advertising. The ad server then replies with ads that are not personalized and has the tracking information relating to a particular user.
