The privacy of internet users is continuously on stack from various directions with the evolution of technology. Modern technology in the field of internet poses serious threats on the privacy of users. Unfortunately, while surfing on internet, we are careless about our privacy and allow intrusion of privacy to a great extent without objection. This facilitates advertisers in tracking user activities on web by third party cookies. Researchers have been conducting vigorous research on this topic and also have presented solutions to control the leakage of privacy without user consent. But surprisingly, major research activities confined to the desktop platform and little is known about web tracking on mobile devices. We survey current technologies and purpose a novel approach for android based mobile devices which control excessive tracking of users. Further, Mozilla Firefox add-ons and other related proposals dealing with cookies and privacy are analyzed.
