TrackMeNot is a Chrome add-on that can help you maintain your privacy by protecting you from data profiling by the major search engines. Most search engines will track and use search history to create profiles that serve targeted ads to the user - naturally there is a legitimate concern as to what else this data could be used for. TrackMeNot uses a clever approach that hides your real searches among a large number of bogus search queries that are periodically sent to the major search engines (AOL, Yahoo!, Google, and Bing), significantly increasing the difficulty of aggregating such data into accurate or identifying user profiles.You can review and edit the list of dynamically generated search terms, adjust the frequency of the searches and also disable TrackMeNot at any time.
