Ghostery is a browser extension available for all major browsers that allows you to have full control over who can track you, which site can track you, and how they can track you. It was recommended by Edward Snowden during the SXSE conference on how you can keep your online activity as private as possible. Yes, you can always use Google Chrome Incognito mode or private mode from other browsers. But by using those browser mode, you are giving the choice between all or nothing, and still there is no transparency in terms of who’s tracking you.
