Make Firefox the browser you want it to be, with extensions that offer faster, safer, more efficient browsing
All kinds of hidden tracking systems--tags, hidden pixels, beacons, and more--follow you around the Web. Ghostery makes the invisible parts of the Web visible. For example, when I used the service and visited CNN.com, a list of seven different companies invisibly tracking my session popped up on my screen. Ghostery can help you identify and avoid almost all of them by blocking the images and scripts they use to keep tabs on you.
