Ghostery shows you the invisible web : cookies, tags, web bugs, pixels, beacons and companies interested in your activity. Then it helps you learn about those companies, so you can make informed decisions about what you are/aren’t willing to share, and control your online privacy.

After you’ve seen what’s tracking you, you can decide whether or not you want to block any or all of the companies in Ghostery’s library. Are there some marketers you trust, but others you’d rather turn away?
