Ghostery for FireFox was designed with internet users who have serious concerns about their privacy being protected. It provides users with information about the companies that are tracking them and tells them more about the privacy policies and opt-out options that those companies offer their visitors. It informs you about web bugs, pixels, beacons, and detecting trackers that are used by companies like Google and Facebook to track information about the customers who visit their sites. You can use Ghostery to block scripts based on the company that is using them and dispense with local shared objects.
Ghostery itself uses only pings to provide you with the installation software and upgrade, yet even those pings are non-identified. It does not use cookies, and the information that it collects is compiled anonymously. You can choose to opt-in or opt-out of Ghostrank, which provides information to the Ghostery programmers about the types of tracking software that you stumble upon in your browsing. The programmers use this to improve the list of items that are detectable by their software, effectively helping all of its users to protect themselves against ever more complex threats that can access information that they do not want to be shared with anyone.
