Editor’s Notes: Almost every website use some kind of tracking code, leaving all websites for the sake of privacy would mean visiting no website at all. If you see tracking services such as Google Analytics, Quantcast, etc on a website, you don’t need to fret. Such services are used by webmasters to check how many people are visiting their websites. This add-on is for advanced users who hate being tracked by few services for the sake of their privacy. In other words, if you are a normal internet user then you shouldn’t worry.
Ghostery is a free add-on for Firefox that lets you know which websites are tracking you. Since more and more websites are using the tracking codes and scripts to monitor their visitor’s behavior, you can keep check on these websites by using this add-on.
According to the developer,
Ghostery alerts you when you visit a web site that has web bugs on it. Web bugs are hidden scripts that track your behavior and are used by the sites you visit to understand their own audience.
Once installed, it will load up in the status bar and alert you whenever it finds tracking codes(web bugs) on any website that you visit.
This add-on supports over 135 services and keeps updating them weekly. I am currently using Google Analytics(to track the number of visitors) and few other Google services on my blog.
Note: Some scripts are also used for advertisement, custom search, etc, so they are not a big threat to one’s privacy.
If you don’t want a specific serve to track you, then you can simply leave that website. Enjoy!
