Ghostery is a Firefox add-on that tells you who’s tracking you while you’re visiting a website. It’s no surprise that real estate “media” sites like TruZill use visitor tracking software — makes sense since they’re selling ads.
According to Ghostery:
Ghostery alerts you about the web bugs, ad networks and widgets on every page on the web.
Web bugs are hidden scripts that track your behavior and are used by the sites you visit to understand their own audience.
Download Ghostery and a little red ghost will appear when you land in a spooky place. Click the icon and see who’s got eyes for you. Click the tracker to learn more about it. A neat little Ghostbuster.
