One of Firefox 3's newest (and most revealing) backend features is its built-in usage tracking—it keeps a running tally of how often you visit a web page over a period of time, which informs the Smart Location Bar's suggestions and creates things like smart bookmark lists of "Most Visited" sites. Smarter features informed by your behaviour are great, but checking out the raw data can offer a whole lot of insight into where and how you spend your time online. Exactly what site have you visited the most since you installed Firefox 3 and how many times did you go there? Here's how to find out.
