PageAddict is a Firefox extension that will help you monitor your Internet addiction. Once you install it, choose PageAddict from the Tools menu to display a summary of the time you’ve wasted on each web site for this day, and a graph of your web surfing habits from the past. You can categorize different sites and restrict how much time you spend in each category in a day.
PageAddict stores all information locally in your Firefox browser and does not send your private information to any external location.
You need Firefox to use pageAddict.
