Today's Download of the Day over at Lifehacker is a keeper. PageAddict is a an add-on for Firefox (also available as a Greasemonkey script) that watches your browsing behavior and makes a log of how much time you spend at each site. All of the information is stored on your computer, not transmitted anywhere, so your time-wasting secrets are kept between you and your browser (and, well, any snoops you foolishly let use your browser). Once it's collected some information, PageAddict gives you a breakdown, and you can use tags to categories sites as "work," "play," or whatever you like. It seems to me like a good way to guilt yourself into getting more work done, but if you want to go hardcore you can also restrict sites to a certain number of minutes each day.. One caveat: PageAddict is smart enough to know which tab is active and if the browser is currently in focus, but if you, say, leave Cute Overload in the active tab and then go on your lunch break, your logs are going to be skewed.
