We all procrastinate sometimes, either reading the online newspaper, browsing blogs or playing addictive Flash games. A bit of distraction that bad but if it gets out of control it may end up affecting our productivity. This is where this Firefox extension may come in handy.
Meetimer keeps track of the time you spend on each webpage while you're browsing the Internet. As it also enables you to categorize webpages in different groups, at the end of the day you get a pretty accurate idea of how much time you spend on each kind of website. You can create new groups, although they may need a browser restart to be displayed. These statistics may help you to achieve a better time organization and become more proactive.
The extension is free but the author suggests making a donation to charity organizations.
