Track the Amount of Time You Spend Online in Firefox

Everybody makes New Year's resolutions, and I wonder how many of you made the resolution to waste less time browsing the internet? If so, here's an easy way to track the amount of time you spend online.

The TimeTracker extension for Firefox gives you a really easy way to track the time you spend directly in front of your browser. The timer only ticks if you are browsing, and you can exclude work-related sites from the timer as well.
