Firefox Time Tracker

blog

I always thought I could reduce the amount of time slacking if I could track my time on facebook, reddit, hackernews… like I track my calories intake to reduce my weight. I couldn’t find a good firefox plugin for that so I decided to make one.

I’m opensourcing the code right here: https://github.com/mimoo/FirefoxTimeTracker

I’m pretty surprised with Firefox SDK and it’s actually easier than what I thought to build a browser plugin. It might also help that everything Mozilla documents is clear and pretty.

At the moment the code successfully logs the time passed on different websites across sessions. It just lacks nice graphs. If you want to try it just wait a couple days until I ship.
