So this little app isn't just for mac uses, but for everyone using firefox. I figured alot of people here, myself included, prefer firefox over Safari, and I've found a sick add-on for it. It's called stumble. It's a little button on your toolbar that you click and it takes you to a random site, based of your preferences. You give Stumble feedback by clicking thumbs up or thumbs down, and the system gets to know your personal preferences.
