StumbleUpon FF Add-on

This has to be my favorite FF add-on ever! Makes finding new, awesome websites a breeze!

1. Download and install in FF
2. Use the StumbleUpon start page to select your interests (don't be afraid to be broad!)
3. Your done! When ever you feel like stumbling, click the "Stumble" button and you'll stumble upon a site in your interests!
4. Tell StumbleUpon whether you like it or not (using the up and down hands), and add it to your faves! (if you like it)

StumbleUpon "learns" about what sites you like based on which sites you tell it you like and which you don't.
