Congratulations! You've downloaded or compiled a copy of Gran Paradiso Alpha 1. This means that you've volunteered to become part of the testing community. Helping out won't take much of your time, doesn't require special skills, and will help make the next version of Firefox even better.

Note: The Gran Paradiso Alpha 1 build you are using is NOT A FINAL VERSION of Firefox, it has been made available for testing purposes only, with no end-user support. If that sounds scary, you'd probably be better off with the latest version of Firefox that you can download here.
