Problem on testing examples

First, I'm not sure what you're installing. The only thing I'm talking about here is the Firebug extension for Firefox, not any other software. When you open Firebug you have something called the console, it's where all of the error messages and things get printed. That Javascript code I posted will write whatever you want to the Firebug console. If you want to see what a certain object or variable is, use the console.log function inside Javascript code to write the object to the console. It's for debugging.
