FireBug 0.4

The next generation of JavaScript debugging is upon us, and it’s name is FireBug. For the uninitiated, FireBug is an addon for Firefox that makes developing JavaScript easier. Besides a new JavaScript debugger with breakpoint support, it allows you to write debugging info to a console window, evaluate JavaScript in a command line (not unlike Eureka for IE), monitor the contents of XHR calls, inspect the DOM structure of a page, and determine the actual styles being applied to elements. This little gem will save you a lot of development time when used regularly. I highly recommend it.
