Debugging with Firebug
Joe Hewitt of Parakey in the latest Dr. Dobb’s Journal provides a detailed overview of Firebug extension for Firefox: “Firebug breaks the page down into a set of tabs that depict its most important aspects—HTML, CSS, JavaScript, the DOM, network activity, and a console for errors and log messages. No tab is an island; Firebug lets you browse code just as you browse the Web by presenting objects as hyperlinks that can take you from one view to another.”
