This has got to be one of the greatest Firefox Extensions aimed at the Web 2.0 developer. I know I have enthused over a lot of add-ons for developers but I promise that this might be the very best one I’ve seen yet–really!
FireBug is a docking pane that essentially replaces the Firefox DOM Inspector, JavaScript Console and HTTPRequest Sniffer all in one fell swoop. The pane docks against the document loaded into the current tab or window and shows information only for that page. The best part is that the DOM inspector included with this tool is far simpler and more powerful than the one installed with Firefox. Go get this one now!
