Firebug: a JavaScript, CSS, HTML and AJAX debugger

May 24th, 2006

If you need a comprehensive JavaScript, CSS, HTML and AJAX debugger then you should have a look at Firebug. Firebug is a Firefox extension that "lets you explore the far corners of the DOM by keyboard or mouse. All of the tools you need to poke, prod, and monitor your JavaScript, CSS, HTML and Ajax are brought together into one seamless experience, including a debugger, error console, command line, and a variety of fun inspectors."

Firebug 0.4 was just released yesterday by the author Joe Hewitt.

I have had my problems debugging AJAX so hopefully Firebug can come to the rescue here.

    Per, have you used the Ajax Toolkit Framework incubator code from Eclipse? It's got a Javascript debugger integrated into Eclipse along with:

    - a DOM Inspector view
    - an XHR monitor
    - a Javascript console
    - Javascript syntax validation (this is a life saver in Ajax apps)

    The only tricky part is that it's still in alpha-status and the pre-req stack is large and fragile; feel free to send me an email ( if you'd like a pre-configured workbench with the most recent ATF code.
