FireBug burns away JavaScript errors

I learned recently about another Firefox extension that’s useful for web developers. It’s called FireBug and was developed by Joe Hewitt. Here’s the blurb:

FireBug 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.

It’s a pretty useful little widget that sits harmlessly in the lower corner of the browser indicating potential errors on the page. If you click it, it expands to a full-blown editing window with capabilities to drill-down into the JavaScript and other parts of a web page to see where errors exist.

I’ve been finding it a handy plug-in, and if you develop for the web, you might too. You can download it from Joe Hewitt’s page here or from the Mozilla Firefox Add-ons page here. Version 0.4.1 was released last month, which added Firefox 2.0 compatibility, for all you start-of-the-art folks out there.

If you’re interested in FireBug, you might also be interested in my review of Web Developer, an awesome toolbar of web development tools for Firefox.
