Debugging JavaScript with Firefox

Posted on April 22nd, 2007 by Jason

Here are some miscellaneous tips for debugging HTML, CSS, and JavaScript in Mozilla Firefox.

They include references to Firefox extensions (plug-ins) that you will need or want, as well as tips for configuring Firefox, how to actually invoke the debugging procedures, and a few shortcuts to keep in mind. A number of landmines are also pointed out along the way. (Please avoid stepping on those, because it gets messy.)

Minimally Required Firefox Extensions:

- Does your installation of Firefox have a DOM Inspector option on the Tools menu? If not, reinstall Firefox with the Developer Tools option turned on (Custom | Developer Tools).
- Install the Web Developer Extension (http://chrispederick.com/work/webdeveloper/), if you have not already done so.
- Install the JavaScript Debugger (aka. Venkman, http://www.mozilla.org/projects/venkman/).

Optional Firefox Extensions:

- Install View Source Chart (http://jennifermadden.com/scripts/ViewRenderedSource.html)
- Install the Load Time Analyzer (by Google).
- If you are running on Windows, you might want to install IE Tab (http://ietab.mozdev.org/).
- 200+ other developer extensions are listed at https://addons.mozilla.org/search.php?cat=4.
