Firebug is a must know tool for web developers now. If you've heard of it but haven't had time to play around with it please look at these videos to see what you're missing out on. The first tutorial covers an introduction to debugging ajax applications with firebug. The second tutorial shows you how you can manipulate CSS live on your webpage without having to change code, reload, change code, reload. I hope people will find this useful. I would also suggest you head over to http://www.getfirebug.com
and make a donation to Joe for all his hard work on this amazing extension.
I have the videos in two formats. One is a link to youTube, and the other is a better quality downloadable Quicktime file.
