Help debugging AJAX and JavaScript

As you all know, there is really no easy way to debug AJAX and JavaScript applications, but I found this indispensiblee tool that I just can’t live without. It’s the IE Developer Toolbar. It is still in beta but so far it has been stable. What an awesome tool!!! It let’s you examine the DOM and help you figure out what’s wrong with a certain control, div, etc… The best part is that it works with AJAX requests, so if you make an AJAX request, it actually display the DOM tree after the request so, you will be able to see the changes made to the document. You can also make changes and see their impact on the fly. For example, if you add bold style, you will see the changes right away. You can get it from here or if the link changes then search for it http://www.google.com/search?q=ie+developer+toolbar. Here is a screen shot:
