Updated: List of AJAX Automated Testing and Debugging Tools

While there are a lot of testing tools out there to look for bugs, test a Website's scalability and perform unit tests, precious few seem to handle automating the testing of AJAX applications.  As a result, I wanted to start a list of tools that support automated testing of AJAX applications as well as debugging.  If you have other tools or applications you know of or something listed is out of date please add a comment to the blog and I'll get the information added/updated.
