Codetch - Web page editing and more within FireFox

If you haven't seen this before, it's very cool. Found this from one of my fellow TechPodCasts network members, Victor of the Typical PC User podcast.

What does this do? Allows you to edit HTML, XML, XUL and more.

And provides both a code and preview "view" as well right from within Firefox.

Very cool
