Hi!
I’ve got another firefox addon for you, this one is called “Firebug” and it’s a web debugging tool. I use it primarily for viewing HTML objects, all i have to is to start up firebug and “point and click” the object that i’m interested in and there i go, pure HTML for my eyes, that I can edit in real-time. You can also use this tool for CSS and Javascript debugging/editing.
