Debugging Web(3) - Poor man's debugger

This post is for the real poor Web developers who even could not install add-ons on Firefox, at least, there are two spartan debuggers available:

DOM Inspector

DOM Inspector in action
DOM Inspector in action

A neat tool to demonstrate the DOM structure of the Web page. It is far less attractive than the Web Developer Toolbar’s Display Element Information. However, you might find it useful to inspect the add-on’s XUL.

Error Console

Error Console supports to evaluate the JavaScript snippet directly. However, the targeted window’s document is not exposed in the global scope, that cripple the usability of this tool and push me to embrace FireBug. Please leave a comment if I am wrong.
