Visualize every Javascript event bound to elements on a webpage

This is a handy little tool that I found the other day... it let's you see a visualization of every Javascript event on a page.

The only problem is that apparently it doesn't take into consideration dynamically created events. But still, it does a good job of giving you a "big picture" of all the events on a page.

Find it here for Chrome. Not sure if there's a firefox version too.
