Find all event listeners on a link, including delegated listeners?

[Matt Kruse]

I'm trying to reverse-engineer a page (Facebook, in particular) and
figure out what happens when a certain link is clicked. For this
exercise, I only care about Firefox.

What is the best way to find out what happens when I click a link,
what function calls are fired, and on what elements they are attached
to as listeners?

I have Firebug, of course, but perhaps I don't know how to use it
correctly to find this info.

Thanks,

Matt Kruse

May not get you everything, but as an idea try this:

Turn on profiling, click a button, then turn profiling back off.

Give one of the dev builds of chromium a shot...

Open the debug console, click scripts tab (in chromium, don't remember
firebug equivalent), hit the pause button (looks like two vertical
lines), click the link.

Try the developer tools in chrome, you'll never look back.
