Firefox extension to find out which Javascript event is bound to an inspected element?

Visual event 2

Visual Event is an open source Javascript bookmarklet which provides debugging information about events that have been attached to DOM elements.


There's no way to enumerate listeners added with addEventListener in Firefox core (bug 448602).

There may be workarounds, but I'm not aware of any. See also How to find event listeners on a DOM node when debugging or from the JavaScript code?

[edit] Oh wait, determine "which events are bound"? Did you mean which events can fire on the node? If so, you should clarify your question.
