How to catch an event in Firebug

Question

JavaScript

Good day.

The situation is something like this. There is a big big project. And there is a certain DOM element, by clicking on which something happens. Is there a way to start debugging immediately after this event fires?

Searching through the code and placing breakpoints in the supposed places where the call can take place, so that later on the stack to find the event handler, does not lead to success. Mainly because of the number of sources.

I looked at the eventbug plugin for firebug - it shows event handlers, but does not allow you to break in the right place. Search by handler code is also not suitable, because this is actually a minified ExtJS, and eventbug only provides the code with omissions. Ideally, I would like to break as soon as this handler starts executing.

Or I misunderstood with eventbug'om?
