Javascript debugging: stopping/breaking at every javascript invocation

Question

I am dealing with a complex legacy javascript code base, and it's difficult to figure out where to put breakpoint (I have to find the files, put a breakpoint in firebug etc).

Is there a way so that Firebug breaks on the first javascript execution that it encounters every time?

In other words, every time I click on something on the page, and if a javascript code is executed, I want Firebug to break on that line?

Of course I don't want Firebug to stop when it executes it's internal javascript.

Is this possible?

Yes, The latest build has a [pause] button for it.
