I have a function, say f(args), that is being called from many places in my code.

When args is undefined f() throws an exception.

I would like to identify who called f() with the undefined parameter.

What would be the easiest way to find the exact line (file name + line number) that called f() ?

Is that possible to see the caller in Firebug ?
