One of the programmers I worked with has something similar in code:

 var head = document.getElementsByTagName("head")[0];
 var e = document.createElement("script");
 e.type = "text/javascript";
 var b = "function moo() { alert('hello'); }";
 e.appendChild(document.createTextNode(b));
 head.appendChild(e);
 moo();

This is all good and dandy, but I would like to step into moo(), and firebug just can't do that. I know I can rip the whole thing apart, but I reallllly don't want to touch it and his code works :)

Any ideas how I can debug this with Firebug?

Cheers
