How to debug Javascript on old browsers
<p>Forgive me if this has been asked elsewhere.  I was not able to find a good answer yet.  I have some Javascript code that works perfect in the latest release of Firefox.  However, there is some odd behavior on an older browser that is used on our site.  For reasons beyond my control, I need to support this hacked up version of a browser that is actually embedded into another piece of software.</p>

<p>I am stabbing in the dark as to the cause of the issues.  I see no error console and of course tools like Firebug are a pipe dream.  How do I effectively debug browser-specific issues?  The old guess-and-check method will cost way too much time.</p>
