Why do I get this error when executing this javascript?

Question

== Issue
==
I have another kind of problem with Firefox
== Description
==
<code>var firefoxWindow = getWindows()[0];
var browser = firefoxWindow.getBrowser();
var doc = browser.contentDocument;
var elem = null;
var elems = doc.getElementsByTagName('td');
for(a=0;a &lt; elems.length;a++){ if( [[elems[a] !== null && elems[a].hasAttributes() <u> true && elems[a].getAttribute('onclick') !== null && elems[a].getAttribute('onclick').toString().match(/doNothing/gim) !== null && elems[a].getAttribute('onclick').toString().match(/Goodbye Wonderful/gim).length &gt;= 0) || (elems[a] !== null && elems[a].onclick !== null && elems[a].onclick.toString().match(/Goodbye Wonderful/gim) !== null && elems[a].onclick.toString().match(/Goodbye Wonderful/gim).length &gt;= 0]]) { elem = elems[a]; } }
var found = false;
var window = null;
for(var i=0; i &lt; firefoxWindow.frames.length; i++) }
function recursiveSearch(frames){ for(var i=0; i= 0) || (elems[a] !== null && elems[a].onclick !== null && elems[a].onclick.toString().match(/Goodbye Wonderful/gim) !== null && elems[a].onclick.toString().match(/Goodbye Wonderful/gim).length &gt;= 0))) { elem = elems[a]; } } if(elem) else{ if(frames[i].frames.length&gt;0) }}}if(!elem && window.frames.length &gt; 0){ recursiveSearch(window.frames); }var origColor = '';if(elem !== null) elem.style.backgroundColor = 'yellow';}
</code>
Using this javascript through jssh to assert that there is a element with an onclick handler that contains the phrase Goodbye Wonderful returns an odd error message :
Received: uncaught exception: [Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: interactive :: :: line 1" data: no]
I've looked just about everywhere for an answer and none of them have anything to do with what I'm trying to do with this javascript. It works fine in FF 3.6 but when run in the 4.0b1 this causes that weird exception.
== This happened

Every time Firefox opened
== Updated to FF 4.0b1

Sorry but the javascript syntax got messed up a little bit when posted. And jssh was built with 4.0b1 and then I packaged it as an XPI to install as an extension.
