If you have a div (child) embedded in another div (parent), and try to set the
childs innerHTML using document.getElementById("parent").firstChild.innerHTML,
changes are not visible in the browser. However, if you access the child
directly by name [document.getElementById("child").innerHTML], all is well. Best
illustrated with the following html code:

<html>
<head>
<title>innerhtml check</title>

<script type="text/javascript" language="javascript">

function writeToChildOf(obj) 
{
	var oListHandle = document.getElementById(obj).firstChild;
	oListHandle.innerHTML = "Child Div innerHtml Changed. No bug.";
}

</script>

</head>

<body>

<a href="javascript://" onclick="writeToChildOf('aParent')">Test</a> 	

<div id="aParent">
	<div id="aChild"> Click on Test to change this message. No change => bug. </div>
</div>

</body>
</html>


Reproducible: Always
Steps to Reproduce:
Load above html code into browser. Click on Test.

Actual Results:  
Test
Click on Test to change this message. No change => bug.


Expected Results:  
Test 
Child Div innerHtml Changed. No bug.

The problem exists not just with embedded DIVs, but also SPANS embedded  in a
DIV. ie, <div><span>blah</span></div>.

Works as expected under IE 6. Since innerHTML was copied over from IE, I guess
compliance with IE behaviour is more or less what people would come to expect.
innerHTML is working fine.  firstChild for the outer div, however, is a Text
node corresponding to the line break you have in the source, not an Element
node.  Text nodes don't have a way to set their innderHTML
