for example using jQuery  $("#content").append("<div /> something </div>");
will append malformed HTML, and FF will render it.

so this renders
<div /> something </div>

it should produce an error, or render it like
<div />
something
</div> <-- extra closing div

Expected Results:  
i am not sure what the best solution is for this, it might be best to leave it as is.  i think the best solution would be an error in firebug or a console write, but Firebug really only detects JS errors.

maybe something like "unbalanced, or extra ??? closing tags/elements exist in this document" in a console log

i chose this as a minor problem over trivial as it relates to standards rather than just the presentation of the object.
Keywords: xhtml
Does this problem persist if you don't use jQuery, such as doing:

  document.getElementById("content").innerHTML = "<div /> something </div>";
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>a page title</title>


</head>

<body>
<div id="content">
	<div id="someTitle"><strong> a title </strong></div>
</div>
<script>
	document.getElementById("content").innerHTML = "<div /> something </div>";
</script>
</body>
</html>
the HTML result is different than the XHTML version

in the html version it seems self healing
in the xhtml version:
<
something

is the result.

i am not sure either is really right.  i think the best scenario is if an error is visible to the designer in firebug or at the console
Creating Testcase.
Attached file Plain html
While developing this testcase, it appeared that Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9) Gecko/2008052906 Firefox/3.0, the version using "document.getElementById..." did not show the text "something" in the HTMl, when rendered. 

However, in testcase2.html, I removed all the script and put <div/>something</div> (which is very invalid code), and something appeared. This is in XHTML 1.0 Transitional. 

As for the <div />, that is invaild in and of itself (being an empty tag, like img). But, Firefox is treating "<div /> something</div>" as it is supposed too. The ending </div> closes <body> and <html>. Here is the validation field for the div with Dreamweaver
"tag: " html" allows optional closing tag. closing tag:  "div" closes "html" context. Validation will proceed as if context is closed.[XHTML 1.0 transitional]". 

So, while the div is wrong, Firefox is rendering it correctly. 

With the scripting example, Firefox is also treating the code with the contempt it deserves. The last </div> is invalid, being treated as a text entity, but the < messes it up. Because "something" is left in the cold, Firefox ignores it.

The error console tells you why.

Else, this a a dupe.
