Hi,

in standard HTML you would write
<textarea name="description" cols="80" rows="20"></textarea> to produce an empty
textarea.
In XHTML you have to use <textarea name="description" cols="80" rows="20"/> .
Mozilla doesn't handle this right. It will show the sourcecode following the
textarea.

Snippets used to test:

Not working:
<html>
<body>
<form>
<textarea name="description" cols="80" rows="20"/>
<h1>blah</h1>
</form>
</body>
</html>

Working:
<html>
<body>
<form>
<textarea name="description" cols="80" rows="20"></textarea>
<h1>blah</h1>
</form>
</body>
</html>

(The missing XHTML Header doesn't change anything, so I don't paste it here).

Greetings, Klaus

Reproducible: Always
Steps to Reproduce:
1. Just create two html files of the snippets above and open them.

Actual Results:  
Textarea is not empty!

Expected Results:  
The textarea should be empty :)

No, you don't have to use that.  In fact, you cannot use that unless you are
serving the page as an application/xhtml+xml document.

Otherwise, the page is parsed as HTML and so HTML syntax rules apply.  And that
syntax requires a </textarea> closing tag.

I wrote that the missing header doesn't change anything.
You can also try:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="de" lang="de">
<body>
<form>
<textarea name="description" cols="80" rows="20"/>
<h1>blah</h1>
</form>
</body>
</html>


BTW: Every other XHTML tag style command (like <br/> <hr/> etc.) is parsed
correctly. So why should only the textarea be invalid?

Appearently if you put this content in a .html file it doesn't work but in a
.xhtml file it works.

The problem arises with CGIs which output xhtml where you can't change an ending.

So it looks like the doctype is ignored or something like that.

No, it not about the doctype.

It works locally with .xhtml files because FF assumes that a .xhtml file is
application/xhtml+xml.

It will not work on a live server unless the server sends the page that way.

This bug is invalid.  Do not reopen it.
