if you use the following link

firefox seems to die with a lot of assertions like:

###!!! ASSERTION: No first node!: 'mFirst', file d:/Mozilla/mozilla/content/base
/src/nsContentIterator.cpp, line 960
###!!! ASSERTION: No first node!: 'mFirst', file d:/Mozilla/mozilla/content/base

++DOMWINDOW == 26
###!!! ASSERTION: nsHTMLDocument::Reset() - Wyciwyg Channel  still exists!: '!mW
yciwygChannel', file d:/Mozilla/mozilla/content/html/document/src/nsHTMLDocument
.cpp, line 436

it becomes unavailable

Table-based layout.  Gotta love it.  Especially when the submit button has no text, and a rather unusual (for a website) style rule for the submit "button":  

.CommonTextButton
{
	display: inline-table;
	display: -moz-inline-box;
	display: inline-block;
	margin: 1px;
	padding: 4px;
	border-style: solid;
	border-width: 1px;
	border-color: #999999;
	border-top-color: #cccccc;
	border-left-color: #cccccc;
	background-color: #eeeeee;
	color: #333333;
	font-family: Tahoma, Arial, Helvetica;
	font-size: 80%;
	font-weight: bold;
	white-space: nowrap;
}

Somehow the second one took precedence, which is a violation of CSS rules, I believe.  (Either the first or the third should have happened, but not the second.)  So this guy's using Mozilla-specific hacks, and SeaMonkey trunk does funny things with it.

I also get this assertion:
###!!! ASSERTION: Adding child where we already have a child?  This will likely misbehave: 'Error', file c:/mozilla.org/xpathgen/mozilla/docshell/shistory/src/nsSHEntry.cpp, line 536

I very frequently get this assertion:
###!!! ASSERTION: nsHTMLDocument::Reset() - Wyciwyg Channel  still exists!: '!mWyciwygChannel', file c:/mozilla.org/xpathgen/mozilla/content/html/document/src/nsHTMLDocument.cpp, line 436

Every time I do, we're just adding another DOMWindow:

++DOMWINDOW == 32

Then we get a bunch of these:

and just goes on and on and on...

I am NOT hitting the nsContentIterator assertions.

Henrik, is there any way you can reduce the testcase for this?  The table-based layout is bad enough...

This did hang debug build Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060710 SeaMonkey/1.5a in comment 1.

This did NOT hang Firefox 1.5.0.4 installed build Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4

Probable regression, but I don't know if it's debug-only (which may mean it's not a regression).

[Alex Vincent [:WeirdAl]]

According to Venkman, FTB-FreeTextBox.js line 105 is:
this.designEditor.document.open();

Line 99 is:
this.designEditor.document.designMode = 'On';

[Olli Pettay [:smaug][[e-mail]]]

The hang is the load event problem (bug 335251).
It is hard to make things to work as they should
if all the sites expect something else :(

nsContentIterator assertion is something else.

Comment 5

[Olli Pettay [:smaug][[e-mail]]]

Bug 335251 is now fixed. I don't see nsContentIterator assertions anymore either, 
so marking WFM. Please reopen if there is still some problem with that site.
