1089044 - Firefox ignores HTML tags after a while if there are many without close tags.

Status: RESOLVED DUPLICATE of bug 256180

(Core :: DOM: HTML Parser, defect)

Description

[Cory H]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141011015303

Steps to reproduce:

Created pages with many HTML tags without end tags.
This page works, scroll to the bottom of the page to the hyperlinks:
http://individual.utoronto.ca/doortocor/

After adding more "headers", the following pages don't work (scroll to the bottom of the page to reach the hyperlink, and compare with the page source):
http://individual.utoronto.ca/doortocor/page.htm
http://individual.utoronto.ca/doortocor/page1.htm
http://individual.utoronto.ca/doortocor/page2.htm


Actual results:

After almost 200 HTML tags that don't have end tags, HTML tags begin to be ignored.


Expected results:

HTML tags should continue to work.  On Internet Explorer, Safari, and Chrome, these pages load without issues.

Only after adding end tags, the page loads properly in Firefox with more "headers":
