137566 - Mozilla prints out HTML tags instead of using them as tags

Status: RESOLVED DUPLICATE of bug 117441

(Core :: DOM: HTML Parser, defect)

Description

[Sami Mäkinen]

sometimes UBB discussion forum software produces HTML that gets screwed up by
Mozilla. Tags are printed out as-is instead of interpreting them. This happens
rarely, I have no idea what causes it, but I managed to save two pages that
demonstrate this problem. I can get more examples if necessary, but the page has
to be just right in order to get the bug, so it might take a while.

http://fess.homelinux.net/ubb/ultimatebb.cgi.html has a "broken" A HREF tag near
the bottom of the page. The source code is a-ok as far as I can see, and this
page is directly off my HD so there can't be any transmission errors.

http://fess.homelinux.net/ubb/ultimatebb2.cgi.html has a "broken" FONT tag a
little past halfway on the page. Again, the source checks out just fine.

I think this bug has been around for a long while. It's not exactly serious, but
a bug nevertheless.

BTW if you don't see the bug right away, try reloading the page once. I just
managed to load one of the pages without getting the bug, but reloading
recreated the bug.

one more: http://fess.homelinux.net/ubb/ultimatebb.cgi.html has somehow corrupt
tables, even though the HTML should work.

Maybe there's just too many tags?

Pages look fine to me under build 2002041204 / W2k.

Just downloaded build 2002041510, and I'm still seeing the bugs on all three
pages. This is on Debian Linux 3.0.

I recall seeing this in W2K also, but I might be mistaken... but I'm about to
reboot into Windows so I can check there too.

I am on build 2002031104 on W2K, and I'm seeing the bugs on all three pages. Two
of the pages needed to be reloaded once before getting the bug. Furthermore, in
both W2K and Linux, I'm using the Tabbed interface.

Hope you guys don't mind the spam :)

confirmed build 2002041408 win98 but the broken tag isn't always the same. It
changes every time you reload the page, and sometimes may not happen at all.

Attachment: Composite diff of same web page requested twice.

Confirmed under 0.9.9 and build 2002041503.

Refresh is not always required to cause the error. 

Enclosed is a file that shows the differences between requesting the _same_
page twice from the server.

All lines are indented.  The left hand column flags show the lines which are
different (they are not HTML tags)

Some tags are missing.	Others are lt; gt; style tags instead of being
appropriate brackets.

The browser appears to be rendering as best it can what is 'bad' html.
