I cannot repro this bug, but I have definitely seen what you show in the screen
shot before, on other sites. Over to Harish since he is generally interested in
that stuff...

reproduced with latest build on separate machine
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:0.9.4+) Gecko/20010924

same site, different tag being displayed and not parsed

<TD valign="top" bgcolor="#333333">

screenshot 1:
screenshot 2:

these were not on the same refresh. the first was taken, I browsed a bit more, 
and after a few other links, returned to
bin/ultimatebb.cgi?ubb=forum&f=3 and saw the second screenshot 

refreshing fixes it. I cannot find a condition that reproduces this. It seems 
to happen randomly on my Windows 2000 machine AND on our development XP

created new profile per instructions, went to
and clicked "Just some BS"

screenshot here:

still have the same symptoms. this time a </td> is displayed in the first 

please note that despite the error on a cell close tag, the columns are not 
disturbed, as a missing </td> often does. They are still in alignment. I won't 
speculate why this is so.

taken from Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:0.9.4+) 

later tonight or tomorrow I will try a more recent build.

lastly, should i continue with the screenshots?
dschin: The screenshots are fine, and I think they help describe the problem.
However, that last one ( seems
to be corrupted, as it's not loading for me.

When you try a more recent build, be sure to delete your old Mozilla directory
before installing the new build.

Anyhow, I still can't reproduce this, but I'll mark it as NEW.

See bug 102218 which was marked as a duplicate.  You should be able to
reproduce it easily at that site.

I'm not able to reproduce the problem. When I tried the URL mentioned in bug
102218 it asks me for userid & passwd. Could someone please attach a testcase?
It is not a good idea to open up a bug based on a dynamic page. At least attach
a copy of the problem page and may be we can derive a reduced testcase out of it.

just experienced bug with 0.9.5 on

all screenshots are now at

the most recent example is mozillabug6.png and (mozillabug6.html is the 
associated HTML file, as requested by

again, its not consistant, and I cannot reproduce it at will. however, i do 
post a lot on that messageboard, and will get it randomly at least once per 
session. try browsing topics, and hitting "back" to go back to the index 
screen a few times.

also, realize that when i am browsing, i'm a registered user and logged in. 
(session vars and cookies are both probably utilized.

I just registered a test user, "mozillatest" to use. email me for the pw if 
you do not want to register yourself.

I'm the person who filed bug 102218.  In it I wrote you that can email me and I'll
send you the user id and password.  I also wrote that because of the prolem with
view source and pages generated by posts, I can't see if Mozilla is rendering
the source incorrectly, or if the source is being mangled before it gets to
the renderer.
Irregardless, email me at and I will send you the user id
and password.

Looking at the Palm Beach County web site again with 0.9.5, I can see it exhibits
the same behavior that is seeing.  The anchor tag followed by the
anchor text is displayed, and the closing anchor tag is not displayed.  It only
seems to happen in tables.
I used IE to save the source, and used 0.9.5 to view the file.  I could not get
it to fail.  So you must view the site directly.  Please email me at so Mozilla will work properly with this site.

same problem with nightly build. this time, a < script > tag is displayed

HTML capture for screenshot attachment id 57067

choosing View-Source was yielding a blank window, so this was generated by
saving the web page via file->save as.

again, using build Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:0.9.5+)

I'm having the same problem with some server side includes that are not parsed,
but displayed!

In every other browser i don't se the tags rendered, but in mozilla i get, for
example, "<%INCLUDE /folha/>" outputed as text in the html
final rendering.

I'm using a nightly build downloaded today (ID: 2003020808)

This is still showing up in Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US;

comment #25 refers to bug 72565 and is irrelevant to this bug.

Comment 28

I am experiencing the same problem for files on my site that have certain
truetype fonts, running Build 2004042110 (1.7rc1) on Fedora Core 1 (2188). The
problem does not occur with 1.6 on Windows 98, but does occur with 1.6 on Linux.

The fonts are SPIonic, SPTiberian, and SPEdessa. The problem can be observed in
the following files, all in the directory

q02.htm    q03.htm    q04.htm    q05.htm    q06.htm    q07.htm    q08.htm    
q09.htm    q13.htm    q18.htm    q19.htm    q20.htm    q23.htm    q25.htm    
q26.htm    q29.htm    q30.htm    q31.htm    q32.htm    q33.htm    q35.htm
q39.htm    q40.htm    q41.htm    q42.htm    q43.htm    

It should be noted that the fonts have been detected by Mozilla and appear in
the list of fonts one can select in Edit | Preferences | Appearance | Fonts.

It should also be noted that the same problem appears when using the Gnome
browser, as in the Navigator file manager, but it does not appear when using the
KDE browser, as in Konqueror, which displays all fonts correctly. It might be
useful to examine the source code for each of those browsers to see why one
works and the other doesn't.

I should add that I considered the possibility the value of the face attribute
in <font face="SPIonic"> ... </font> might be case-sensitive, and experimented
with different cases in both the HTML page in in the files themselves. That
didn't help.

It seems that the HTML5 parser does not have this problem.
