In the example URL provided, attempting to load the page produces a hang within
the browser. External windows can still be accessed. After a wait of between
15-20 seconds, the browser becomes "unhung." However, attempts to use the
browser or to access the affected page result in severe instability and crashes.
All newly-rendered text is written in bizarre fonts; for instance, on this
computer "Star Jedi" and "Chris Pirillo" fonts frequently appear. Right-click
menus develop black borders and white bars in place of many menu items; rolling
over menu items may make some options visible (this is a handy method for
closing the affected page and restoring a modicum of stability to the browser).
Images display only as blackened silhouettes. As a final insult, unless quick
action is taken (right-clicking to close), Mozilla crashes, reporting an error
in XPICOM.dll, if I remember correctly.

This behavior is not just restricted to Slashdot; I have seen it on other sites
and regret not writing down their URLs. As I come across more examples in the
wild of crash-triggering sites I will post them here. I will install 1.4a
immediately to test if this behavior repeats; however, I will not that I have
seen it since well before 1.2.1. Apologies if this is a duplicate; I spent half
an hour searching Bugzilla and could not find a bug that accurately described my

Reproducible: Always

Steps to Reproduce:
1. Go to http://slashdot.org
2. (to be absolutely specific) Right click on any link with over 400 comments,
to be conservative
3. Wait approximately 2-3 seconds for hang.

Actual Results:  
1. Loaded
2. Right click menu works appropriately
3. Hangs and produces desktop-wide graphics irregularities- images load as black
silhouettes, backgrounds become white in color, fonts are overridden to
least-used types, crashes result.

Expected Results:  
1. Load
2. Right click menu works
3. Display page properly, after appropriate loading time.

Configuration: Windows ME, Duron 800 Mhz on VIA chipset, nVidia Geforce 3

Crash in: xpcom.xpi or xpcom.dll (will confirm crash location)

Do you happen to be a moderator on Slashdot when you see this problem?
Since you're win9x, how are your system resources when you see the problems?

System resources go through the roof. The bug happens whether I have mod points
or no- although it does seem marginally slower.

By the way, I'm still seeing the behavior in 1.4a now that I've upgraded. Also,
I have more information to add, in the form of a popup alert Mozilla sends to me:

"Error creating picture; you are low on system resources."

You may want to consider upgrading to a more robust OS
Low Resources is the bane of Win9x

Having read the bug this is marked as a duplicate of, I have to say that I don't
really think it's the same issue... but that's okay; maybe when that bug is
resolved this one will too. Especially since I'm 

What bugs me is that Mozilla doesn't do this on pages that are larger; I don't
get the same behavior when, for instance, the testcase for bug #32669 comes up.
In fact, my machine managed to load that one after a period of waiting, and I
managed to scroll through it, albeit slowly. Not once did I suffer graphics
corruption in that window or in other windows.

I won't reopen, though; I'll leave that to your judgement.
