1. Go to;txt
Actual Results:  
Firefox 3.5.1 closes window after some time using one processor core to 100%

It's a XFX 750i with a Q9400@2.66GHz, 4GB RAM (1GHz), no overclocking and more than enough room on the 250 GB RAID 
Good enough? :-)

I do NOT try to download the file. The page opens, is busy and then Firefox just closes dwon. I do NOT click on anything

No problem here with the site. Can you try the following trouble-shooting options:

- Firefox's safe-mode to exclude extension/theme problems
- a new profile
- a reinstall in a new empty folder

I made a new profile, installed all my add-ons and it worked fine. But then I found the reason for the problem: I do NOT allow cookies in my default profile. As soon as I allowed it for it worked fine.
So the problem is obviously the function on the cnet website. Still I find the behaviour of Firefox kind of buggy.

Thanks for the help.

> - a reinstall in a new empty folder
I just checked and indeed, I see the hang. But I tried also Opera and Google Chrome and they hang too, although not as serious. Not sure why Firefox has no choice than too hang.

This won't be a cookie bug... my guess is some bad javascript that's creating an infinite loop or somesuch, as a result of not being able to set cookies. Though it must be a bit more complex than that, given it ends with a crash rather than a slow script dialog.

I can reproduce this with cookies disabled. Memory usage slowly went up to about 500 MB and then the window closed. No crash reporter. A reduced testcase would be nice here.

I can confirm this with cookies disabled just for Behavior of FF is not normal, even when the script is bad.

When I set:


to false, it still reproduces. So, it is not TM related.

Problem still there with 3.5.2.

Comment 14

I copied the page to my local disk. I started Apache. I added the <base href="..."> tag, disabled all cookies and loaded the page via

It doesn't reproduce that way. There is no XHR. I see that both with original site and copy. So, what could be the difference? A real domain name????

Anyone any ideas? This is spooky. This way I can't reduce it.

I tried to see where the hang was occurring but couldn't.

Anyways, the debugger was complaining about line 114 of the CookieXfer.html file (contained in the attached) returning no value, just before the hang.

By the way, this bug also results in run-away memory consumption, if the hang is left to run its course.

Sorry for the bug spam.  I should have mentioned that I'm reproducing this on the current trunk builds.

Comment 18

Some notes.

The CookieXfer.htm is loaded by <iframe> if you have cookies disabled. If cookie is enabled, it will not appear on the site (the server probably reacts on the http header info).

The CookieXfer.htm is loaded 4 times in the attachment of #15. Probably, only 1 was intended.

The path of oreao.js in the CookieXfer.htm is not correct (bug in saving). Remove the first part of the path.

But that doesn't help to reproduce it locally. There are still some things that are necessary to reproduce it locally. Don't know what the CookieXfer.htm file is doing. Probably to do an alternative when cookies are disabled, but I don't know what.

Probably some paths have to be corrected, to get reproduced locally. But then I need to know what it is doing.

Maybe a bisect could help (if it doesn't reproduce with older versions). Then we have some clue where to look.

Maybe it gets into a kind of event fire loop.

You crashed because windows ran out of memory. This happens.

This is probably just spam cause there doesn't look to be much information, but not sure.  Might help. Anyhow my crash report:

Sounds like we produced a mangled dump. Not much we can do about that (until we get to a multi-process setup).
Reporter:; Is this still a problem with FF4 ?
