Bug Description

Binary package hint: firefox

When visiting http://www.chutneymary.com/critics.htm simply remaining on the website for about 30 seconds sends cpu usage through the roof and eventually locks up firefox. The application becomes unresponsive slowly at first and the completely locks up.

Reproducible: every time

I can confirm this behavior. We still need to do further analysis of this issue.

firefox 3 issue is most likely a dupe of bug 215728

Bartek (tschew) wrote :

most definately not a duplicate, i don't have the issues described in 215728, this bug only manifests itself after about 30 seconds (or more as it seems, depending on the machine) on that chutneymary page

By the way, dragging the red box on http://www.raizlabs.com/blog/?p=210 does not cause the issue for me (cpu usage goes up while dragging, but no crashing or anything is observed).

Agreed that this definately isn't a duplicate, so I've removed the link. I can reproduce it here without fail, and during the high CPU usage there is virtually no disk I/O and the urlclassifier3.sqlite file is not being modified at all. These are different problems.

I've seen similar issue by visiting http://www.pragprog.com/ in Firefox 3, except I'm seeing 100% on X, which locks up the entire gnome environment for 20 seconds at a go. How firefox is locking up X, I have no idea. Visiting the same site in Konqueror doesn't lock up X.

Sean; If you're seeing Xorg go to 100%, then it's likely you have a different issue (video card drivers perhaps?)

Sean, I can't reproduce what you're seeing on my system.

Maybe one of your extensions?

we have a few performance issues open. the ones that spring to my mind are:

1. "perfomance issues for scrolling pages with fixed position elements"

2. "performance issues for scrolling pages with tiled backgrounds"

this sounds more like a flash bug.

Alexander, this is not a "performance issue", cpu usage jumps to 100% suddenly after about 30 seconds, there is something fundamentally wrong in how this page is being rendered.

Bartek, i have dual-core cpu, and firefox crash faster then yours 30 seconds.
Use only 50% cpu power (one core) and memory usage go up and up, to hung the system (before this i obviously kill firefox app).

Bartek (tschew) wrote :

Same here pioruns (dual core) but it does take about 30 secs for firefox to "lock up". It's actually possible to close the tab that the page is in to alleviate the problem, so it's not a complete lockup.

"I dont see any issue."
Alex: Oh man, were we talking about the pragprog bug that sean reported? I think that should definately not be in this thread. Seeing as you confirmed the chutneymary bug a couple of months ago ("took longer than 30 seconds to reproduce") I think we were talking about separate issues here. I was referring to chutneymary. I don't see the pragprog issue either.

website bug. they misuse the window.onerror= handler to setup new
timers ... which then accumulate over time and you end up having lots
and lots of timers firing causing CPU bustage.

And what you say about memory usage going to roof and destabilize system?
You try to say, that's is OK?

I think Firefox should read and try to display *any* website. When they are broken, stop trying to display, but NOT hungs itself and whole operating system!

Firefox has a big problem as you say. This problem's cause is mozilla
community. If they fix that with their updates, you will realize that,too.
Even if it goes on, you can use Opera or Google chrome.
