Occasionally when navigating to/from the offending tab, Firefox will crash outright as described below. CPU and memory loads go to 100%. Another user reported the following behavior: Second time loading of the same page the machine was again sometimes not responding, and i tried to switch to another FF tab (one of about ten) and this worked after a while, but when going back to the slow tab again, and while freezing, Firefox closed with this error: Windows Error box: "Microsoft Visual C++ Runtime library (red cross) Runtime error! Program C:\Program Files\Mozilla Firefox\Firefox.exe This application has requested the runtime to terminate it in an unusual way. Please contact the application's supoport team for more information. OK" Reproducible: Always Steps to Reproduce: 1. Navigate to URL of very large XML file. Actual Results: Extremely unresponsive system, CPU and memory loads go to 100%, browser occasionally crashes. Expected Results: The XML file should be opened without crashing or becoming unresponsive and with minimal CPU/memory loads. Note: Internet Explorer 8.2 demonstrates correct behavior. Fails on: C2D T9300 Windows 7 Ultimate up-to-date, FF 3.5.4, 4GB installed. C2D E6600 Windows XP Pro up-to-date, FF 3.5.4, 4GB installed.
Confirming using Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2b6pre) Gecko/20091231 Namoroka/3.6b6pre, but I don't get the runtime errors. I also crashed once - http://crash-stats.mozilla.com/report/index/bp-2544c346-c432-4f8c-b29b-889762091231 IE also has a difficult time loading this site and it froze too. In fact, my entire system froze and I had to reboot this win 7 x64 machine.

Ever confirmed: true
It would be nice to get the crash stacks that the original reporter got to see if they match what I got.
Marcia: that's bug 536224, it might or might not be the same bug....
We see this in the Red Hat bug report https://bugzilla.redhat.com/show_bug.cgi?id=608691 Closing that bug as a duplicate of this one.
