This is quite rare, but sometimes when simply loading new tab firefox staets to loops endlessly. It start to hang immediately when loading a link to new tab, but I think the new tab appears to tab strip (not sure about this), after that firefox window stops painting and firefox is completely unresponsive.

This doesn't happen with any specific website and I don't think firefox even starts to load the website before it hangs. But I once got this hang while browsing bugzilla.mozilla.org :)

I don't have any extensions and I only have installed flash plug-in plus I have some plug-in stuff from Windows Media Player (npdsplay.dll)

I also catched stacktrace from Firefox with Process Explorer, but I'm not expert with this stuff so I don't know if these are any help.

Here's a stack from the thread that was looping:
ntoskrnl.exe!KiDispatchInterrupt+0x7b
ntoskrnl.exe!KiInterruptDispatch+0x31
xul.dll!XRE_GetFileFromPath+0x1ec

Another stack from the same thread (only second and third line differ):

USP10.dll!ScriptApplyDigitSubstitution+0xa97
xul.dll!gfxWindowsPlatform::UpdateFontList+0x2e40
xul.dll!gfxTextRun::AddGlyphRun+0x29e

If these doesn't help, please tell me what I should do the next time it starts to hang.

Reproducible: Sometimes

Steps to Reproduce:
1. Load a link in some website to new tab (I use midle click or ctrl + click).



Some prefs I have set that might take effect:
browser.tabs.loadBookmarksInBackground = true
browser.tabs.loadDivertedInBackground = true
toolkit.scrollbox.smoothScroll = false (this one changes the tabstrip behaviour)
places.frecency.updateIdleTime = 0 (Not sure about this one, but it's quite unusual)

My bug appears to be a duplicate of this bug, bug 489000, but I'm not absolutely sure. I am running 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10' on a Windows XP Home x86 Dell Vostro 1000 laptop. My situation seems to be that but frequently and most times I right click 'Open Link in New Tab', the new tab web page load seems to cause Firefox start to
loops endlessly in that tab. Also, when this happens, the 'Stop loading this page' does not work. Copying the URL for the page, opening a new tab with 'Open a new tab' or 'File>>New Tab' and pasting the URL causes the page to load properly in that new tab. The endlessly looping tab does not need to be closed for the new tab with the pasted URL to load completely.

I haven't seen this happen in the last year.
