Open up the above document and do view-source ( renders blank!!! - Seperate bug ). On quitting the view-source window you should see the following crash: nsBrowserInstance::ReinitializeContentVariables() line 475 + 39 bytes nsBrowserInstance::GetContentAreaDocShell(nsIDocShell * * 0x0012f118) line 497 nsBrowserInstance::Close(nsBrowserInstance * const 0x03cffeb0) line 1496 + 32 bytes nsBrowserInstance::~nsBrowserInstance() line 460 nsBrowserInstance::`scalar deleting destructor'() + 15 bytes nsBrowserInstance::Release(nsBrowserInstance * const 0x03cffeb0) line 563 + 158 bytes nsXPCWrappedNative::~nsXPCWrappedNative() line 398 + 27 bytes nsXPCWrappedNative::`scalar deleting destructor'(unsigned int 1) + 15 bytes nsXPCWrappedNative::Release(nsXPCWrappedNative * const 0x03cfb310) line 71 + 31 bytes nsXPCWrappedNative::JSObjectFinalized(JSContext * 0x03bcc6f0, JSObject * 0x00f78af0) line 96 WrappedNative_Finalize(JSContext * 0x03bcc6f0, JSObject * 0x00f78af0) line 783 js_FinalizeObject(JSContext * 0x03bcc6f0, JSObject * 0x00f78af0) line 1600 + 114 bytes gc_finalize_phase(JSContext * 0x03bcc6f0, unsigned int 113) line 907 + 11 bytes js_GC(JSContext * 0x03bcc6f0, unsigned int 0) line 1173 + 13 bytes js_ForceGC(JSContext * 0x03bcc6f0) line 871 + 11 bytes js_DestroyContext(JSContext * 0x03bcc6f0, int 2) line 219 + 9 bytes JS_DestroyContext(JSContext * 0x03bcc6f0) line 832 + 11 bytes nsJSContext::~nsJSContext() line 366 + 13 bytes nsJSContext::`scalar deleting destructor'(unsigned int 1) + 15 bytes nsJSContext::Release(nsJSContext * const 0x03bcce70) line 374 + 154 bytes nsCOMPtr<nsIScriptContext>::assign_assuming_AddRef(nsIScriptContext * 0x00000000) line 472 nsCOMPtr<nsIScriptContext>::assign_with_AddRef(nsISupports * 0x00000000) line 849 nsCOMPtr<nsIScriptContext>::operator=(nsIScriptContext * 0x00000000) line 584 nsDocShell::Destroy(nsDocShell * const 0x03bcb694) line 1614 nsWebShell::Destroy(nsWebShell * const 0x03bcb694) line 1394 nsXULWindow::Destroy(nsXULWindow * const 0x03bcbbf4) line 324 nsWebShellWindow::Destroy(nsWebShellWindow * const 0x03bcbbf4) line 1779 nsWebShellWindow::Close(nsWebShellWindow * const 0x03bcbc50) line 368 nsWebShellWindow::HandleEvent(nsGUIEvent * 0x0012f63c) line 447 nsWindow::DispatchEvent(nsWindow * const 0x03bcba04, nsGUIEvent * 0x0012f63c, nsEventStatus & nsEventStatus_eIgnore) line 681 + 10 bytes nsWindow::DispatchWindowEvent(nsGUIEvent * 0x0012f63c) line 702 nsWindow::DispatchStandardEvent(unsigned int 101) line 722 + 15 bytes nsWindow::ProcessMessage(unsigned int 16, unsigned int 0, long 0, long * 0x0012f974) line 2795 nsWindow::WindowProc(HWND__ * 0x002a072e, unsigned int 16, unsigned int 0, long 0) line 950 + 27 bytes USER32! 77e719d0() USER32! 77e71982()

Duplicate stack and same actions. By the way, harish, was this in debug or opt build, and "how quickly" did you need to close the window (comments to bug 53871). *** This bug has been marked as a duplicate of 53871 ***

Duh ...

I got the trace from the debug build. I close the, view source, window may be after 10 secs.

Verified dupe.
