Access violation if second instance of firefox is opened with specified url

I already have an instance of firefox running and start a new instance from command line using for example the command "firefox.exe www.google.com". After that the second instance is started and the website is shown, but after a few seconds the Windows 7 Application Crash Dialog is shown. Closing the dialog surprisingly doesn't close the application window, which is usable without further problems.

Information from the Application Crash Dialog: 

 Problemereignisname:	BEX
 Anwendungsname:	firefox.exe
 Anwendungsversion:	7.0.1.4288
 Anwendungszeitstempel:	4e83b93a
 Fehlermodulname:	xul.dll_unloaded
 Fehlermodulversion:	0.0.0.0
 Fehlermodulzeitstempel:	4e83b840

 Ausnahmedaten:	00000008
 Betriebsystemversion:	6.1.7601.2.1.0.256.48

 Zusatzinformation 4:	0a9e372d3b4ad19135b953a78882e789

If I start the second instance from windbg.exe (this crashes only if an url is specified) gives: 

(103c.2ddc): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

Firefox will only run one instance at a time. All new windows and/or tabs run in the same instance. To run more than one Firefox executable simultaneously, you need an 2nd Firefox Profile and need to use the correct command line parameter.

As far as that access violation crash report, see a Windows support forum for help with that or search the Microsoft support database for answers.
