I have upgraded to Firefox 7 and now when I start Firefox with my shortcut on Vista it starts. But when I want to start another copy (instance) of Firefox, nothing happens. With Firefox 5 it was working? The strange thing is that if I do that, first copy of Firefox is nuable to close. It is not visible when I close it, but it remains in processes so I can't start Firefox again. I must kill it in Task manager first.
