Since updating to 3.6.11 I can't open multiple browser windows. Windows 7 Pro

Using Win 7 Pro I've always been able to open multiple Firefox browser windows. Since updating to Firefox 3.6.11 I can only open one window at a time. I can still have multiple windows open using Internet Explorer or Chrome.

Don't select anything right now, just use "Continue in SafeMode."
