as i understood it, firefox3 looks for d-bus messages to decide if it is online or offline. These messages are emitted by network-manager, so if nm is unable to recognize an active connection to the Internet, it will send messages that the computer is not connected, and firefox3 will open offline.
Firefox2 doesn't have this problem because firefox2 is much less integrated with linux(and d-bus,in this case).
