Check that you are saving cookies and data in FF under Privacy and Security in the settings menu

Hello.

It may be possible that you have set Firefox not to remember cookies and hence you are getting logged off each time you close the browser. Go to Tools -> Options -> Privacy and make sure that you unchecked “Always clear my private data when I close Firefox”.

Thanks,
