This is normal behavior if firefox isnt closed down properly (example: reboot without closing firefox) or if it crashes this is normal. How are you closing firefox before this happens? if you close it with the X on the top of the page or with <file> close you should not see that error. please try and let me know how you are closing it to get this error.
