some Mozilla product is still open (or is running in the background) close any that you see (including Firefox,thunderbird, seamonkey,older emusic download manager etc) then

open task manager

go to the 2nd tab (processes) and look for remaining processes and kill them

usually a addon or sync service stops proper closing of Mozilla products.
