When I close firefox it doesn't close. I go to reopen it and it says that it is already running. I have to use task manager to end process to close it before i can log back on.

After browsing and I close Firefox it appears to close. However when I go to reopen it later I get a message that Firefox is already open and I need to close it. The only wany I can close it is by using Task Manger to end process.
