You will have to terminate Firefox from the "Processes" tab of the Windows Task Manager not the "Applications" tab. Then select firefox.exc and use the right-click context menu to "End Process" or use the "End Process" button on the selected process.

Windows 7 keyboard shortcut "Ctrl+Shift+Esc" will go directly to the Windows Task Manager and reopen the last tab that you had open.
