When you get down to only one tab open, you can't close that tab. If you want to close that tab you have to close the whole Firefox Window.

Set the browser.tabs.closeWindowWithLastTab pref to false on the about:config page to prevent closing the last tab from closing that window and make a close button appear if only one tab is open.
