You can 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.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
