/** Test for Bug 490040 **/ // Ensure we can store the window if needed. // Close the window as soon as the first tab loads, or // immediately if there are no tabs. // Use executeSoon to ensure this happens after SS observer. // Only windows with open tabs are restorable. Windows where a lone tab is // detached may have _closedTabs, but is left with just an empty tab.
