Chrome usually shuts down when its last tab is closed. This extension creates a new window with the same properties as the closing one when this happens. You might get a flicker, but the perceived effect will be that a new tab replaces the closed one.
As there is neither a way to capture the window properties while the tab is closing nor an event that informs about updates to the properties, they are cached whenever the focus of the window or a tab changes (which includes creating new windows and tabs).
This extension only works if the Continue running background apps when Chromium is closed setting (under Advanced) is enabled (it is by default).
XFCE: The properties of non-maximized windows given by Chrome are incorrect as they do not account for border and title bar. This results in a displacement when the window is re-created.
This extension does not collect or send data of any kind to third parties.
