Close Unused Blank Tabs 作者： Dustin Luck

Each time you open a new tab, this extension will close any blank tab you opened and forgot about (except the active one). Don't let those unused blank tabs sit around doing nothing.

I built this extension because I start my browser with a blank tab and launching a bookmark set to open in a new tab would always leave that initial blank tab to clean up. You may find it useful in other cases too!
