Correct order is ORDER LAST USED Rated 5 out of 5 stars
Oh dear Lord NO PEOPLE! Tab order SHOULD ABSOLUTELY NOT be as they appear in the tab bar! This extension looks to replicate alt tab behavior. Get a clue about what "alt tab" behavior is and you'll see why it's in order the tabs were last used.
Good grief people... get a clue before you comment. Great extension btw. Does what it says.
