in History/Recently closed Tabs, menu not close after after move mouse.This review is for a previous version of the add-on (18.104.22.168-signed).
I am only able to reproduce this in the case where there is only one 'recently closed tab' in that list. In that case the submenu containing that item disappears when you middle-click the item, but the other menu levels don't auto-close. A simple workaround in this case, is to run the mouse pointer over one of the still-open menus and then back off the menu (mouseover, mouseout). Alternatively you can just click outside the menu. I'll add this to my bug list, but it really shouldn't be a frequent issue. If anyone is seeing this issue more often than just that very limited case, please contact me (via http://www.shadetreeapiary.com/extension/Forms/contactform.htm or http://forums.mozillazine.org/viewtopic.php?f=48&t=633732 ) with specific steps to reproduce. Thanks.
