very nice addon. but if addon's menu item exists top of the menu items, this add-on is perfect!

almost perfect. it adds a context menu and works. It would be nice if you could only add "new tab besides" without sub menu. (duplicate tab could be another extension or you could have the option to use it or not).

Thanks for this! In my opinion, it would be even better to make just one button in the context menu, "New Tab". For "Duplicate Tab", there are already other addons. And my personal preference would be to make it the first item in the context menu, like in Chrome. That way it would be much faster to use.

Although, the shortcut is very handy (thanks!) so maybe I'll just learn to use that.
