Review for Duplicate Tab by Alan Meyer
Rated 5 out of 5 stars
This is a surprisingly useful add-on. I often find that I want to go back to a previous page, but not lose the page I'm on. With Duplicate Tab I duplicate the tab (which duplicates all the history too), and then press the back button in either the original or duplicate window.
If you've never done this you might wonder if it's useful. It is. Once you use it a few times you find yourself using it over and over.
