Rated 4 out of 5 stars

great tool, I use it all the time.
But a very annoying behavior for me, when you close the new opened tab, it doesn't return back to the from tab, but to the first tab on the left. That's the only problem for me for this fantastic tool. Thanks and congrats :)

This review is for a previous version of the add-on (0.3.5.2). 

But you can change this behavior with other extensions:
LastTab (https://addons.mozilla.org/firefox/addon/112/)
or
Tabberwocky (https://addons.mozilla.org/firefox/addon/14439/)
