Works in Fx4 Rated 5 out of 5 stars

Works in my Fx4. Icon is there, in add-ons bar. I like "right-click, then left-click" better than "right-click, then hold Control as you are releasing the mouse". The ability to copy with titles is awesome. Overall, beats the other extension mentioned in the comments, hands down.

This review is for a previous version of the add-on (3.0.0.16).
