Works in Fx4 Rated 5 out of 5 stars
The icon is there in addon bar. Selecting action only with mouse buttons is more intuitive than having to use Control key as in other addon mentioned in comments. Support page is excellent, very helpful, thank you. Overall, this one really stands out and beats other similar addons hands down.
Proved this to myself many times: Don't go by reviews, go by number of weekly downloads. Nutcases are always there. Normal people mostly just download and enjoy.
