Absolutely useless ! Does not work at all, at least on my PC (running under Windows Vista SP2).
It didn't install any sidebar to the "compose " window, nor any scroll-down emoticon menu. Installing that add-on didn't change anything to my Thunderbird display.
Once again, at least for me it is 100% useless.
You'll have to select Emoji from the "View" menu to show the sidebar.
