The wikitionary thing is working great for me but im still wondering how to use the "wikipedia" thing.
This review is for a previous version of the add-on (2.0.7).Please check WikiLook Option dialog. Or simply press Ctrl and do RightMouseButton click.(Shift for new Wiktionary pop up, Alt for Uncyclopedia).
