I use my laptop with an external keyboard, mouse and monitor when I am at home. In order to look up a word when in Firefox I have to select it and then lean forward and do a 3-finger tap on the trackpad. It would be more convenient if I could select "look up" on a page from the right-click context menu brought up using the mouse (as Chrome allows).
Is there anyway I can add this feature to Firefox? I've tried a few FF plug-ins but I haven't found one which works the way I want.
