Blocking Facebook social plug-ins is a good idea. But this add-on, at this moment of review, does not work at Firefox v.16.
There are other ways. Use Google for "Facebook social plugins disable".
Word definition itself is great. Yet, it needs customizable key-toggle for pop-ups. Current Shift+Right Mouse Button also opens Firefox context menu, which hides the word definition pop-up.
