Rated 5 out of 5 stars

I've posted an updated version (working with Firefox 9) here: https://addons.mozilla.org/en-US/firefox/addon/dictionarysearchupdated/

I'll try to push updates within a day or so of new stable releases of Firefox. Many thanks to the original author.

This review is for a previous version of the add-on (7.0.0).
