This is a very useful add-on. However in new versions of Firefox the dictionaries are not longer recognised. A fix would be great and very much appreciated.This review is for a previous version of the add-on (22.214.171.124-signed.1-signed).
Please read the workaround on the extension page
Also, next time please contact the author for bug reports and requests before using the reviews for that.
