Rated 5 out of 5 stars

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 (1.3.2.1-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.
