Rated 5 out of 5 stars

Pau- this extension changed my life, with only slight exaggeration. You have no idea how long I dreamed of something which would enable instant lookup for words in texts of the languages I'm learning (Arabic and French). I even tried and failed to script something useful myself.

Now update it to work with Firefox 3 (beta) dammit!

This review is for a previous version of the add-on (0.3.3).
