Rated 4 out of 5 stars
If the developer bothers to write a description of the extension, I will update my review. Until then, don't install something without having a clue what it does!
Edit: The Mobile AMO site looks very different than the desktop site. It doesn't list the extension as a dictionary/language pack, which is why I was unsure of its purpose. Sorry, I guess there is no way for me to delete this review.
