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.

This review is for a previous version of the add-on (2.0.0). 

Thanks for your feedback. What do you expect a "spell checker" to do? "Kannada" is an Indian language if you don't know
