Review for United States English Spellchecker by Jimbir
Rated 5 out of 5 stars
This is a great add-on! Allows you to check your spelling on sites that don't have their own checker. I simply hit the install button and the thing started working immediately.
This review is for a previous version of the add-on (7.0.1).To create your own collections, you must have a Mozilla Add-ons account.
