Rated 5 out of 5 stars
Thanks for this intersting addon. It really does make Firefox feel more like an OS than a browser now! I like how you can copy and paste your own text and use it to practise typing. Once thing I would like to see on the next version though is a "0" option for automatic backspace as I like to manually correct my errors.This review is for a previous version of the add-on (3.5).
