Rated 4 out of 5 stars

This add-on is compatible with FF 11 and 12, and I really like the idea. Unfortunately, I have to keep on right-clicking in text boxes and then selecting NZ English as my language. 4 Stars (sorry if the right-click thing is not to do with your add-on).

This review is for a previous version of the add-on (1.0.1).
