Rated 5 out of 5 stars

OVE the dictionary, have been using it forever. Reliably catches my errors, I am American but work on a British convention website. Our Brits do not find errors in my work, so it definitely helps. Thanks Mr. Tyndall and Mr. Bartlett!

BIG THANKS to user hanfox for explaining how to activate it by highlighting a misspelled word and right-clicking, I couldn't find a menu to do it on the newer Firefox versions.

I do wish I could add customised words to it - I broke my older version using notepad to edit it, and had to reinstall. *blush*

On the old version I found I needed Firefox GB to make it happy, dunno if that matters to anyone.

This review is for a previous version of the add-on (1.19).
