Rated 5 out of 5 stars

I've been using Firefox for a couple of years and my spelling is awful but the built in spell checker is US English which isn't English at all! all the spellings are wrong and I have no idea how Americans can actually say they speak English because they don't it's American so I'm so very thankful I found this add-on , I just wish I'd found it ages ago as it would have saved me alot of stress .

This review is for a previous version of the add-on (1.19.1).
