Using this addon for months. Excellent interface and very useful. Kudos.

Limited demo of a paid app. The list of languages on the site is limited to "English, German, Spanish, French, Portuguese, and Dutch", which may make it appear that spell checking is not available in other languages. You cannot choose "EN-GB" or "EN-US", there is only some kind of "English" with the British flag. So the American language is not supported? Uses a third party sync, not a Mozilla account.

wow

If grammar and punctuation aren't your forte install this extension. Great tool
