NOTICE This add-on does not work pending a bug and is therefore not available as an add-on for Firefox. Please, see the following alternatives:
END OF NOTICE
Based on the text entered in a textarea, this add-on automatically detects the language and sets the corresponding spell checking dictionary. You need to type at least 25 characters before the add-on will start. Before that limit is reached, it disables spell checking. A small icon on the extension's icon will give you feedback about the language that has been detected.
