An excellent add on, no more American English spell checking for me, Once you have installed this add on you also have to set it as the default language, to do this, on a web page with a text box, like a forum or similar, type enough text to activate the spell checker, then right click in the box and choose 'language' and select your preferred one in the list of installed ones.

@Meg you should have the same option/method in your email client, but you will have to start typing out an email before you can change to a preferred language it doesn't have an option in the menus, which is where we all look first.....
