English or American Spell check options ? Rated 3 out of 5 stars

I really need an ENGLISH spell checker not American please tell me if this has an English speller checker option . The native Firefox spell checker is no good for me because it's American and all the spellings are wrong . I tried emailing the Im Translater support email address but my email doesn't get through so that's why I'm asking here. It drive me crazy all the popular spell checkers cover loads of countries but not England! they say we do have English spell check but they don't, anyone who actually lives in England and speaks real English knows that English and American word spellings are quite often different.
