Indeed a useful add-on, but I can't seem to get it work in gmail. In all other forms, it picks up my language after a few words, but not when typing an e-mail in gmail.
By the way, let me know if I can help with Swedish localization.

This review is for a previous version of the add-on (1.3.1.1-signed.1-signed).
