Rated 5 out of 5 stars

Great Addon, works very good with Firefox4 (German/English).
one suggestion: Is it possible that the icon would be directly over the text field? That would make selecting much easier, if the automatic language is wrong.
@satvic: you need to activate the new addon bar (strg+/), which is kinda the same as the old status bar.

This review is for a previous version of the add-on (1.0.1.1-signed.1-signed).
