Almost a perfect replacement for Google Translate, almost. Rated 4 out of 5 stars
This add-on does just what the one in Chrome does. Nice! One little thing, though. Why does it have to be sooo ugly? The Chrome one uses my theme. This doesn't and the icons and the "Google" text are out of focus. I went into the gtranslator.jar file and changed the icons to something more appealing. Would love to do the same for the toolbar too but haven't figured out how to do that. This would get five stars if the ap followed a person's theme.
