ImTranslator for Opera

Google Translate for Opera

If you believe that the Google translation service translates better, or if the languages you frequently use are supported by the Google Translate service only, you'd better use the Google Translate extension for Opera, than ImTranslator extension.

But if you used to ImTranslator extension for Opera, and still want to use Google Translate service only, you can disable "other translators" in ImTranslator Options (clear "Enable other translators" checkbox).
