I contacted Rapport and they advised me today they have no plans to include Opera - this is their quote
Thank you for contacting Trusteer Technical Support.
Please be advised that support for Opera, Google Chrome for Mac, Safari for Windows and additional browsers may be incorporated in future releases of Rapport, but unfortunately there are no immediate plans of this kind.
