Keeper WebPro personal certificate import in Opera

Opera uses the Internet Explorer certificate storage. This is why the certificate import procedure is identical to that for Internet Explorer.

The certificate manager can be called from the "Menu" - "Settings" -"Privacy and security" - "More" - "Manage certificates".
