In the "Invalid certificate" dialog box, the "Save selection for this certificate" checkbox is required, as it was in Opera 12.

I am pointing out the fact and ask to do.
This checkbox is not present. But really want to.

In the "Incorrect certificate" dialog, there is a very short checkbox "Save selection for this certificate" as it was in Opera 12

В диалоге "Ошибочный сертификат" очень не хватает чекбокса "Сохранить выбор для этого сертификата" как было еще в Opera 12
