Meanwhile, it appears that Opera has virtually no extension available which might replace what it ostensibly did--report on websites' reputations. There are also extensions/services--no on Opera--which do other safety checks. At this point, the only thing that I have been able to get to work is Avira Browser Safety, which does mark search results. Many of the alternatives (to WOT) won't work with Opera, even some Chrome ones (like Bitdefender TrafficLight). Many are free, if they work on your browser. Is Opera coming up with its own solution, and that is why there is nothing in the extensions "store?"
