Yes,there are various parental control app in Google Play Store. But they only support Google Chrome and the built-in browser. I want this feature specifically for Opera.

Opera must release a new feature on their browser- the "parental control" feature. As we all know a large number of kids and teens are now affected by porn videoes.Moreover,they are learning hacking,and misusing this knowledge.We all want safe platform for our kids. I believe opera developers seriously wants to ensure safe internet browser for all. It will be very helpful if opera developers release this feature with easy,user-friendly settings--Parents who want this feature enabled on their kids' smartphone,they can just simply create an opera account and choose what types of website they want to block and then sign out.
