Block websites on Opera GX by categories

Opera especially Opera GX is a browser preferred by gamers. Features like CPU, RAM and Network limiter enhance their gaming experience.

Block websites on Opera at certain times

If you just want to control the time you/your kids spend on certain websites, you can set a schedule to a specific website. Then this tool will only block this website during the time you set. And can be accessed normally at other times. To do that, find the site from your block list. Click the clock icon on the left. Enable Custom Schedule then set the time. Alternatively, you can also set a general schedule to all blocked websites on your block list at certain times. The general schedule icon is on the top tool bar.

Our kids are always affected by inappropriate websites on computer such as porn sites, gambling sites. We are also easy to distract by some interesting websites such as social media sites when working. It’s necessary to find a way to block websites on computer. To block a website on Opera/Opera GX, I think the best way is to install 3rd-party apps such as AppCrypt. If you choose to add extensions, it will be easy to remove. And Opera’s built-in settings can’t block a website totally.
