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.

How to block a website on Opera using a web filter extension

If you don’t want to install third-party apps, then there is another way to block websites on Opera-adding extension. But what I have to say is that the extensions can be easily removed. So if you want to block a website on Opera to control your child’s online behavior, this is not the safest way. Below I’ll show you a web filter extension that can be added to Opera/Opera GX-Block Site.

1. Open the Opera browser on your computer.

2. Click the 3-dot icon in the bottom left corner. Under Sidebar Extensions, select the Add button next to Add more.

Bonus tip: Use Opera's Content settings to block certain elements on websites

Opera browser has no built in features to block a website directly, but allows you to specify if a website can set cookies, use JavaScript, show images, send pop-ups or use redirects. Below I’ll show you how to set YouTube website to not show images in Opera.

1. Open the Opera browser.

Conclusion

Our kids are always affected by inappropriate websites on the Internet such as porn sites, games sites. Also, we are easy to get distracted by some interesting websites such as social media when working. It’s necessary to find a way to block unwanted websites. To block a website on Opera/Opera GX, I think the best way is to install 3rd-party web blocker apps such as AppCrypt. If you choose to add extensions, the blocking can be bypassed easily. And Opera’s built-in settings can’t block a website completely.
