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. However, spending too much time playing games can be damaging, especially for young kids. Cisdem AppCrypt can help you block websites by categories on Opera/Opera GX, like games sites, porn sites, gambling, and more. For example, to block all popular games websites on the Internet, click Import on the upper right corner. Choose Games Sites.
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.

AppCrypt provides 2 modes. You can add unwanted websites to block list, or block all websites with 1-click and then approve a few. Enable Block all websites button on the bottom left. Click on Exceptions next to it. Add the websites that you allow access to the Always Allow list. Then all websites except a few that you approved will be inaccessible on Opera.

If you don’t want to install apps, there is another way to block websites on Opera-adding extension. But what I have to say is that the extensions are easy to remove. So if you want to block a website on Opera to control your child’s online behavior using extension, this is not the safest way. Below I’ll show you an extension that can be added to Opera/Opera GX-Block Site.
1. Open Opera browser on your computer. Click the cube icon from the left side bar.
2. Click Get more extensions.
3. Search for Block Site from the new window. Choose the one with 3 “W” in the icon from the results.
4. Hit Add to Opera then Installing.
5. Enter the website that you want to block on the Opera browser. Now we navigate to the YouTube website.
6. Click the cube icon from the upper-right corner. Then hit on Block Site.
7. A prompt window will pop up. Click OK.
8. Now YouTube website is blocked on Opera. Next time whoever try to access this website, can only see this blocked window.
9. To remove this extension, you can click the cube icon on the upper-right corner of the window. Then click the 3-dot icon besides the Block Site. Select Remove extension.
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 not showing images on Opera.
1. Open Opera browser on your computer.
2. Click Settings on the left side bar menu.
3. Click on Advanced > Privacy & security> Site Settings.
4. Go to the Content section. Select Images.

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.

Both methods are useful. Thank you！And I think the web filter app would be better as it also works on Chrome and other browsers.
