Opera and Opera GX do not include a built-in feature to block specific websites. For a quick option on a computer, use a web filter extension. For password protection, schedules, or blocking across multiple browsers, use a web filter app. In this article, we’ll show you several ways to block websites on Opera for Windows PC or Mac.

Tip 1: Block websites on Opera/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, gambling, and more. For example, to block all popular games websites on the Internet, click Import on the upper right corner. Choose Games Sites.

Tip 2: Block a website on Opera/Opera GX at certain times

If you just want to control the time you/your kids spend on certain websites, you can set a schedule. 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.

Tip 3: Block access to all sites except a few on Opera/Opera GX

This web filter app provides 2 blocking modes. It lets you add unwanted websites to block list, or block all websites on the Internet but allow a few. To use the latter mode, enable the “Block all websites” button in the bottom left corner. Click on “Exceptions” next to it. Add the sites that you allow access to the “Always Allow” list. Then all websites will be inaccessible on Opera except for the few you approved.

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

Best for: Users who want a free and simple way to block websites on Opera and do not need strong protection against bypassing.

If you prefer not to install a desktop app, web filter extension is a simple alternative. It works directly on Opera browser. It’s suitable for blocking a few distracting websites. 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.

In the following steps, we will use Block Site by raylothian. It lets you block specific websites, and block access to the websites at specified times and days.

1. Open Opera or Opera GX on your computer.

2. Click the 3-dot icon in the bottom left corner. Under Sidebar Extensions, click Add more.

Bonus tip: Can Opera’s built-in settings block a website?

No. Opera do not have a built-in feature that completely blocks access to a specific website. But Opera’s site settings 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.

2. Click the 3-dot icon. Click Settings icon on the sidebar.

    The AppCrypt method works great and blocks sites more effectively than extensions.

    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.
