How to block adult video sites with browser extensions

Several browser extensions can block access to adult video sites, including Xvideo and similar platforms. The most widely used are Freedom, Cold Turkey, LeechBlock NG, and OpenDNS Home. Each works differently — some block by keyword or domain name, others by category, and some require you to manually enter site addresses. The extension you choose depends on whether you want a simple on-off switch, scheduled blocking during certain hours, or a system that requires a password to disable.

Most of these extensions work on Chrome, Firefox, and Edge. Some also run on Safari, though fewer options exist for Apple browsers. Installation is straightforward: you search the extension store for the tool's name, click "Add to browser," and then configure which sites or categories to block. The blocking happens at your browser level, meaning it only affects that specific browser on that specific device — it will not block sites on your phone or on a different computer unless you install the extension there too.

Key Takeaways

  • Freedom, Cold Turkey, LeechBlock NG, and OpenDNS Home are the most common extensions for blocking adult video sites on desktop browsers.
  • Extensions block at the browser level only, so blocking on Chrome does not affect Firefox, Safari, or mobile devices unless you install the extension separately on each.
  • Some extensions let you block by domain name or keyword, while others block entire categories and require a password to turn off the block.
  • Scheduled blocking (for example, blocking between 9 PM and 6 AM) is available in Freedom and Cold Turkey but not in simpler tools like LeechBlock NG.

Freedom: blocking with scheduled time windows

Freedom is a cross-platform tool that blocks websites and apps on Windows, Mac, iPhone, and Android. On desktop, you install it as a browser extension or as a standalone application. You can block Xvideo and other adult sites by entering their domain names into a blocklist, or you can block entire categories like "Adult" if the extension's built-in category system recognizes the site.

The main advantage of Freedom is scheduling. You can set it to block certain sites only during work hours, only at night, or on a recurring schedule. Once a block is active, you cannot turn it off without entering a password or waiting until the scheduled time ends. Freedom is not free — it charges a monthly or annual subscription, though it offers a trial period.

Cold Turkey: blocking with a lock-down mode

Cold Turkey is primarily a Windows and Mac application, though it has limited browser extension support. Unlike Freedom, Cold Turkey focuses on aggressive blocking: once you activate a block, you cannot disable it until the timer runs out, even if you restart your computer or uninstall the extension. This makes it useful if you want to prevent yourself from accessing a site during a specific window and want no way to override that decision in the moment.

Cold Turkey lets you block by domain name, keyword, or category. You can set a block to run for a fixed time (for example, two hours) or on a recurring schedule (for example, every weekday from 8 AM to 6 PM). The paid version costs a one-time fee rather than a subscription. The free version has fewer features but still blocks sites effectively.

LeechBlock NG: simple domain and keyword blocking

LeechBlock NG is a lightweight, free extension available for Chrome and Firefox. It does not require a subscription or account. You manually enter the domain names or keywords you want to block — for example, "xvideo" or "xvideos.com" — and the extension prevents your browser from loading those pages.

LeechBlock NG does not have scheduling built in, but it does let you set time-based rules: you can tell it to block certain sites only during certain hours of the day or on certain days of the week. It also has a "lockdown" feature where you can set a password that prevents you from disabling the block until a timer expires. Because it is free and open-source, it has no account requirement and does not collect data about your browsing.

OpenDNS Home: blocking at the network level

OpenDNS Home is different from the other tools because it blocks at your network level rather than just in your browser. You set it up on your router or through your internet provider's settings, and it blocks sites for all devices on your network — computers, phones, tablets, and smart TVs. This means someone cannot simply switch to a different browser or device to bypass the block.

OpenDNS Home uses category-based blocking, so you can block entire categories like "Adult" without manually entering individual site names. It is free to set up and does not require a subscription, though your internet provider may charge a fee if they offer it as a managed service. The downside is that it requires access to your router settings or your ISP account, and it blocks sites network-wide, so you cannot easily turn it off for just yourself.

Comparing blocking methods: browser versus network

Browser extensions block only within that specific browser on that specific device. If you use Chrome, Firefox, Safari, and Edge on the same computer, you would need to install the extension in each one. If you use a laptop and a desktop, you would need to install it on both. Mobile browsers like Chrome on iPhone or Android do not support most extensions, so blocking does not carry over to your phone.

Network-level blocking through OpenDNS or your router affects all devices and all browsers on your network at once. This is more powerful but also less flexible — you cannot easily block a site for yourself while allowing it for others on the same network. It also requires technical knowledge to set up, or permission from whoever controls the router.

For most people trying to block a specific site on a single computer, a browser extension is simpler. For families or shared networks, network-level blocking is more effective because it cannot be bypassed by switching browsers.

What happens when you try to visit a blocked site

When you navigate to a blocked site, the extension intercepts the request before the page loads. Instead of showing the adult content, it displays a blank page, a warning message, or a redirect to a different page — depending on which extension you use and how you configured it. Some extensions show a message saying the site is blocked; others simply show a blank page with no explanation.

If the extension requires a password to disable the block, you will see a prompt asking for that password. If you enter the wrong password, the block remains active. If you set a time-based block, the extension will not let you disable it until the scheduled time ends, even if you know the password.

Frequently Asked Questions

Can I block Xvideo on my phone with an extension?

Most browser extensions do not work on mobile phones. Chrome and Firefox on Android do not support most blocking extensions. Your best option on mobile is to use parental control apps like Google Family Link or Apple Screen Time, which block sites at the device level. Some phones also have built-in content filters in their settings.

What if someone uninstalls the extension to get around the block?

If you are the only person with access to your computer, uninstalling is a risk. If you set a password on the extension, they would need that password to disable it, but they could still uninstall it entirely. For stronger protection, use network-level blocking through your router or OpenDNS, which cannot be bypassed by uninstalling a browser extension.

Do these extensions slow down my browser?

Lightweight extensions like LeechBlock NG have minimal impact on browser speed. Heavier tools like Freedom or Cold Turkey may use slightly more memory and processing power, especially if they are running scheduled blocks or monitoring multiple categories. The difference is usually not noticeable on modern computers.

Can I block Xvideo on just one user account on my computer?

Yes, if you install the extension only in that user account's browser. Each Windows or Mac user account has its own browser profiles and extensions, so blocking in one account does not affect another. However, if someone has administrator access to your computer, they can create a new account or use a different browser where the extension is not installed.

Which extension is best for blocking during work hours only?

Freedom and Cold Turkey both support time-based scheduling. Freedom lets you set recurring schedules (for example, block every weekday from 9 AM to 5 PM) and requires a password to override. Cold Turkey has similar features and adds a "lock-down" mode where the block cannot be disabled even if you restart your computer. Both charge for this functionality.
