The Best Free Porn Blocker to Effectively Block All Porn Online

There is so much porn on the Internet. Everyone can easily access pornography content on various porn sites and even from some regular websites such as social media. Some sites do not have a strict adult content moderation. This leads to the proliferation of porn. 

Porn has negative effects on both brain and body, especially for minors. Is there any way to block porn on devices for free? In this article, I will recommend you the best free porn blockers for Windows, Mac, Android, and iPhone and also provide detailed usage guide, helping you create a healthy online environment for you and your family.

 

The best free porn blocker for Windows and Mac

Free porn blockers for computers are available as browser extensions. I tested a few highly rated ones and found the best ones: the Porn Blocker extension for Chrome and the ClearMind extension for Firefox. Let’s check them out and see how they work.

Porn Blocker

Provided by joinrelay.app, this Chrome extension is designed to prevent users from accessing porn sites and help them fight the urge to view content of such nature. It’s simple yet powerful, requiring little setup.

Below is how to use it.

Step 1. Go to Chrome Web Store.

Step 2. Search for the extension. Click it in the search results.

Step 3. On the page that opens, click Add to Chrome.

Step 4. Right-click its icon in the Chrome toolbar and choose Manage Extension. Turn on the switch next to Allow in Incognito.

It’s that simple!

From now on, if you or your children try to visit a porn site, it won’t open. Instead, a page will appear, telling you that access is blocked, which you can’t bypass even using Incognito mode. For those who still feel the urge, this page also provides a list of suggestions to help overcome it.

Note: The fact is that it’s easy to remove or disable an extension (e.g., Porn Blocker) from a browser (e.g., Chrome). If you or your child uninstalls the extension, porn will become accessible again. However, although Porn Blocker can’t create a very strong barrier, it’s still helpful, for example, for those with little knowledge about browser extensions or people who have willpower.

If you are looking for a more powerful tool to prevent access to porn on a Windows or Mac computer, you can use AppCrypt.

• Block porn sites (and other categories of sites, like gambling or social sites) with a click
• Filter URLs containing explicit words
• Prevent inappropriate words from being searched everywhere, such as on Google, YouTube, and X
• Let you add specific sites to the block list
• Apply blocking to browsers like Chrome, Edge, Safari, and more
• Lock unsupported browsers
• Protect blocking with a password

Here is how to set it up.

Step 1. Download and install AppCrypt.

Free Download Windows 11/10/8/7 Free Download macOS 10.12 or later

Step 2. When you open it for the first time, set a password.

If you are using the tool for yourself, ask someone else to set the password for you.

Step 3. Right click (or control click) its icon in the taskbar (Windows) or menu bar (Mac) and choose Open Main Window.

Step 4. Access the main window by entering the password.

Step 5. In the Web Block tab, do any of the following:

• On a Windows PC, click Block porn sites and choose Always Block; on a Mac, click Import and choose Porn Sites.
• Add specific porn sites and explicit words to the block list using the URL field and the Add button.
• Click Import and then TXT file to import your own list of sites.

Porn sites and pages will be permanently blocked on this computer.

Note for Windows users: In step 5, this porn blocker requires you to install an extension on your chosen browser(s). And you can configure AppCrypt Preferences so that this very extension can’t be removed or disabled by people who don’t know the password.

 

ClearMind

The Porn Blocker extension isn’t available for Firefox, but there’s an alternative, which is free to use too.

Step 1. Go to Add-ons for Firefox.

Step 2. Search for and install ClearMind.

Step 3. Click the Extensions icon in the Firefox toolbar. Click the settings icon next to ClearMind and then Manage Extension.

Step 4. Select Allow for Run in Private Windows.

Now porn is blocked on this browser. If one tries to visit a porn site, a page will appear indicating that this site is not accessible. Also, the page provides different tools to help users deal with the urge to watch porn, depending on how strong the urge is, which is thoughtful.
