Best Porn Blocker Chrome Extension
The best porn blocker Chrome extension in 2026 is QuitPorn: Free Porn Blocker. It is completely free with no limits, blocks adult sites in normal and incognito tabs, blocks every .xxx site out of the box, keeps SafeSearch on, and blocks any extra site or word you add. No account, no ads, and nothing is sent to us.
Like every Chrome extension, it can be switched off. If you need a block that can't be, use the QuitPorn app, which locks your phone and computer for 1 to 365 days. More on that below.

What No Chrome Extension Can Do
Every extension, including ours, can be removed or switched off from Chrome's extensions page. It also only covers Chrome. Other browsers and the apps on your phone stay open.
If you have switched blockers off before, use the QuitPorn app. It blocks porn in every browser and app on iPhone, iPad, Android, Windows and Mac, for 1 to 365 days, and nobody can end the lock early, including you and our support team. Start with the free extension, and move to the lock when you need it to hold. See how to block all porn sites.
How to Install It
- Open the QuitPorn extension in the Chrome Web Store and click Add to Chrome.
- Agree to the short notice on the setup page.
- Switch on "Allow in Incognito" when the setup page shows you where.
- Add any extra sites or words you want blocked.
