How to block YouTube ads
Updated over a week ago

1Blocker Scripts is a 1Blocker extension available in the app on iOS and macOS devices, and it lets you block ads on YouTube in Safari more effectively. It uses additional tools that differ from the content-blocking technology used by the rest of 1Blocker's extensions.


1Blocker Scripts is available starting from 1Blocker 5.0 on iOS and 1Blocker 4.0 on macOS, and you can find it in the 'Extensions' section of Safari if you are running iOS 15+ or macOS 10.15.6+.

The new tool requires additional permission that Safari requests when you activate 1Blocker Scripts. We put your trust and privacy before anything else and use the new extension only to perform advanced content blocking in Safari. Even though 1Blocker Scripts requires these permissions, we will never use them against our users. We are always open to your feedback and questions if you have any doubts. Also, the extension is optional, and you can deactivate it at any moment.

How to enable 1Blocker Scripts:

On iOS:

1) Go to iOS Settings > Safari > Extensions

2) Locate 1Blocker Scripts in the list of Safari extensions

3) Turn 1Blocker Scripts on

4) Make sure that the extension is allowed on all websites

Alternatively, you can manage the extension right from Safari:

1) Launch Safari and open any website

2) Tap the 'aA' button on the left side of the address bar

3) Go to Manage Extensions

4) Turn 1Blocker Scripts on

On iPadOS, there's a separate puzzle icon that manages web extensions right from the Safari address bar. So, the Manage Extensions section is located here on iPads.

On macOS:

1) Launch Safari

2) Go to Safari > Settings...(shortcut: CMD+,) > Extensions

3) Enable 1Blocker Scripts

4) Make sure that the extension is allowed on all websites

Once the extension is enabled, you can manage its permissions from Safari > Settings > Websites > Extensions > 1Blocker Scripts.
