HOW TO Install an ad blocker
1 Choose your weapon
Apple’s own Browse Better collection contains a good selection of ad blockers, although it’s only a small selection. To find out what each app does, click on its name and you’ll be taken to its App Store page.
2 Install the app
Installing Safari extensions works just like installing any other App Store app. When you open Safari, you’ll see a message at the top of the main window asking if you want to enable your new extension.
3 Adjust its options
Your ad blocker will appear as an icon near the address bar. Clicking on it will open the extension; here that means seeing what options are enabled and whether the site is trying to invade your privacy.
