Get extensions to customize Safari on Mac
You can install Safari extensions to customize the way your browser works. For example, extensions can help you display social media and news buttons, block content on websites, give you access to features from other apps, and more.
Tip: The Mac App Store is the safest and easiest way to discover and install extensions. The extensions are reviewed by Apple, and they update automatically when Automatic Updates is selected in App Store settings.
