Change Extensions settings in Safari on Mac
In the Safari app on your Mac, use Extensions settings to change how you use extensions installed on your Mac.
To change these settings, choose Safari > Settings, then click Extensions.
Safari extensions are software programs you can install to customize the way your browser works. For example, extensions can show news headlines in a bar below the toolbar, change the appearance of web content, or add buttons to the Safari toolbar.

Share across devices
Make the extensions installed on your Mac available to any other Mac, and to any iPhone or iPad that supports the extension, where you’re signed in with the same Apple ID, have Safari turned on in iCloud settings, and have two-factor authentication turned on.
Open the App Store, where you can find Safari extensions to install.
Note: To provide some features, extensions may access the content of the webpages you visit. It’s good practice to check which extensions you’ve installed and make sure you’re familiar with what they do.
