Install and manage Safari extensions on your Mac

Safari extensions enhance and customize your browsing experience.

Safari extensions add functionality to Safari, so you can explore the web the way you want. Extensions can show helpful information about a webpage, display news headlines, help you use your favorite services, change the appearance of webpages, and much more. With developers bringing new extensions to the Safari Extensions Gallery every day, you can discover new ways to personalize your browsing experience.


Install extensions

The Safari Extensions Gallery lets you conveniently browse extensions and install them with a single click. It's the safest place to download Safari extensions, because all extensions in the Gallery are reviewed, signed, and hosted by Apple. And all extensions that you install from the gallery update automatically.

  1. Open the Gallery by choosing Safari Extensions from the Safari menu.
  2. Click “Install now" next to the extension that you want to install.

You can also get extensions directly from your favorite developers. When you download an extension from a developer, you get a file that ends with .safariextz. Double-click the file to install the extension. It isn't signed or hosted by Apple, so Safari asks you to confirm that you trust the source and want to install the extension.

Update extensions

Safari automatically updates extensions that were installed from the Safari Extensions Gallery with Safari 9 in OS X Yosemite or later.

You can manually update extensions that were downloaded from the developer or installed with an earlier version of Safari:

  1. Choose Preferences from the Safari menu, then click Extensions.
  2. Select Updates in the lower-left corner of the window. It appears only when updates are available.
  3. Click the Update button next to each update that you want to install. 

Turn off or uninstall extensions

  1. Choose Preferences from the Safari menu, then click Extensions.
  2. Select an extension from the list.
  3. Turn off the extension by deselecting the Enable checkbox. If you can't determine what an extension does, or you don't expect to use it again, click the Uninstall button.
