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. Extensions are a great way to personalize your browsing experience.

Use the App Store to conveniently download and install Safari extensions. All extensions in the App Store are reviewed, signed, and hosted by Apple for your security.

  2. The App Store opens to the Safari Extensions page, as pictured above. To download and install an extension, click Get or click the price. You might be asked to sign in with your Apple ID.
  3. Click Install.
  4. After the extension is installed, click Open and follow the onscreen instructions provided by the extension.

Then return to Safari to turn on the extension you installed:

  1. Choose Safari > Preferences.
  2. Click Extensions.
  3. Select the checkbox next to the extension's name.

All extensions installed from the App Store are automatically kept up to date.

Safari no longer supports most web plug-ins. To load webpages more quickly, save energy, and strengthen security, Safari is optimized for content that uses the HTML5 web standard, which doesn't require a plug-in. To enhance and customize your browsing experience, use Safari extensions instead of web plug-ins.

While many sites have made the transition to HTML5 for video on the web, you may run into a site that requires older plug-ins such as the QuickTime 7 web plug-in in order to play some videos. While that plug-in has not been enabled by default since OS X 10.9 Mavericks, you can still enable it if you need to.
