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.
The App Store (or 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 App Store are reviewed, signed, and hosted by Apple. And all extensions that you install from the App Store update automatically.
To find extensions to install, open Safari and choose Safari > Safari Extensions from the menu bar.
- If you're using Safari 12, the App Store opens to the Safari Extensions page.
- If you're using an earlier version of Safari, Safari opens the Safari Extensions Gallery webpage.
Safari automatically updates extensions that were installed from the App Store with Safari 12, as well as extensions that were installed from the Safari Extensions Gallery with Safari 9, 10, or 11 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:
- Choose Preferences from the Safari menu, then click Extensions.
- Select Updates in the lower-left corner of the window. It appears only when updates are available.
- Click the Update button next to each update that you want to install.
Turn off or uninstall extensions
Choose Safari > Preferences, then click Extensions. For each extension, you can use the checkbox to enable or disable the extension.
If you can't determine what an extension does, or you don't expect to use it again, click the Uninstall button for that extension.
