Safari, the default web browser for iOS and macOS, is full-featured and secure. Still, like many web browsers, it's possible to add additional functionality. In Safari 9 and earlier versions, Safari plug-ins helped users personalize their browsing experience. If you use a Safari version that's compatible with plug-ins, here's how to view and manage them.
Newer versions of Safari don't support plug-ins. Apple recommends that users explore Safari extensions to enhance the browser's functionality.
How to View Plug-ins in Safari
If you use Safari 9 or earlier, view your installed plug-ins from the browser's Help menu. Here's how to do this on a Mac:
Open Safari on your Mac.
Select Help from the browser menu at the top of the screen.
From the drop-down menu, select Installed Plug-ins.
A new browser tab opens, displaying detailed information on currently installed plug-ins, including the name, version, source file, MIME type associations, descriptions, and extensions.
How to Manage Plug-ins
Here's what to do if you need to modify any plug-in permissions:
Select Safari in the browser menu, located at the top of the screen.
From the drop-down menu, select Preferences.
The keyboard shortcut is Command+, (comma).
Select the Security heading.
Near the bottom of the Safari security preferences, uncheck Allow Plug-ins to stop all plug-ins from functioning.
To manage individual plug-ins, select Plug-In Settings or Manage Website Settings (depending on the browser version).
You'll see a list of current Safari plug-ins along with each website the browser currently has open.
To change a plug-in's usage settings, select the drop-down menu next to it and select Ask, Block, Allow (default), Allow Always, or Run in Unsafe Mode.
To disable an individual plug-in, remove the check mark next to it.
