How to add, see and delete Safari extensions on our Mac

The Safari app on our Mac comes with a large number of options and functions, such as the reading list, the autocomplete of passwords, tools to protect our privacy, etc. But what if we want more? Then we install extensions, small additions to Safari that third parties develop to provide more functionality. These extensions can be easily added and removed, let’s see how to do it.

How to check the extensions we have installed

Before adding or removing anything, let’s start with see what extensions we have installed in Safari. The steps are very simple:

  • We open the Safari app on our Mac.
  • In the Safari menu we choose Preferences.
  • We enter the Extensions tab.
  • Here in the left sidebar the list of all the extensions that are installed in Safari appears. Each of these extensions has a tick to its left that tells us if it is activated or deactivated.

    In the right part of the window, once we have selected a specific extension from the list, the information about the extension itself appears. In addition to the name and version, which appears at the top, we see what permissions the extension has, which is very important for our privacy.

    How to remove extensions from Safari

    Well, we have already seen what extensions we have installed, now we are going to delete them. The process is very simple, again:

  • We open the Safari app on our Mac.
  • In the Safari menu we choose Preferences.
  • We enter the Extensions tab.
  • We select the extension that we want to remove and on the right side we touch the Uninstall button. Alternatively, for example if we want to check if we need a certain extension, we can click on the tick to its left to deactivate it. Later if we see that it is not necessary we can eliminate it. Sometimes, when the extension depends on an app, Safari will inform us about it and offer us Show in Finder. Tapping it will open Finder in the Applications folder with the app selected from where we can drag it to the trash and enter the administrator password if requested.

    How to add extensions to Safari

    Once the cleaning is done, we can add certain extensions that give our Safari more and more functions. Safari extensions can be downloaded as files from various pages on the web, although, unless we have full confidence in the developer and check download hashes and file integrity, it is best to go to the App Store.

    In the App Store we can find a multitude of extensions which, like all content in the store, has been reviewed by Apple to ensure that it does not contain any harmful code. Let’s see how to do it:

  • We open the Safari app on our Mac.
  • In the Safari menu we choose Safari Extensions.
  • We will automatically see that a Mac App Store window opens listing various extensions. We can get any of them by tapping Get. As soon as it has been downloaded, we will see that Safari alerts us with a banner, at the top, in which we can touch Activate and review.

    That easy. Do we need to do more with Safari? With these steps we can add new extensions, review the ones we have installed, as well as eliminate those that we no longer need or at least deactivate them until we are sure.
