Part 1. What are Mac Extensions?

Mac extensions are software features that are added to the browser, phone or the OS for extended or added functionalities. Extensions are made by third-party developers that are downloaded, installed and enabled at any time.

How does it work?

These extensions integrate with the browser for specific sets of tasks which let you discover new and fun ways to personalize browsing experience.

Like for example, if you are frequently using Amazon, you can install an extension which lets you browse or search at anytime. There will be a search bar added on the browser taskbar to let you conveniently use it at any time.

Another example for extensions is those pop-up blockers which are normally annoying whenever you open certain web pages. You can easily add an Ad-blocker to trap these pop-ups and will no longer bug you when opening new pages.

Part 2. How to Manually Enable or Disable Mac Extensions?

This is a paLike other software, extensions need to be downloaded or installed.

Extensions can be downloaded and installed using the Safari browser. This adds features, changes appearance, and ease of use of certain web pages.

1. Open Preferences from the Safari menu

2. Click Extensions

3. Find the desired extensions you wish to use.

4. Check or uncheck the Enable box

5.Install desired extension, If needed to uninstall, click the uninstall button

The steps to enable or disable Mac extensions are so easy, however, you have to do this every time you have new extensions to use on the browser.

You can also get extensions directly from the developers. Upon downloading an extension from the developer, you will see a file that usually ends with .safariextz. Double-click on the given file to install the extension.

These extensions are not signed or hosted by Apple, so Safari needs to ask you to confirm that you trust the source and want to continue the installation.ragraph

Part 3. Difference between Extensions, Plug-ins, and Add-ons

For non-technical people, it seemed that they are looking at the same exact thing when they hear about extensions, add-ons, and plug-ins. However, they are in fact different from each other in so many ways.

Let me define each of them so you won’t get confused the next time you see any of them.


We have already discussed extensions, its definitions and how to enable or disable it, so I’ll give you some popular extensions on Mac instead:

1. AdBlock

2. Web Clipper

3. 1Password

4. Save to Pocket

5. And Duck Duck Go

These are the most common Safari extensions which you normally see and use. Although we often mistake them to be part of the web browser, at least no we understood that these are called extensions which are separate entities from the Safari.


Add-ons are pieces of software that can be considered or similar to extensions. Like extensions, add-ons can do magical things on a web browser. They are used interchangeably at often times.


Plugins only add specific feature or content to an existing computer program and it does not affect the entire Safari browser. It doesn’t offer the same capabilities as extensions.

1. Adobe Flash Player

2. QuickTime Player

3. And Java

Plugins only affect an existing page and not the entire browser like how extensions work.

Part 5. How to Update Extensions

Just like the Safari browser itself, extensions need to be updated from time to time because developers also release new bug fixes and versions. The Safari browser automatically updates extensions that were installed from ‘Safari Extensions Gallery’ on those Mac running with Safari 9 in OS X Yosemite or the most recent.

You can also manually update the extensions that are downloaded from the developer or those extensions installed during an earlier Safari version.
