If you have the feeling that your MacBook is getting slower and slower, too-much useless extensions are to blame. Many of us download extensions from unknown websites without even knowing it. As time goes by, these extensions continue to accumulate and thus result in the slow and annoying performance of your MacBook. Now, I believe a lot of people have this question: What are they exactly, and how to delete extensions?

There are mainly 3 types of extensions: Add-on, Plug-in, and Extension. All of them are software created to enable your browser to provide more tailored service and additional tools for you. That being said, they also differ in many cases.

What are the Differences among Adds-on, Plugins, and Extensions

Add-on is a type of software. It can extend the functionality of some applications. In other words, it can add extra functions in the browser so that the browser gives better performance.

The extension is used to extend the functionality of the browser just like Add-on. These two are basically the same, for they add various things into the browser to get the browser to perform better.

Plug-in is a bit different. It cannot be run independently and can only change something on the current web page. It can be said that Plug-in is not that powerful compared with Add-on and Extension.
