How to Quickly Delete Extensions on a Mac

Browser extensions are great as they help us to block ads, personalize the browser, save passwords, and even correct our imperfect grammar. However, having too many of them can backfire. Think of extensions as small apps that open every time you launch your browser. Extensions need resources, so eventually, they will slow down your Mac and decrease its performance.

 

Fortunately, it’s reversible. In this article, we will learn how to delete extensions in different browsers:

  1. Google Chrome
  2. Safari
  3. Mozilla Firefox
  4. Opera

Are you ready? Let’s dig in.

What is a browser extension

Browser extensions are small programs that are designed to improve your browsing experience. Extensions can help you to personalize your browser by offering many great services such as ad blocking, interface modifications, cookie management, etc.

 

However, just because extensions are helpful doesn’t mean all of them are good. In fact, some extensions act as malware and steal your data, drain your resources in cryptocurrency mining, etc. Moreover, having lots of extensions will cause your MacBook to slow down and freeze.

 

Luckily, you can always remove suspicious or unneeded extensions from your Mac using this guide.
