How to Delete Chrome, Safari, Firefox, and Opera Extensions on a Mac

Browser extensions are great as they help us to block ads, personalize the app, 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.

  1. In MacKeeper, select Smart Uninstaller
  2. Click Start scan

In this article, we will learn how to delete browser extensions in:

Are you ready? Let’s dig in.

What is a browser extension?

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


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


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