Google Chrome is the most popular internet browser for a reason. It offers a sleek and intuitive experience and seamless integration of various features. Unfortunately, Chrome’s close ties to Google’s ecosystem and data collection practices make it one of the less private options available.

Installing a few browser extensions can provide adequate protection and privacy to Google Chrome users. But how do you know which ones to use? There are thousands to choose from and trying all of them out is both impractical and dangerous. Browser extensions can steal your personal information, inject malicious code, or even take control of your browser.

To tackle this challenge successfully, read this article, which will cover the top 18 tried and tested extensions that enhance the privacy and security of Google Chrome.

18 Best Security Extensions for Chrome

Before we start, it's essential to understand a few critical aspects of browser extensions:

  • Multiple similar extensions operating simultaneously can lead to conflicts, slowdowns, or unexpected behavior. Sticking with one reliable extension per category and function is generally a good idea.
  • Most extensions share common drawbacks. For instance, ad blockers can accidentally block vital trackers or necessary ads, disrupting a website's proper functioning. Furthermore, extensions can cause browser slowdown if they are outdated or not configured correctly.
  • If you plan to mix and match extensions, you should research their compatibility beforehand. Additionally, test for conflicts systematically by disabling one extension at a time and prioritizing essential extensions.

Here is our list of the top 18 browser extensions.

1. uBlock Origin

With over 10 million users, uBlock Origin is the most popular free and open-source ad blocker for web browsers.
