Best Browser Extensions for Privacy

Internet browsers are our key to accessing the Internet. But when choosing an Internet browser, it’s important to consider the level of privacy that the browser will offer you as a user. While not all browsers are created equal, browser extensions can help level the playing field by allowing users to customize their browsers with plugins.

There are so many browser extensions concerned with privacy that it’s easy to set yourself up for a safe and secure browsing experience. In this article, we’ll share some of the best browser extensions for every privacy concern.

How do browser extensions work?

Browser extensions are tiny pieces of software that change a user’s experience on a website or with information from a website. Browser extensions apply filters, block content, and add features all to customize a user’s Internet experience.

To use a web browser extension, the user downloads it onto their browser—either from a third-party software company or from the browser itself—and the extension will start to perform its designated tasks within the browser. They can be used for increased privacy, preventing ad tracking, ad blocking, finding the best online shopping deals, and everything in between.

Different browser extensions offer different levels of privacy.

The extensions suggested below work on almost every major browser, such as Google Chrome, Microsoft Edge, and Apple Safari. However, check with your browser by getting an open tab and going to your browser's home page. You should be able to find out if it can support extensions or not; most browsers do.

Privacy Badger

Privacy Badger is an extension that prevents third-party trackers from collecting information about users and their online activity.

This means that the extension blocks more trackers than other extensions and protect more securely against hidden threats to your personal information and device.

Privacy Badger does not specifically block ads. However, by blocking hidden trackers, the extension subsequently does cut out a lot of unnecessary and unsafe advertisements.

ExpressVPN is a well-known virtual private network service, but it also offers the ExpressVPN browser extension for improved privacy when using your browser.

How to safely add browser extensions

Although the purpose of browser extensions is to improve your Internet experience, malicious browser extensions will do the opposite. In order to safely add extensions to your browser, make sure you thoroughly research the extension before downloading it. Ensure that the extension, as well as the site you’re downloading it from, is legitimate and safe.

Make sure to follow the extensions’ instructions when downloading them to your browser. To ensure that you download legitimate versions, try to download extensions only from the extensions’ websites or from your browser’s app store, like the Chrome Web Store.
