How to set up Surfshark browser extension on Firefox?

In this tutorial, you will learn how to install and use the Surfshark VPN extension for Firefox browsers.

This is a quick and convenient way to use Surfshark VPN without installing the desktop app. It’s worth mentioning, that the Surfshark browser extension only covers the browser traffic. In other words, other browsers and apps outside of Firefox will use your regular network connection.

To follow instructions, you will need a computer with a Mozilla Firefox browser and an active Surfshark VPN subscription.

You will learn how to:
