5 Best Mozilla Firefox VPN Addons That Actually Work in 2021

A VPN is an amazing software tool that encrypts your data and lets you browse the web securely.

But did you know that a lot of VPNs come with Firefox extensions?

For those of us who prefer to use Firefox, having a VPN extension is a must. Instead of minimizing your browser, turning on your VPN, and then refreshing your web page, you can just click on the extension and know you’re protected.

In addition, if you only need to encrypt your traffic on Firefox, then there’s no point to turn on the software on your entire device. A Firefox extension uses much less data but still secures your internet activity.

Not all VPNs have an extension for Firefox though, and some of them work differently. We’ve rounded up the best VPNs with a Firefox extension and explain the pros and cons of each.

  3. Surfshark’s Firefox plugin offers the same great features as its apps.

5 Best VPN Extensions for Firefox


Small assortment of technological devices compatible with NordVPN.
  • Adblocker
  • IP leak protection
  • 60 locations

Over the past few years, NordVPN has made some major improvements, and one of them is the new add-on for Firefox. This add-on is super lightweight, meaning it won’t slow down your connection. It’s also incredibly easy to install and use, and it includes an ad-blocker that really comes in handy.

However, users should note that this is more like a proxy than a VPN. This means that your other internet traffic won’t be protected. On the other hand, if you’re just browsing the web, it’s so much more worthwhile to use the extension than to turn on the software for your entire device.
