What is the best VPN for Firefox?

Firefox is the fourth most popular web browser according to W3counter usage statistics. If you are using Firefox and your VPN provider offers a VPN add-on, you may want to use it. It can be difficult to understand what features are and are not included in the Firefox add-on. Here are three of the best VPNs and what their Firefox VPN add-ons can do.


The Nordvpn Firefox extension is available for free here, although you will need a subscriber account for this to work. As with any browser-based VPN plugin, NordVPN is technically a proxy, as it only redirects traffic from the browser app, rather than the entire operating system like a VPN. Nord VPN is not just a proxy, it is an encrypted proxy. All connections through NordVPN’s Firefox extension are protected by the best 256-bit AES encryption available, just like with the standalone VPN app.

The Firefox add-on specifically includes support for CyberSec, which is NordVPN’s ad, tracker, and malware blocker. The plugin also blocks the WebRTC feature by default, which can reveal your real IP address, even when using a VPN.

The full lineup of over 5,200 VPN servers in 59 countries is available in the Firefox add-on, allowing for maximum flexibility, although you can only select a generic location rather than a specific server. You’re also covered by NordVPN’s strict no-logging policy.

Tip: It is generally recommended that you connect to a fast, nearby VPN server unless you need to connect to a specific location to bypass location-based access restrictions.

Prices start at $3.49 per month, for a three-year plan that covers up to 6 simultaneous devices.


The free Surfshark Firefox extension can be downloaded from here. Once you’ve installed the extension, you’ll need to log in to connect to any of the 1,700+ servers in 63 countries. When your VPN extension is connected, all your browser connections are encrypted with the AES 256-bit encryption algorithm

The Surfshark extension for Firefox does not support the full functionality of Surfshark. However, one of the key features included is CleanWeb’s ad, tracker, and malware blocker. Other features include a strict no-logging policy and a private DNS service, designed to prevent DNS leaks.

Prices for a Surfshark subscription start at just $1.99 per month, for a two-year plan that supports unlimited devices.


ExpressVPN Firefox extension is a little different from other VPN providers. Instead of functioning as a standalone VPN tool, the browser add-on is a configuration interface for the main ExpressVPN app. As such, it requires the installation of the main ExpressVPN app.

One of the advantages of the browser plugin being an interface to the full VPN client is that full VPN functionality is available. Plus, all of your device communications are protected, rather than just browser traffic.

The ExpressVPN Firefox add-on comes in 16 different languages, making it easy to use even for non-English speakers. It also blocks WebRTC to prevent it from revealing your real IP address while using the VPN.

Prices start at $6.67 per month, for a one-year subscription that covers up to five simultaneous devices.
