ExpressVPN is my #1 choice VPN for Firefox thanks to its dedicated browser add-on and impressive speeds, even over long-distance connections.

A Firefox extension is included as part of the ExpressVPN package, but this is not a standalone product. For the Firefox VPN extension to work, users need to install the ExpressVPN desktop app for Windows or Mac alongside the Firefox add-on.

Once installed, the Firefox extension is simple and easy to use, and it’s easy to select a server from the available locations, set the VPN to connect on browser startup and obscure your IP.

The ExpressVPN Firefox offering can also help change your geolocation so you can access geo-blocked sites and content, such as U.S. Netflix, Amazon Prime and BBC iPlayer by connecting to a server located in the relevant territory.

When it comes to security, ExpressVPN offers military-grade 256-bit encryption along with a network-lock kill switch that shuts down your connection in case of unexpected disconnection from the VPN. With no logs or tracking of your browsing or data, privacy is assured.

Support comes in the form of 24/7 live chat and email assistance, along with a number of troubleshooting guides.

There’s no free trial with ExpressVPN, but there is a 30-day “no-hassle” money-back guarantee.

Pros

  • Very secure
  • Fast
  • Advanced location-spoofing
  • Unblocks Netflix, BBC iPlayer and Amazon Prime

Cons

  • Firefox add-on doesn’t work as standalone

BEST FOR FIREFOX:ExpressVPN is my #1 VPN for Firefox thanks to great content-unblocking options, secure and speedy connections, and a host of security features. Try it risk-free with their 30-day money-back guarantee.

2. NordVPN

NordVPN provides a standalone Firefox extension that you can use without installing the NordVPN app. The result is a lightweight alternative to using a full VPN service, with many of the same security features.

The NordVPN Firefox extension encrypts traffic, provides IP leak protection to protect data escaping the VPN tunnel and offers a CyberSec feature to block suspicious websites and prevent malware. You can also configure the NordVPN Firefox add-on to connect as soon as the Firefox browser launches.

When it comes to streaming popular services, such as Netflix, Amazon Prime and BBC iPlayer, the NordVPN Firefox add-on performs well and can unlock geo-blocked content.

If you decide to use the main VPN client, you’ll also get a built-in kill switch to protect your IP even if your VPN connection drops, as well as DNS leak protection to keep all information within the VPN tunnel, so that your ISP and eavesdroppers can’t see what websites you’re visiting.

There’s also military-grade 256-bit encryption, and with a strict no-logs policy, your privacy is assured.

The NordVPN website offers a decent knowledge base of articles, and you can access customer support live chat via clicking the “help” button. NordVPN says that customer support will reply to email support requests within 48 hours; however, typical responses are much faster than this.

The entry NordVPN subscription allows for 6 simultaneous device connections.

Pros

  • Firefox standalone plugin
  • Unblocks sites like Netflix and BBC iPlayer
  • Strong security
  • Reliable speeds

Cons

  • Specific server selection disabled in Firefox add-on (location only)

BEST BUDGET VPN:NordVPN is a great budget VPN option for Firefox users. The standalone plugin is easy to use and provides reliable speeds. 30 day money back guarantee.

3. CyberGhost

CyberGhost VPN offers a free add-on for Firefox, delivering basic security.

For more comprehensive features, such as protecting against Flash vulnerabilities and WebRTC leaks (where websites can request your IP address), users will have to pay for the full Mac or Windows version.

When it comes to security, CyberGhost does a good job of protecting your privacy, offering military-grade 256-bit encryption and a no-logs policy.

Like many other VPNs on this list, CyberGhost VPN includes DNS leak protection and a kill switch to mask your IP at all times.

Other positive features include the option to connect up to 5 devices simultaneously, as well as the option to automatically connect to the VPN when you start the desktop or mobile app.

If you’re looking to stream geo-blocked content, CyberGhost has 1,200 servers in 57 countries, meaning U.S. Netflix and other streaming sites are available when you connect to a server in the corresponding country.

CyberGhost offers an impressive range of guides for all platforms, including troubleshooting guides and several FAQs. However, the arrangement of these files can be difficult to navigate. Live chat support is also available and may deliver the fastest solution to any issues.

Pros

  • Free-to-use Firefox add-on
  • Strong security with desktop apps
  • Great speeds

Cons

  • Free add-on doesn’t cover every security threat
  • Limited to 4 server locations in free version

GREAT VALUE:CyberGhost works well with Firefox and provides great connection speeds. The free Firefox add-on can leave users vulnerable to security threats. 45-day money-back guarantee.

4. Surfshark

Surfshark offers a proxy extension that you can use on any device that supports Firefox.

The proxy extension delivers fast speeds, strong protection and access to geo-blocked content. Surfshark also supports streaming on sites such as Netflix, and allows torrenting and downloads without slowing down your online experience.

When it comes to security, Surfshark performs well with a no-logs policy, DNS leak protection to ensure your ISP can’t see what websites you’re visiting, and both IKEv2 and OpenVPN protocols, which deliver security and speed when transferring your data through the VPN. Surfshark is also very user-friendly and offers an easy download and setup process.

With over 800 servers in 50 countries, Surfshark doesn’t offer the most connection options on the list, but there should be enough choice for most users.

Other features worth noting include a built-in ad-blocker and unlimited simultaneous connections from all your devices to the VPN.

Support is available in the form of 24/7 live chat and email, and there’s a reasonable amount of documentation, with tutorials, setup guides and FAQs.

The Firefox extension and full app versions are covered by a 30-day money-back guarantee, so you can try Surfshark risk-free.

Pros

  • Unlimited connections
  • Fast streaming speeds
  • P2P-enabled
  • Unblocks Netflix

Cons

  • Fewer servers than some other VPN providers

EASY TO USE:Surfshark delivers access to streaming services, unblocks restricted sites (including Netflix) and offers a dedicated Firefox extension. Surfshark comes with a 30-day money-back guarantee.

5. SaferVPN

SaferVPN makes this list thanks to its Firefox VPN add-on, which delivers rapid surfing and streaming speeds.

While the standalone Firefox extension can’t provide the same levels of security as the VPN, it does use an HTTPS proxy for encryption of your data, it’s good for streaming content and gives access to sites like U.S. Netflix via its U.S.-based servers.

The main SaferVPN app provides strong security, with DNS leak protection to ensure that your IP address is always hidden and 256-bit encryption, which is military-grade. There’s also a kill switch, which turns off your internet access if you lose the VPN connection unexpectedly.

The provider also respects user privacy, with no connection or traffic logs recorded or connected to individual users. The basic plan allows for up to 5 simultaneous connections to the VPN.

SaferVPN provides 24/7 customer support via live chat or email, so there’s help on hand if anything goes wrong or you have technical questions.

Pros

  • Firefox extension
  • Unblocks Netflix
  • Fast speeds

Cons

  • Firefox add-on does not offer full security of desktop app

GOOD FOR FIREFOX:SaferVPN offers a Firefox extension, as well as a full app version with even more security features. The service offers rapid speeds and up to 5 simultaneous connections. 30 day money back guarantee.

What Is a VPN Add-on?

A VPN add-on, also called an extension, is an extra, browser-based solution that some VPN providers offer.

Nearly all add-ons are simpler, lighter versions of VPNs, which offer some but not all of the benefits of a full VPN.

The main reason people use VPN add-ons is for a lighter way to access geo-restricted content, and with faster speeds than with a full VPN.

What Kind of VPN Add-ons Are There?

It’s important to understand that the kind of proxy that each provider uses is different.

The two most common types of proxy that VPN providers use are HTTP or HTTPS.

An HTTP proxy allows you to connect to a website that is geo-restricted, but it doesn’t provide encryption or privacy for what you are viewing from your internet service provider.

I would always recommend that you use this kind of proxy alongside a full VPN for security and privacy.

On the other hand, an HTTPS proxy allows you to connect to geo-restricted content while also encrypting your data. Some HTTPS proxy extensions hide DNS requests, while others don’t, so you should check with your provider to confirm what is kept secure and private.

Should I Use a Firefox VPN Browser Extension or Full VPN?

Using a Firefox browser add-on or extension instead of a full desktop VPN or mobile app does not provide the same level of protection.

This fact means that Firefox extensions are not suitable for all users, such as those who are more concerned about their privacy or security. For others who are only worried about accessing geo-restricted content, a VPN browser extension may be sufficient.

Due to the security and privacy issues listed above, you’ll typically find that most VPN providers include the Firefox add-on as part of a more comprehensive VPN package, and that they encourage users to implement both.

Where possible, I would recommend that users sign up for a full VPN that provides access to Firefox add-ons alongside mobile and desktop apps. This way, you’re fully protected across all of your devices.
