NordVPN May 2022

Apps Available:

  • Mac
  • IOS

Website:  www.NordVPN.com

Money-back guarantee: 30 DAYS

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. Plus, NordVPN runs all servers exclusively from RAM, never writing any data to a physical hard drive. This means all data is securely wiped whenever a server is rebooted.

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.


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

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.

3. ExpressVPN


Apps Available:

  • PC
  • Mac
  • IOS
  • Android
  • Linux

Website:  www.ExpressVPN.com

Money-back guarantee: 30 DAYS

ExpressVPN is a reliable, yet premium-priced, choice VPN for Firefox thanks to its dedicated browser add-on and impressive protection options.

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 an 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.


  • Comprehensive online security
  • Fast connections
  • Advanced location-spoofing
  • Unblocks Netflix, BBC iPlayer, and Amazon Prime

4. CyberGhost


Apps Available:

  • PC
  • Mac
  • IOS
  • Android
  • Linux

Website:  www.CyberGhost.com

Money-back guarantee: 45 DAYS

CyberGhost VPN offers a free add-on for Firefox, delivering basic security, which is a plus for users who don’t have much experience with using a VPN.

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 7,500+ servers, located in 90 countries, meaning U.S. Netflix and other streaming sites are available when you connect to a server in the corresponding country. (If you use the browser extension on its own, you have access to only 8 servers in 4 countries.)

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.


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


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

GREAT VPN FOR BEGINNERS:CyberGhost works well with Firefox and provides great connection speeds. The free Firefox add-on can leave users vulnerable to certain security threats. However, beginner VPN users will appreciate its ease of use. 45-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.


  • Firefox extension
  • Unblocks Netflix
  • Fast speeds


  • Firefox add-on does not offer full security of desktop app
  • Small global server network

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.

Firefox VPN FAQs

What Is the Best Free VPN for Firefox?

You want to avoid free VPNs at all costs. Free VPNs have a habit of throttling your connection speeds, imposing data limits on your usage, making you wait in a queue before connecting and selling your data to interested third parties. To stay safe on the web, I would highly recommend keeping to paid VPN providers.

What Is the Fastest VPN for Firefox?

ExpressVPN offers the fastest connection speeds I've ever seen from any provider. No matter what your regular connection speeds are, ExpressVPN won't slow them down by much.

Should I Use Mozilla VPN?

Mozilla offers a reasonably priced VPN solution that offers good encryption. It offers 280+ servers in 30 countries, and it claims to keep no logs of any kind. Still, you can find providers that offer much more bang for your buck for a similar price.
