Choosing a VPN for Firefox doesn't have to be difficult. In this article, I rank the top best VPNs for Firefox, reviewing their privacy and security protections, connection speeds, browser extensions and more.

As of March 2022, Firefox ranked as the 4th most popular web browser according to stats gathered by W3Counter. If you’re one of the millions of users of the Mozilla software, you may be wondering, what is the best VPN for Firefox in 2022?

While Firefox already offers some great security features and add-ons that allow you to block ads and pop-ups, as well as manage cookies, it’s likely you will still want to improve your safety online by using a quality VPN.

Can a VPN Help?

A quality VPN for Firefox can help to keep your data secure, allow access to geo-blocked content, and prevent cybercrime, such as hacking, ID theft, and fraud. In this article, we’ll cover the best VPNs for Firefox, based on our extensive testing.

1. NordVPN

NordVPN May 2023

Apps Available:

  • PC
  • Mac
  • IOS
  • Android
  • Linux

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, protecting only your in-browser activities while the rest of your apps use your unprotected connection.

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. You can even use split tunneling to exclude selected websites from using the VPN’s encrypted tunnel.

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. It should be noted that the extension only allows connecting to servers in the United States, Canada, the United Kingdom and Germany.

NordVPN also provides native app support for macOS (with native M1 Mac support), Windows, Linux, Android, iOS, Android TV, and Amazon Fire TV. In addition to Firefox, browser extensions are also available for Chrome and Edge browsers. Router support also makes the scene.

The provider has more than 5,400 servers stationed in 60 countries around the world. Its owned-and-operated servers keep outside contractors aways from NordVPN customers’ personal data.

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 encryption
  • Fast download speeds
  • Reliable support


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

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.

As well as Firefox extensions, the provider also offers native app support for your Android, Android TV, iOS, Linux, Windows, macOS, Chromebook and Amazon Fire devices. Chrome and Edge browser extensions are also available, as is extensive support for numerous router models.

The provider’s connection speeds are some of the fastest around, providing plenty of no data cap bandwidth for your favorite online activities.

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

4. CyberGhost


Apps Available:

  • PC
  • Mac
  • IOS
  • Android
  • Linux
  • FireTV

Website:  www.CyberGhost.com

Money-back guarantee: 45 DAYS

CyberGhost 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. Also, it should be noted that the free Firefox access is limited to the United States, Romania, The Netherlands and Germany.

Alongside its Firefox extension, the provider also offers an extension for the Chrome browser. In addition, native app support is available for Android, iOS, Linux, macOS, Windows, Android TV and Amazon Fire TV. Router support is here too.

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 five 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 eight servers in four 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.

The provider also offers other security and privacy-related services, including a password manager, alerts if and when your email address is exposed in a data breach, a security suite for Windows which includes antivirus and malware protection, a privacy customization app and more.


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


  • Free add-on doesn’t cover every security threat
  • Limited to four 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. Has a 45-day money-back guarantee.

Methodology for Assessing VPNs for Firefox

While Firefox offers some excellent online privacy features, it doesn’t change the fact that browsing the web can be dangerous. The categories below are what I consider when ranking VPN providers for use while with Firefox:

  • Firefox compatibility: While a VPN definitely gets bonus points for offering a Firefox extension, it isn’t necessarily a must, as even the two providers on my list that don’t offer extensions offer apps that can be used to protect your Firefox browsing sessions.
  • Security and privacy: Arguably the most important consideration for a VPN, as a VPN should protect its users’ connections with (at the very least) banking-level encryption, a kill switch and DNS/IP leak protection. VPNs should never save any logs related to your online activities. All of the VPNs on my lists offer this, and more.
  • Connection speed: A slow connection speed can make a browsing session be really frustrating. The less a VPN slows down your connection the better. None of the VPNs on my list will slow down your connection to an irritating level.
  • Value: A VPN should never ask for a price out of line with the feature set it offers. All of the VPNs on my list deliver a good value for the asking price.
  • Ease of use: Ease of use is an important factor to consider, as you’ll likely be jumping on and off your browser during the day. The VPNs on my list offer easy-to-use apps for most popular connected device platforms.
  • Server network: A large global server network provides access to geo-controlled content around the globe. Also, it’s a bonus when a provider has a large number of servers in individual locations, which helps prevent individual servers from being overloaded with users, harming its performance.
  • Streaming: Streaming video is arguably one of the most popular activities among VPN users. That means any VPN worth considering will offer access to multiple streaming services. Most VPNs that I include on my lists deliver reliable access to many popular streaming sites, such as Netflix, Amazon Prime Video, Hulu and others.

While the above list may seem detailed, the research does not end here. The factors above are just a small bit of what I research with my comprehensive VPN testing methodology. This data-centric approach means I can better understand VPN providers and their services.

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.
