As you probably know already, most of the websites you visit use unobtrusive tracking services to monitor your online behavior. Mozilla Firefox, much like other web browsers, shares information  — like your IP address — thus aiding the websites, advertisers and data brokers in tracking you. If you want to stay secure online and keep your personal information protected, you have to use the best VPN for Firefox.

Key Takeaways:

  • ExpressVPN’s Firefox add-on is the best service if you want to encrypt all network traffic.
  • NordVPN’s Firefox extension doesn’t give you all the features of the native apps. However, it still packs a nice array of features, making it the best to encrypt Firefox browser traffic.
  • Surfshark’s Firefox add-on gives you all the native Windows and macOS app features at a rock-bottom price. 
  • Windscribe is the best free VPN for Firefox, and it’s reliable, too.

As you’ll find out in a bit, it encrypts all your network traffic, keeping your data protected while concealing your digital footprint. 

This doesn’t mean the other VPN add-ons on the list are fly-by-night. Each VPN has its unique aspect, so keep reading to find out which service is best suited to your online privacy and security needs.

Mozilla also makes a VPN called, appropriately, Mozilla VPN. However, this VPN is currently available in only six countries–the U.S., UK, Canada, New Zealand, Singapore and Malaysia–which means it’s not quite ready to earn a spot on this list. Read the full Mozilla VPN review here.

What Makes the Best VPN for Firefox

Today’s VPN market offers a bewildering array of Firefox VPN extensions. Some add-ons are reliable, while others aren’t. Without predefined selection criteria, it’s difficult to separate the wheat from the chaff. We’ll show you what to look for in VPN add-ons for Firefox, but first, here is our short list of the best Firefox VPN extensions.

  1. ExpressVPN — Full VPN add-on with fast speeds
  2. NordVPN — Lightweight add-on that provides advanced privacy features
  3. Surfshark — Affordable VPN service with advanced privacy tools
  4. Windscribe — Solid free plan with unlimited simultaneous connections
  5. Private Internet Access — Easy-to-use VPN that offers fingerprinting protection

First and foremost, a good VPN for Firefox should be as easy to use and navigate as the browser itself. Every process — from setting up the VPN extension to using it — should be a cinch. The VPNs below have proven themselves on this front.

The VPN should also provide top-notch security and privacy, encrypting all of your network traffic and providing protection for high-risk online activities such as circumventing strict censorship and torrenting.

Lastly, if you’ll be downloading torrents or accessing streaming services such as Netflix and BBC iPlayer on Firefox, you need a super-fast VPN extension. Fast speeds allow you to enjoy a smoother streaming experience without buffering or poor picture quality.

While not all the VPNs below made it onto our fastest VPN list, they’re all fast enough to support your internet activities on the Firefox browser. Check out our VPN features guide to find out what other features can be included.

The 5 Best VPNs for Firefox

Mozilla Firefox is one of the most secure web browsers out there, as you can read in our Firefox review. However, on its own, the web browser isn’t 100 percent foolproof, and it takes an excellent VPN to fully realize its security and privacy potential. ExpressVPN is our top Firefox VPN, so let’s dive straight in.

1. ExpressVPN

ExpressVPN has one of the best add-ons for Firefox

More details about ExpressVPN:


  • Fast speeds & reliable connections
  • Extension has full ExpressVPN capabilities
  • Intuitive user interface
  • Excellent security


  • Pricey

ExpressVPN is our number one VPN for Firefox because it offers a full-featured VPN extension. The Firefox extension is unique because it isn’t a stand-alone browser plugin for Firefox. In other words, you have to install the ExpressVPN app for the extension to work. Doing so allows you to connect, disconnect and tinker with the native ExpressVPN app’s settings right from your Firefox toolbar.

The ExpressVPN Firefox extension gives you blazing-fast speeds, unlimited bandwidth and unparalleled ability to unblock streaming services such as Netflix, Hulu, BBC iPlayer and Amazon Prime. With strong 256-bit encryption, a strict no-logs policy, kill switch and DNS leak protection, the add-on guarantees top-notch digital security and privacy.

The ExpressVPN add-on uses an array of security features to encrypt and protect all of your network traffic — not just the traffic from your browser. It sets your HTML5 geolocation so that it matches the IP address of the server location you’re connected with. This way, it prevents the Firefox browser from revealing your true IP address and whereabouts to websites that you visit.

ExpressVPN is one of the best VPNs for Firefox.

The ExpressVPN Firefox extension is free to download and install, but you have to subscribe to a paid plan to access the features. The plans are pricey, but you can bring the cost down if you opt for the annual plan, which offers a 35 percent discount. On top of that, you’ll get three extra months free, and there’s a 30-day money-back guarantee. You can read our ExpressVPN review to learn more.

ExpressVPN is without a doubt the best Firefox VPN, thanks to its comprehensive set of features and ease of use. It seals all privacy and security vulnerabilities on Mozilla Firefox, allowing you to browse the internet, stream or torrent with confidence that no one can log your activity or steal your data.

2. NordVPN

The NordVPN Firefox add-on has a clean user interface.

More details about NordVPN:

  • Pricing: $3.49 per month (two-year plan)
  • Provider Website:


  • CyberSec feature blocks ads & malware
  • Lightweight Firefox extension
  • Extensive server network


  • Doesn’t offer all features of the native app

NordVPN is our second VPN for Firefox browser, and it only trails ExpressVPN because its add-on isn’t quite as fleshed out. It’s a stand-alone add-on, and you don’t have to install the NordVPN app for the extension to work. The extension is lightweight and doesn’t slow down your connection, making it a worthwhile option for high-speed activities, such as torrenting or gaming. 

However, NordVPN the Firefox extension encrypts only your Mozilla Firefox traffic. That fact aside, the extension is as easy to use as the native app itself. The UI is clean and intuitive, and it offers features such as the location search to improve user experience. With the plugin, you can connect to any of 5,400 NordVPN’s servers and enjoy unlimited bandwidth for unfettered streaming or torrenting.

Use NordVPN’s Additional Privacy and Security Features 

By default, the extension blocks WebRTC — a browser’s communication protocol that may leak your IP address. You can also enable the CyberSec feature to block pesky ads and block access to malicious websites. What’s more, the add-on offers extra protection from IP leaks, ensuring your data never gets exposed.

NordVPN Firefox is easy to use.

NordVPN is a budget-friendly VPN, and it’ll cost you $3.49 per month on the two-year plan to enable the Firefox extension. Even though there is no free trial, you get a 30-day money-back guarantee to test the Firefox add-on features. Read our NordVPN review to learn more.

In a nutshell, the NordVPN extension for Firefox doesn’t provide all the features of the native apps. However, it does come with all digital privacy and security features, including advanced tools to stop WebRTC leaks. Besides, its ability to unblock streaming services — such as Amazon Prime Video, Netflix, Hulu and BBC iPlayer — is unquestionable.

3. Surfshark

Surfshark Firefox extension offers DNS leak protection.

More details about Surfshark:


  • Advanced privacy features
  • Bypasses geoblocks with ease
  • Affordable


  • No WebRTC leak protection

Surfshark Firefox extension stands out, thanks to its excellent array of features and high privacy levels. Like the NordVPN add-on, the Surfshark extension is an HTTPS-encrypted VPN that protects only traffic routed via your Firefox browser. The plugin offers an extensive array of security and privacy features that you may find handy, including a kill switch and DNS leak protection.

Surfshark has amassed a network of more than 3,200 servers, which is no small feat for a provider that only entered the virtual private network scene in 2018. Its servers are spread across over 65 countries, which gives you plenty of options to bypass geoblocking and access streaming services such as Netflix, Hulu, Amazon Prime Video and BBC iPlayer.

Comprehensive Suite of Advanced Tools

Beyond the standard features such as a strict no-logs policy, strong encryption and secure protocols, Surfshark’s add-on comes with a nice array of advanced privacy tools. For example, with CleanWeb — a reliable ad and tracker blocker — you’ll have fewer ads to put up with on Firefox. Plus, the Multihop feature allows you to connect via multiple servers to mask your online footprint.

Get started with the inexpensive yet reliable Firefox VPN extension.

Surfshark is a premium VPN app that comes at a rock-bottom price. For only $2.49 a month on the two-year plan, you get access to all the features and freedom to protect as many devices as you want. Read our Surfshark review to learn more. 

The Surfshark extension for Firefox packs a real punch in terms of functionality. Besides giving you a rich network of servers to spoof your location, it allows you to block ads, trackers and malware. However, Surfshark doesn’t offer WebRTC leak protection, and its servers aren’t as fast as our top two picks. For these reasons, it takes the third spot. 

4. Windscribe

Use Windscribe’s browser add-on on Firefox.

More details about Windscribe:


  • Free plan
  • Unlimited simultaneous connections
  • Advanced privacy features
  • Cheap build-a-plan option


  • Server speeds could be better
  • Free plan limits server options & has data limits

Windscribe is the best free VPN for Firefox. With servers in over 110 cities in 62 countries, the Windscribe extension gives you plenty of options to cloak your IP address to unblock georestricted content. However, you’ll have to subscribe to the Pro plan to access the entire server network, which is optimized for streaming. 

If all you want is to surf the web, the free plan offers 2GB of data, which is more than generous for roaming online. Windscribe raises the data cap to 10GB when you share your email address and 15GB when you tweet about the service. Binge-watchers or hardcore streamers can remove the data limits altogether by subscribing to its affordable premium plan.

Windscribe’s Advanced Privacy Features

Windscribe offers various advanced privacy tools that block attempts by hackers and snoopers to steal your personal information. For example, with location API spoofing, advertisers or sites that target you geographically can’t figure out your actual location.

Windscribe is the best free VPN for Firefox.

The Windscribe extension prevents WebRTC leaks by default and has a customizable ad- and malware-blocker to keep you safe online. It also gives you plenty of options to spoof your location, going as far as spoofing your timezone to prevent sites from identifying you as a VPN user. 

  • Up to 15 GB free with email confirmation and Tweet
  • 15GB
  • Unlimited

Windscribe’s free plan is quite reliable if all you want is to surf the web on Firefox. However, you can subscribe for $5.75 per month on the annual plan to take advantage of Windscribe’s full capability. Otherwise, you have a build-a-plan option where you can add a server location for just $1 per month, with a $3 minimum spend. Read our full Windscribe review to learn more.

5. Private Internet Access

PIA is one of the simplest VPN add-ons for Firefox.

More details about Private Internet Access:


  • Affordable & easy to use
  • Extensive server network
  • Fingerprinting protection


  • No access to advanced features
  • Privacy could be better

Private Internet Access (PIA) Firefox extension excels at unblocking restricted content. Like NordVPN or Surfshark, it’s an extension that redirects your traffic through an encrypted HTTPS server. The extension doesn’t achieve the same privacy levels as ExpressVPN or NordVPN, but it works magic when spoofing your location. Read our NordVPN vs PIA throwdown to learn more.

We like the PIA extension because it gives you an extensive network of servers to spoof your location and hide your actual IP address. Masking your IP address makes it impossible to link it to any of your online activity through IP detection. It also enables you to access blocked sites and streaming services such as Netflix, Hulu and Amazon Prime Video.

Get Fingerprinting Protection

PIA comes with the standard WebRTC leak protection and website URL allowlist. However, what makes this extension stand out is the fingerprint protection feature (read our guide to learn more about device fingerprinting).

With this feature enabled, it manipulates your browser API results, masking your device’s “fingerprint” — or unique attributes — such as timezone and language. In doing so, it prevents advertisers from attempting to identify you out of the crowd of internet users.

get pia vpn
Private Internet Access for Firefox is reliable.

PIA is a wallet-friendly VPN. Its three-year plan costs $2.19 per month, with two extra months at no cost, and it comes with a 30-day money-back guarantee. You can read our Private Internet Access review to learn more.

PIA Firefox extension covers the basics but offers little in the way of advanced features. It has an extensive network of servers that makes it best for accessing geoblocked or censored websites. However, it isn’t the best for defeating internet censorship or sailing the piratical waters. As a result, PIA is still a decent VPN but it earns only fifth place.

Honorable Mention: CyberGhost

CyberGhost VPN add-on excels at getting into restricted websites.

More details about CyberGhost:


  • Free
  • Easy to use
  • Solid privacy policy


  • The plugin is bare-bones

CyberGhost only earned honorable mention on our list, which is peculiar for a VPN service that ranks in the top five in most of our roundups. CyberGhost extension protects your traffic and secures public WiFi connections only in the Firefox browser. According to CyberGhost, the plugin is built on blockchain to guarantee optimal digital privacy.

However, CyberGhost Firefox extension offers a significantly thinned out suite of features. While it provides notable features — such as WebRTC leak protection —  it doesn’t come with a kill switch. 

The extension gives you access to only eight servers in four countries, and doesn’t offer specialized servers for streaming and torrenting. As a result, the plugin is useful only for online browsing or accessing restricted websites.

Final Thoughts

Hopefully by now you have found the best VPN browser extension for your needs. The next time you use Firefox to do your shopping, pay bills, game or stream, you won’t have to worry about your personal information getting exposed.

If you’re at a crossroads and don’t know which VPN service suits your needs, don’t fret. We recommend ExpressVPN as the best Firefox VPN because it ticks all the right boxes in terms of functionality, security and ease of use. It’s pricey, but it’s worth it.
