Best VPNs For Mozilla Firefox in 2021

Just behind Google Chrome, Mozilla Firefox is the second-most-popular internet browser, with over 250 million users worldwide. The browser has a decent reputation when it comes to blocking smaller website trackers, but if you want to fully secure your internet connection and browse the net anonymously, a VPN is the best tool to keep you safe online. 

Written By: Adam Dagan Cyber security & Privacy expert

A quality VPN for Firefox will keep your data secure by blocking malware, allow you to stream the latest films and TV shows that aren’t available in your country, and prevent cybercrime such as hacking and ID fraud. You don’t need to run a native VPN app to secure your Firefox connection, either. Many of the largest providers offer proxy extensions, lightweight versions of their VPN software, that can run directly from your browser. 

There are hundreds of VPNs out there, and we know how difficult it can be to find one that suits your specific requirements. That’s why our researchers have spent the last few weeks testing every provider to drop up a list of the ten best VPNs for Firefox in 2021. Let’s start with the top five.

Short on time? Here are the Top 5 Firefox VPN Picks Quick Overview

  • Excellent speeds - no slow down experience
  • Zero latency – smooth gaming experience
  • Ease of use - set up in a couple of minutes
  • No-logs policy - Your data is 100% untraceable.

What is a VPN and Why do you need a VPN for Firefox?

Every time you connect to the internet, all of your browsing history – including the websites you visit, where you’ve clicked, and how long you spend on a page – is recorded by your Internet Service Provider (ISP), Google, and other websites. A Virtual Private Network (VPN) is a tool that makes your IP address and you completely anonymous online. It does this by routing your connection through an encrypted tunnel to a private server. 

VPN’s have servers located all over the world, which means you can also use them to unblock geo-blocked content that isn’t usually available in your country. For example, if you live in the United States and want to stream BBC iPlayer – an app which is usually only available to people living in the UK – just use your VPN to connect to a UK server and you’ll be able to geospoof your location.

Speed and Security are Key Factors When Choosing a VPN for Firefox

If a browser extension slows your connection down, it’s no good for you, and that applies to VPNs too. While it’s not unusual to notice a slight dip in your connection speed when you’re using one, this decrease in speed shouldn’t be noticeable, and it should certainly never affect your device’s performance. Hundreds of VPNs’ll claim to offer ‘lightning-fast speeds,’ but only a small handful can live up to their promise. One of the benefits of using a proxy extension like a Firefox VPN add-on is they don’t use as much CPU as a native VPN app, so your internet connection will be just as fast, if not faster, than usual. 

With all of the risks out there on the internet, security is just as important as ultra-fast connection speeds. A VPN encrypts your information to protect you against hackers, but additional security features will also help keep you safe online. If you live in a country with strict internet censorship, it’s paramount that your provider operates with strong privacy policies too.

Which VPN is the Fastest and Most Secure for Firefox? 

We’ve tested every VPN out there and found that when it comes to speed and security, ExpressVPN is the best. Its Firefox add-on is compatible with Windows, Mac, and Linux devices, and protects your web activity with military-grade encryption. Optimized servers deliver the fastest speeds straight from your browser. 

How to Set Up a VPN on Firefox 

Connecting your VPN to Firefox couldn’t be any simpler. Simply follow these steps. 

Setting up a VPN on your browser is easy, regardless of which one you’re using. If you just want to use the Firefox add-on to protect your browser, follow the steps below.

  1. Sign up with one of the providers from our top ten list below and create an account
  2. Download and install the Firefox extension from your chosen provider’s website
  3. Open the extension in Firefox and log in
  4. Connect to a server and your internet traffic is now fully encrypted!

If you want to protect all of the traffic coming from your device (an add-on will only encrypt the information you’re transferring through your browser), you’ll need to download a native VPN app for the device you’re using. 

You can also install the VPN software onto your router so any device connected to it is automatically protected. Most providers sell pre-flashed routers with everything you need already pre-installed.

Does Mozilla Firefox Come With VPNs Built In? 

Firefox doesn’t have a built-in VPN, but in November 2019, it launched its own VPN for the browser. It costs $4.99 per month and is currently only available in six countries. $4.99 may sound cheap, but there are plenty of other VPNs, such as Surfshark, with subscriptions that include far more security features than the Firefox VPN for half the price. 

We’re also slightly concerned about Firefox’s privacy policy, which states that while it doesn’t log, track, or share your network activity, it does ‘collect the most minimal data required to keep the VPN healthy and operational.’ That’s pretty ambiguous if you ask us, and we can guarantee your privacy would be better protected using one of the VPN providers on this list, many of which have over a decade’s worth of experience protecting their users’ information. 

What to Consider When Choosing a VPN for Firefox 

With so many VPN providers to choose from, knowing what features to look out for will help you make the best choice. 

Compatibility with Firefox 

With Firefox, it makes sense to choose a provider that offers a VPN proxy as a Firefox extension. If you’re not running any other software that needs encrypting outside of your browser, these are useful little tools that’ll run smoothly to hide your online activity from your ISP. While there are lots of VPNs that offer browser extensions, not all of them support Firefox, so make sure you’ve checked before taking out a subscription. 

Quality Security Features 

Military-grade (AES-256 bit) encryption will help secure your connection, but other security features, such as double VPN protection, a kill switch, and DNS/IPv6 and WebRTC leak protection are equally as important to keep your online activity hidden. For Firefox, you should also prioritize VPN providers that offer their own ad-blocking and malware tracking software, especially if you’re not using anti-virus software already. And for all you Mac users: it’s a myth that your devices are strong enough to fight malware on their own without such software! 

Lightning Fast Connections 

If you’re planning on accessing streaming apps through your browser, spending hours on YouTube, or playing online video games, you don’t want your VPN to slow down your connection. Many VPNs offer servers that have been optimized for a specific reason, such as online gaming or streaming, and these will always offer faster speeds than non-optimized servers. 

Large Server Network 

One of the reasons VPNs are so popular is because they’re the easiest way to access region-locked content. Unfortunately, not all VPNs are as effective at unblocking websites and streaming apps. All of the providers on this list have been fully tested to unblock the biggest apps out there, and this is largely down to the size and quality of their network. Generally speaking, the more servers you can connect to the better, because if any of them ever get flagged by a website’s VPN detection software, you can just switch to another server.

Top Ten VPN Services for Firefox - Full Overview

Written By: Adam Dagan Cyber security & Privacy expert

1. ExpressVPN

Not only does ExpressVPN deliver the fastest connection speeds with bespoke security features, it’s also got the most powerful VPN extension for Firefox. The Firefox add-on is simple to use and provides instant VPN connection with just one click. With WebRTC leak protection and location spoofing, you can use the extension to prevent websites from learning your location and unblock region-locked content from anywhere in the world.

Our researchers used it to successfully unblock Netflix, Amazon Prime Video, and BBC iPlayer from servers in Japan, UK, and France, and ExpressVPN’s TrustedServer technology is independently audited to offer the highest levels of privacy. It operates with a strict no-logging policy too, so you won’t have to worry about your personal information being shared with third parties. With support for Mac, iOS, and Windows desktops, you shouldn’t have any issues hitting the ground running once you’ve taken out a subscription.

NordVPN’s lightweight Firefox extension lets you stay safe while you’re using the browser without slowing down your connection.

It’s simple to use, and Nord’s Auto Connect feature will always match you with servers offering the lowest ping and latency.

An added bonus is you’ll be able to access region-locked content that’s not available in your country, and if you’re running Steam through your browser, you’ll be able to access gaming discounts from all over the world. NordVPN is our top pick for a Firefox browser if you’re mainly using the internet for entertainment purposes.

3. Hotspot Shield

It’s taken it a while to catch up with other providers, but Hotspot Shield finally added a Firefox extension in September, and it offers lightning-fast speeds thanks to its proprietary Hydra protocol. The proxy app for Firefox means you don’t need to install the VPN and run it as a separate program and it’s free to download if you’ve taken out a premium subscription with Hotspot Shield – which is essential if you want to experience its full suite of security features. The free plan is very basic with restricted bandwidth, so we’d recommend avoiding it. 

You won’t be able to access all of Hotspot Shield’s VPN locations using the Firefox extension, but you can still gain a connection to locations such as the UK that are needed to unblock ITV Player and BBC iPlayer. It’s one of the easiest VPNs to use, and security features such as DNS/IPv6 and WebRTC leak protection will prevent your ISP and anyone else from discovering your true location or IP address while you’re connected.

Not Recommended for... If you want to access all of Hotspot Shield’s servers, you’ll need to run the full native app.

Bottom Line 

Hotspot Shield’s patented Hydra protocol and powerful military-grade encryption have made it the first line of defense for many internet users. With impressive speeds, apps for all platforms, and excellent customer support, Hotspot Shield is a solid VPN choice for Firefox.

4. Surfshark

Surfshark operates with a trusted no-logging policy to guarantee your privacy, and it’ll bite chunks out of anyone geo-blocked website it encounters while you’re surfing the net. All it takes is two clicks to set up the Surfshark Firefox extension – just click on the VPN to open it and then connect to one of over 1700 optimized servers to hide your IP address. Surfshark provides its own DNS on all of its servers, so you’ll never have to worry about any troublesome leaks either. 

The biggest selling point is the subscription prices, which start from just $1.99 per month. That’s incredible value for money, especially when you consider all of its subscriptions include CleanWeb, a bespoke security feature that blocks ads, trackers, malware, and phishing attempts made on your Firefox browser. And while some providers only support connections for up to five or six devices, a Surfshark subscription lets you protect every single device in your home with unlimited simultaneous connections.

Bottom Line 

If you’re looking for a cheap Mozilla VPN, you won’t find another one that offers better value for money than Surfshark. Not only is this digital shark super fast, it’s also got some of the best security features we’ve seen. Take out a subscription and you’ll be able to protect every single internet-connected device in your home with military-grade encryption for just $1.99 per month.

CyberGhost’s VPN Firefox extension lets you float straight through geo-restrictions, censorship, and all-round digital limitations by encrypting your internet traffic to make your online activity completely anonymous. As it’s based in Romania, it doesn’t fall within the five-eyes, nine-eyes, or 14-eyes jurisdictions, and operates with one of the strictest privacy policies we’ve seen, meaning you can trust CyberGhost with your personal information.

CyberGhost also has one of the largest networks out there, comprising over 6000 servers that have been optimized for online gaming, streaming, and P2P activity, making it a favorite amongst torrenters. That means it’ll sneak past the geoblocks that are used by some of the world’s biggest streaming apps such as Netflix and Amazon Prime Video too. With unlimited bandwidth, you can say goodbye to data caps and stream until your heart’s content on any of your devices.

The extension is easy to navigate and lets you connect to IPVanish’s full network of over 1500 servers. Speeds weren’t the fastest our researchers have experienced, but the connections were consistently strong, supporting Ultra HD streaming.

9. TunnelBear VPN

Though TunnelBear offers a free plan, stay clear of it. It only offers base-line protection and isn’t strong enough to provide the security features you need to keep you safe on Firefox. Besides, $3.33 per month for a VPN subscription is fantastic value, especially when TunnelBear’s VPN includes unlimited bandwidth, AES 256-bit encryption, a kill switch, DNS/IPv6 leak protection, and unlimited server switching. As it operates with a strict no-logging policy, which is also independently audited by a third-party cybersecurity company, you won’t have to worry about your personal information being bear-handled. 

Sure, its server network isn’t the same size as larger providers such as CyberGhost or NordVPN, and that does mean you’ll only be able to unblock Netflix and Amazon Prime Video in the US, but if you’re looking for a user-friendly Firefox extension that runs smoothly in the background of your desktop, this is it. No complicated configurations required, TunnelBear is a simple VPN that delivers all of the basic features you need to keep you safe when you’re browsing.

10. HMA! VPN

Formerly known as Hide My Ass! VPN, this UK-based provider operates a network of over 1100 servers in 190+ countries, making it a powerful tool for unblocking region-locked websites and streaming apps straight from your Firefox browser. The Firefox app works by encrypting your data, preventing it from being accessed by third parties and hackers. There’s a built-in ad-blocker and malware scanner to keep you safe; plus, additional features such as the Tab Killer and Auto Disguise are perfect for hiding your internet traffic from your ISP.

It’s simple to use, and you can access all of HMA! VPN’s servers from the Firefox extension alone. Speeds were consistently strong, although our researchers did report large dips when they were connected in Japan. If you’re looking for a lightweight proxy extension that won’t drain your CPU in the same way as native apps, this UK VPN is a decent choice.

Additional Insights and FAQs

Are VPNs Legal to Use on Firefox?

Firefox doesn’t have any specific rules surrounding VPNs and all of the providers we’ve featured in this list are recognized by the browser as being trusted apps. However, VPN rules vary all around the world, so if you’re traveling to a country with stricter internet censorship such as Turkey or the UAE, make sure you’ve looked at the rules surrounding VPNs so you don’t get into trouble for using the tool.

Will These VPNs Run on Different Browsers?

All of the VPNs we’ve featured in this list also have browser extensions for Google Chrome, but smaller browsers, such as Opera, may not be supported. And if you’re still using Internet Explorer in 2020 (why?!), it’s worth noting that third-party extensions are no longer supported, so you’ll need to protect your connection using a native VPN app.

Mozilla Firefox Extensions vs Native Apps

VPN browser extensions are designed to be lightweight versions of native VPN apps, and as such, they don’t always include the same security features. While a Firefox Extension is a quick and easy way to encrypt your internet traffic and mask your IP address, it isn’t able to mask other internet activity coming from your devices, such as any torrenting software you’re running. For complete protection, we’d always advise using a VPN’s native app, and never choose free VPN extensions without taking out the paid-for subscription first.

Can People Detect My VPN While Using Mozilla Firefox?

Once you’re using the VPN, your ISP and the websites you’re visiting won’t be able to track your information as you’re completely anonymous. However, if you’re visiting blocked websites or unblocking region-locked apps using the tool and it suddenly goes down, your ISP might be able to track what you’re doing. This is why you should always use VPNs with a kill switch, as they automatically cut your internet if your VPN connection drops out.

Can You Trust Your VPN Service?

As you’re relying on your VPN to anonymize your internet traffic while handing them your personal information, it’s important you can trust them. Thankfully, there’s an easy way to do this. Just check to see if your provider operates with a no-logging policy. This makes clear whether or not it logs and stores any data that can be traced back to you. You should also check their location and whether or not they fall within the five-eyes, nine-eyes or 14-eyes jurisdictions. It doesn’t hurt to read through your provider’s privacy policy too, as it’ll help you see how transparent they are about how they process your information.

Can You Use Free VPNs With Mozilla Firefox?

You’ll notice that a lot of VPNs say their browser extensions are ‘free’, but you shouldn’t use them unless you’ve taken out a premium subscription, as free extensions don’t include the necessary security features to keep you safe online.
There are also plenty of free VPN services out there masquerading as legitimate providers. Any VPN that solely offers a free service is not to be trusted. Since they don’t make revenue off user subscriptions, they resort to making money from selling their users’ personal information. And we all know how valuable data is and how annoying it can be when your personal information falls into the hands of marketing companies, or worse, criminals!
A quality VPN doesn’t have to break the bank, so if you’re seriously concerned about spending too much on a provider, just take out a subscription with a cheaper brand such as Surfshark.

Does Your Firefox Browser Not Work With Your VPN? Try These Methods

Should your VPN software stop working with Firefox, the easiest fix is to uninstall it and check both your VPN and your browser is updated to the latest version. That should solve the vast majority of issues, as the most common errors are usually related to compatibility flaws and out-of-date software.
Every provider is different, and there are lots of different devices and platforms out there, so consult your VPN directly for specific troubleshooting issues.

Summary

Firefox is a decent browser and if you fancy accessing blocked websites or discounts, using a Firefox VPN extension can help you save loads of money on your favorite digital purchases such as movies and video games while hiding your online activity from your ISP. For top-quality performance, just make sure you’ve chosen one of the providers on this list, as they’ve been rigorously tested by our VPN researchers in locations all over the world.
