Used by an estimated 360 million worldwide internet users, Mozilla Firefox is the fourth most popular web browser on the planet. It’s also thought to be one of the more secure options available, particularly if you use its private browsing mode. So what’s the point of getting a VPN add-on for Firefox? For starters, running a VPN extension on your browser when using the internet on insecure Wi-Fi networks can still leave you exposed. Connecting to a VPN will encrypt all of your traffic while you surf using Mozilla’s browser.

But we suspect most people use VPN add-ons for Firefox for their IP-shifting ability. That lets you effectively trick the browser into thinking you’re in an entirely different city or country — ideal if you’re looking to unblock a website or streaming service that is restricted at your location or you’re trying to watch live sport from an international broadcaster.

Keep reading to discover the best Firefox VPNs you can get right now before selecting a VPN deal to suit your budget.

Top VPN add-ons for Firefox

Whether you’re using NordVPN on Windows, as a mobile VPN, or on any of its other compatible devices, NordVPN is in the conversation as one of the best providers. And that’s no different when it comes to its VPN add-on for Firefox.

Getting started with the add-on is simplicity itself — you’ll benefit from NordVPN’s 6,000+ servers across 61 countries in virtually no time at all. Using it on Firefox will be one of the six simultaneous connections you’re limited to with this provider (a bit stingy compared to what most of the competition offers, with some even offering unlimited amounts).

If you’re a big streamer, you’ll be glad to know that NordVPN is particularly strong in this area, easily unblocking geographical restrictions placed on Disney Plus, Netflix, and Amazon Prime Video catalogs, as well as international-specific services like BBC iPlayer, Peacock, 7Plus, and Crave.

The add-on interface itself is ridiculously straightforward to operate. It doesn’t even feature the map-based interface that some people consider a turn-off on its desktop and smartphone clients.

The settings menu is somewhat stripped back from what it offers on those main apps, but you still get the option to toggle on auto-connect, a kill switch to make sure you’re not exposed if your connection fails, and split tunneling that lets you set domains and IPs that you want to be excluded from the VPN.

As one of the most security-conscious providers around, it also features a Threat Protection option that helps block ads and malicious websites you may encounter while surfing the web on Firefox.

The rolling monthly cost is slightly above the industry average. But things get more reasonable when you commit to two years, with deep discounts. The provider often carries reduced-price offers, too, so be sure to look out for those.

Priced from $2.49 per month, Surfshark undercuts most of the competition on pricing alone. You can use it simultaneously on as many devices as you wish, with 3,000 servers across 100 countries to connect to.

Pros & Cons

• Eye-catching pricing
• Unlimited device connections
• Loads of options

• Dashboard is relatively cluttered

If you like the sound of NordVPN, but the price tag is more than you were expecting to spend on your new VPN, then the great-value Surfshark might appeal more.

In addition to bargain-basement pricing on its two-year plan (starting at $2.49 per month at the time of writing), the provider also allows you to access its VPN on as many devices as you wish simultaneously without restriction. Great news if you were also hoping to share your user details with family or close friends.

With around 3,200 servers, Surfshark has a lower tally than NordVPN. However, they are spread across a greater number of countries — 100, at the current count. Surfshark also has a good reputation for streaming and boasts some of the fastest connection speeds on record, as tested by independent reviewers.

Generally speaking, Surfshark is recognized for its straightforward and beginner-friendly approach. On the contrary, we actually find the Firefox add-on just a little bit busier compared to others. It’s certainly not a disaster, but it does take a bit of getting used to.

It should also be noted that one of the reasons for that is the volume and variety of tools it offers. From creating an alternative online ID and private search function to blocking malware and checking for leaks, this is certainly a well-adorned extension.

And that’s before you even get to the settings menu, where you’ll find the likes of language select, bypass lists, pop-up blockers, auto-connect, threat protection, and more.

ExpressVPN’s Firefox extension is effectively a remote control for its desktop client. That means you have full access to its 3,000 servers across 105 countries with all the security settings and features offered by the full product.

Pros & Cons

• Servers in 105 countries
• Jam-packed with different settings
• Superb for streaming

• Need desktop client to operate
• Quite pricey

Let’s address the elephant in the room right away: the nature of ExpressVPN’s Firefox add-on is quite divisive. Rather than a standalone extension, it functions more like a browser-based remote control for the full desktop client that also needs to be downloaded.

For some users, this will be ideal, as it means you can easily control ExpressVPN while surfing in Firefox. But critics dislike the fact that it, therefore, impacts all of your internet traffic, not just what you’re doing on Firefox. Only you will know what side of the camp you’re on.

But if you like the idea of controlling the world’s best VPN from the basic interface in the top-right of your browser, ExpressVPN will suit you. For starters, it’s incredibly easy to set up and operate, with an invitingly large on/off button and a simple location list that lets you choose from 3,000+ servers in 105 countries.

The settings menu limits itself to auto-connect toggle, location spoofing, threat control, and HTTPS Everywhere, which automatically connects to a more secure HTTPS version of websites where available. For more in-depth settings, you’ll need to explore the desktop client itself.

ExpressVPN is one of the fastest services available and tops our list of the best VPNs for streaming as well. However, you should note that it’s also one of the more expensive options. Nevertheless, with a 30-day money-back guarantee, you can always give it a try risk-free to determine if it’s worth the investment.

US-based Private Internet Access (PIA) takes internet security very seriously. It combines a tried and tested no-logging policy with easy-to-use apps, 24/7 live chat support, and an astounding claimed 60,000+ servers in 91 countries.

Pros & Cons

• Watertight no-logging policy
• Well-priced
• Unlimited simultaneous connections

Private Internet Access (often abbreviated to PIA) claims — at the time of writing — to have 64,907 servers across 91 countries, including at least one in every US State. For context, that remarkable tally is over 60,000 more than ExpressVPN or Surfshark, and it’s a clear indication of some intent for a service that is among the world’s very best.

But those kinds of numbers tell only a tiny part of PIA’s story, and the US company is much more prone to crow about its open-sourced code and the way that every time a challenge comes via the courts to reveal information about its users, it has defeated them.

It means that if you’re living or traveling somewhere and are particularly conscious of keeping your identity hidden from prying eyes, then surfing the web with Firefox and the PIA extension enabled would be a reassuring option.

It’s generally decent for streaming, too, with most global Netflix catalogs and other streaming services unblocked. PIA can’t unlock Japanese Netflix; however, when we tried it out with Amazon Prime Video, we were unable to access shows that were exclusive to other countries.

Getting this VPN add-on for Firefox doesn’t have to mean spending a lot. Indeed, it usually has some of the best VPN deals around.

TunnelBear will take away any intimidation you may feel if you’ve never used a VPN before, thanks to its easy-to-use menus and Firefox add-on. Once installed, you’ll get a menu of 5,000 servers across 46+ countries, plus a free tier if you just want to try before you buy.

Pros & Cons

• Super simple to use
• You can try it for free
• 5,000+ servers

• Not many settings you can use
• Not good for Netflix streaming
• Others are faster

With its cartoony branding and ubiquitous bear-based wordplay, you may think TunnelBear doesn’t take internet security very seriously. However, this is a VPN provider with teeth — it just happens to be really easy for virtual private network newcomers, and it also features on our chart of the best VPN Chrome extensions.

TunnelBear has a network of 5,000 servers (above average) across almost 50 countries (below average). The Firefox add-on keeps things really simple: you can turn it on, change your server location, manage your account, and that’s about it. You won’t find any bells or whistles here, just a VPN proxy that will encrypt your browser traffic and spoof your IP.

That slightly limited feel extends to other areas as well. TunnelBear can’t compete with the likes of NordVPN and ExpressVPN when it comes to streaming. It generally struggles to unblock the US Netflix catalog from overseas, for example. You’re unlikely to see it featured on any lists of the fastest VPNs.

TunnelBear is reasonably priced and also offers a free option that limits usage to 2GB per month, but still provides access to all its global servers.

Mozilla has developed its own Mullvad-based VPN product that features 500 servers in 30+ countries and lets you connect up to five devices simultaneously. It functions on macOS, Android, iOS, Linux, and Windows, generally.

Pros & Cons

• Powered by Mullvad
• Multi-hop security
• Useful features

• Tricky to use within Firefox browser itself
• Limited server connections
• Not the fastest

It would be impossible to write an article about Firefox VPN add-ons without at least acknowledging the existence of Mozilla’s own version. It was finally released in 2020, following a long period of anticipation among Firefox devotees.

Mozilla has deferred to the experts to power its branded VPN. By partnering with Mullvad, it is underwritten by one of the most trusted players in the virtual private networks industry. That means you get the choice of Mullvad’s 500 servers in 30-odd countries (a meager selection compared to the rivals) and options such as “app exclusions” — another name for split tunneling.

Security-wise, it also offers ad, tracker, and malware blockers, and an easy-to-use multi-hop function that sends your internet traffic through two encrypted tunnels when enabled.

Unfortunately, Mullvad doesn’t tend to feature very highly in the speed testing charts when connection rates are put to the test by independent researchers. Streaming leaves a lot to be desired, too, with very little joy in unblocking the likes of Netflix, Disney+, or BBC iPlayer.

But perhaps the most frustrating and, frankly, odd quirk is that Mozilla VPN is a real pain to use in the Firefox browser itself. There’s no straightforward add-on like the rest of the services in this guide provides. Instead, you have to take the convoluted route of using the browser’s Multi-Account Containers. Unless you’re already well attuned to how these work, prepare for a head-scratching search through various online help guides. There’s no live chat customer support either, so there’s no instant access to assistance.

Windscribe’s free membership gives access to 20 server locations in 11 countries — not bad for a freebie. The default data limit of 2GB per month can be increased if you provide an email address or tweet about the provider.

Pros & Cons

• Delightfully simple to use
• Lots of functionality
• Extra data usage can be added

• Data limits start at 2GB per month
• Only 11 server country locations

If you remain unconvinced that a VPN add-on will make you more secure online than what Firefox offers but still like the idea of an extra layer of security or the ability to spoof your ID, you may want to consider getting a free VPN.

Look no further than Windscribe — a provider that has been around since the dawn of consumer VPN popularity, and offers a beautifully straightforward Firefox extension.

This VPN provides access to 20 city locations across 11 countries, which is more than most free VPNs can offer. The US, UK, Netherlands, Canada, Germany, Switzerland, and Hong Kong are all options, or you can let Windscribe choose by hitting the Autopilot option.

Once you sign up, you have up to 2GB per month to use, which increases to 10GB if you agree to share your email address with the company. You can also earn an extra 5GB by tweeting about Windscribe.

Even when compared to the premium services above, the free Windscribe add-on is generous in terms of the number of preferences and options you can play with. Auto-connect is turned on by default, together with its Ad Crusher, Tracker Eradictaor, and Malware Evader. Additionally, it offers extra settings to eliminate annoying cookie messages, prevent leaks, block web workers, and more.

Despite the price tag — or lack thereof — it’s also nice to know that Windscribe is decent at getting around geo-restrictions that prevent streaming what you wish when overseas on services like Netflix, Disney+, and BBC iPlayer.

Which VPN Firefox add-on should you install?

If you’re browsing the web on Firefox using a potentially insecure network, employing a VPN add-on for Firefox can be vitally important to ensure your security — even when using private browsing mode. Additionally, you gain the benefit of deceiving the browser into thinking you’re in a different location, which is useful for unblocking geographically restricted websites and streaming services.

NordVPN is the best VPN add-on for Firefox, offering fast speeds, 6,000+ servers, and the ability to unblock various streaming services. It’s also an absolute dream to use, with its Firefox extension in particular boasting a clean, friendly user interface.

ExpressVPN is a strong alternative, depending on what you really want from your Firefox extension. If you were thinking more along the lines of it effectively serving as a remote control for your main desktop VPN client, then ExpressVPN may be the better option.

You’ll benefit from having all of your internet traffic protected (not just what goes in and out of the Mozilla browser), as well as access to servers in 105 countries. Or if bargain hunting is more your concern, then Surfshark has the smarts to match NordVPN and ExpressVPN, just with a more wallet-pleasing price tag.

Although Mozilla has its own VPN, we’d recommend going for one of the others on this list instead. Mozilla VPN is easy enough to use and has a few handy features, but doesn’t compare favorably to the very best and is more expensive over a longer period.
