While Firefox is one of the top 3 most secure browsers, it still needs multiple plugins installed first to claim this spot. To begin with, it won’t be able to spoof and fully protect your IP address, not to mention unblocking geo-restricted content or climbing over China’s Great Firewall.

That’s why you need a Firefox VPN add-on that has it all in one package. And we’re here to help you pick the best one. So, let’s dive right in.

Best Firefox VPN services

1. NordVPN

Top VPN provider
Company location
Company location: Panama
Protocols: NordLynx, OpenVPN, IKEv2
Support: 24/7 live chat
  • Unbeatable in terms of security and privacy
  • SmartPlay to bypass the geo-blocks
  • Great for P2P
  • No router app

Unsurprisingly, one of the top-two VPNs overall ends up in the top Firefox VPN services list as well. Its encrypted Firefox VPN add-on gives you 5400+ servers in 59 countries, ensuring not only top-notch security but also great speeds. The light-weight NordVPN Firefox extension protects your browsing history, IP address, and forces HTTPS even if the site doesn’t have it. Additionally, their CyberSec feature blocks ads, trackers, and suspicious sites that might include malware or pose other threats.

On the downside, the Windows version of this add-on is still at version 0.9.21, having been updated almost a year ago. Nevertheless, it’s been downloaded nearly 40,000 times and has a 3.5/5 score from 289 reviews on Mozilla’s website.

We strongly believe that the NordVPN Firefox browser extension is one of the best options in 2020, especially because it can work as a standalone, without the NordVPN app.

2. Surfshark VPN

Top VPN provider
Company location
Company location: British Virgin Islands (BVI)
Protocols: OpenVPN and IKEv2
Support: 24/7 live chat
  • Great security features
  • Unlimited simultaneous connections
  • Smart DNS for smooth streaming experience
  • Weak self-help support section

Surfshark VPN created one of the best VPN extensions for Firefox. It provides solid security, spoofs your IP, unblocks Netflix and other streaming platforms and easily bypasses online censorship. Essentially, Surfshark VPN extension for Firefox offers the same stellar features as the VPN app.

Surfshark comes loaded with a powerful ad-blocker that will prove more than useful while browsing with Firefox. And with a Surfshark subscription allowing an unlimited number of simultaneous connections, you can protect your online activities on any device. And let’s not forget that with 1700+ servers in 60+ countries, Surfshark manages to offer impressive speeds pretty much anywhere on the planet.

Surfshark is one of the cheapest premium VPNs on the market, and we see no reason for you to wait for its prices to go up before you get it.

3. Ivacy VPN

Company location
Company location: Singapore
Protocols: OpenVPN, IKEv2, L2TP, PPTP
Support: 24/7 live chat
  • Excellent security
  • Great speeds
  • Works for streaming and torrenting
  • No kill switch for macOS & iOS

The winner of’s Fastest VPN Award in 2019, Ivacy VPN  also offers a nice Firefox extension for its users. It will help you unblock Netflix, Hulu, BBC iPlayer, and other streaming platforms while providing excellent security at the same time. The Ivacy VPN Firefox add-on helps you avoid ISP throttling and buffering, enabling highway-like speeds in 100+ countries.

Ivacy VPN offers a one-day free trial and a 30-day money-back guarantee. What’s more, the prices are almost too low for a premium service. On top of that, IvacyVPN accepts anonymous payments, such as cryptocurrencies. The only thing we don’t like is its location in Singapore, a partner of the Five Eyes alliance. It’s a standalone browser extension and can be used on 5 devices simultaneously.

4. PureVPN

Company location
Company location: Hong Kong
Protocols: OpenVPN, L2TP/IPSec, PPTP, SSTP, IKEv2
Support: 24/7 live chat
  • WebRTC blocking feature
  • Split tunneling
  • Temptingly low pricing
  • Weak kill switch

PureVPN’s Firefox add-on requires that you have an active account. This actually is a good thing, because free browser extensions that some providers decide to go with are nothing more than an advertisement of the actual service.

Like all add-ons, this one protects only your browser’s traffic. Therefore, you can use it to unblock streaming platforms and other websites, but it won’t do any good for torrenting. One great feature that PureVPN has implemented is WebRTC blocking. Without it, your browser is susceptible to leaks.

PureVPN for Firefox comes with a 31-day money-back guarantee and supports ten simultaneous connections. You’ll also be entitled to 24/7 live chat support.

5. Windscribe VPN

Company location
Company location: Canada
Protocols: OpenVPN, IKEv2
Support: Email
  • No identifying logs policy
  • Unlimited simultaneous connections
  • Ad and malware blocking
  • Complicated refund policy

Windscribe VPN is one of a few premium VPN services that have a great Firefox add-on and also a free version to try things out at your own pace. In fact, if you’re not into streaming and torrenting, 10 servers and 10 GB per month might just be enough. And should you decide to get a hold of all 480+ servers in 60+ countries to experience one of the fastest connection speeds, be ready for prices that would shock only Scrooge McDuck.

Windscribe’s Firefox VPN offers a double hop feature for extra security, as well as ad-blocking, timezone spoofing, user agent rotation to fight fingerprinting, and, last but not least, your very own Cookie Monster that del-eats them all to the last crumb when you close the browser tab. To avoid sounding like salesmen, we’ll point out that all of this comes at the cost of live chat support.

6. ZenMate

Company location
Company location: Germany
Protocols: L2TP/IPSec and IKEv2
Support: FAQ knowledge base, support tickets
  • Great variety of supported platforms
  • Easy to install and use
  • Works with Netflix US
  • Slow support

Free standalone browser extensions – that’s pretty much why the otherwise mediocre VPN service is often seen in the best VPN for Firefox lists across the web. Its Firefox add-on is ultra easy to use, unblocks Netflix, and allows you to connect to servers in 30+ locations worldwide. No wonder ZenMate has over 45 million users.

The drawbacks of using ZenMate is the lack of live chat support, and the existing one isn’t keen on answering you ASAP. Continuing on the subject of speed, don’t expect much in this department – there’s so much you can do with the overcrowding when having such vast userbase. To conclude, ZenMate is good if you’re sticking with its free version because you can get either ExpressVPN or NordVPN for a similar sum of money.

7. ExpressVPN

Company location
Company location: British Virgin Islands (BVI)
Protocols: OpenVPN, IKEv2, L2TP, PPTP
Support: 24/7 live chat
  • Excellent security
  • Great speeds
  • Awesome for streaming and torrenting
  • Very expensive

Omitting ExpressVPN from this list is unimaginable, even though at the moment of writing this review the extension was unavailable in Mozilla’s website. ExpressVPN offers one of the fastest, if not the fastest speeds, thanks to its vast network of 8.3+ servers in 90+ countries. The Firefox extension itself also works like a charm, while providing protection from WebRTC and DNS leaks, as well as other types of protection.

There are two caveats with ExpressVPN for Firefox, though. First, it requires the full app running to work, and second, it is still one of the highest-priced VPNs in the Solar System.

Caution about Hola VPN for Firefox

When it comes to Hola VPN, there are only three words you need –don’t use it! Even though Hola VPN is one of the most popular services because it’s free, that’s about it when speaking of its pros.

To begin with, it’s not even a VPN but a proxy, and one that certainly won’t end up on anyone’s best proxies list. Even if you don’t care about your privacy or anonymity, and you simply want to use Hola VPN for Firefox to access geo-restricted content, you’ll need the paid version to unblock Netflix.

And while Hola VPN can unblock torrenting, you should be ready to have your computer used as a “real” uploader of not only copyright-infringing but potentially also illegal content. That is because Hola VPN users share IPs and bandwidths among each other. And should something go wrong, good luck with contacting its support that has 175+ million users to attend to.

How we made this list

First, this list includes not only VPNs with a Firefox browser extension but also proxies, because in both cases it’s only browser traffic that’s being protected.

Second, not all the entrants below offer free versions because more often than not you have to pay for quality service in the online safety world. Besides that, those looking for the best free VPN for Firefox will get their own list soon.

Third, Firefox is an insanely unpopular mobile browser, which is why this article is first aimed at desktop users who will not be stunned to learn that a certain VPN has no Android or iOS browser extension of its own. In fact, most VPNs don’t have mobile browser extensions, and many desktop version add-ons are not supported.

Finally, there might be times when you want to protect your browser traffic only, leaving gaming, torrenting and other activities free. That’s when a browser extension becomes handy, and if your VPN provider doesn’t have one, you’re on your own to find a third-party solution for Firefox.

About Mozilla Firefox

Firefox is the third most popular browser in the world. Started back in the early 2000s by the Mozilla Foundation as an alternative to the infamous Internet Explorer, this free and open-source browser has slowly but steadily climbed the ladders of popularity for a decade, peaking at 35%.

It is then when the free and closed-source browser from the search giant Google put its claws on the rails, starting to methodically shake the poor Firefox off.

It’s the turn of the decade again, and we find Firefox shaken, but not stirred. Hanging on below 5% at a near-extinct level, just like the red panda in the browser’s logo, Firefox is still a firm #2 among desktop users. What’s more, it’s the most popular browser in some countries, such as Cuba or Eritrea.

But Firefox has not forsaken the mobile market which has truly been its evil poacher in the last ten years. With the rebranded Firefox for Android, Firefox and iOS, and the security-oriented Firefox Focus, Mozilla rises again to fight the likes of mCent and KaiOS on its path to gaining back the “7 inches or less” domain.

    ExpressVPN is one of the best, undeniably! If you are still thinking which VPN to avail for yourself, please get ExpressVPN. It works just fine without any issues for me so far

  2. CaptainRogers

    Windscribe all the way! I’m a big fan of their free service to suggest to people new to VPNs. Most people who just need to protect themselves aren’t looking for heavy duty torrenting and Netflix unblocking, so it’s a good one to ease them in with.

    After that, when you’re ready for a paid one, I’d go with ExpressVPN. Popular because it works!

  3. Altair

    I would go with the NordVPN extension because they have the most servers and that makes things easier and increases the chance you have multiple servers near you so your speed can be high. I also trust them above all others when it comes to my privacy and online security.

    NordVPN wins in all categories. Android, Windows, iOS, etc. It is definitely the best VPN service out there! I love it, and it never lets me down.
