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. Before we get to the best Firefox VPNs, there are a few things to straighten out.

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.

Best Firefox VPN services

1. NordVPN

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 5,100+ servers in 60+ 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 2019, especially because it can work as a standalone, without the NordVPN app.

2. ExpressVPN

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 1,500+ 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.

3. Ivacy VPN

The winner of BestVPN.com’s Fastest VPN Award in 2019, IvacyVPN 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 IvacyVPN Firefox add-on helps you avoid ISP throttling and buffering, enabling highway-like speeds in 50+ countries.

While IvacyVPN doesn’t have a free trial, there’s a 7-day money-back guarantee, and 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 5 Eyes alliance member. It’s a standalone browser extension and can be used on 5 Windows or Mac devices simultaneously.

4. Windscribe VPN

Windscribe 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 550+ 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.

5. ZenMate

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.

6. Hide My IP VPN

We also wanted to add a completely free option in Hide My IP, the best proxy which also happens to have a Firefox add-on. It’s possible to stream Netflix with Hide My IP, but only the Russian and Romanian libraries.

Hide My IP also has a nagging screen asking you to log in each time you load a website, but that’s the price of a free Firefox VPN that aims to provide you with the most complete package, asking almost nothing in return.

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.

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.
