Firefox is easily one of the safest web browsers available today, but browser security isn’t everything. As such, it’s integral for every Firefox user to equip themselves with a virtual private network (VPN) to keep their data safe.
Using a Firefox browser extension vastly reduces the hassle of navigating your VPN app, and reduces data consumption by leaving apps other than your browser out of the VPN tunnel.
We would ordinarily recommend paid VPN providers, but if you’re set on using a free VPN, then this is the list for you.

3. Atlas VPN
Email, tickets, FAQ
- Military-grade encryption
- Automatic public wifi protection
- Unlimited bandwidth
- Easy-to-use apps
- Allows torrenting
- Few countries
- Apps lack features
Atlas VPN is the best Firefox VPN with a free version. No other free VPN gives you both unlimited bandwidth and P2P support. There’s also a nice premium version should you ever decide to upgrade.
This provider uses bank-grade encryption and a kill switch to protect you from accidental leaks. Atlas VPN does only minimal logging and doesn’t collect anything that could help trace you back. Most importantly, you don’t need to create an account to use the free version.
AtlasVPN offers two locations – the US, and the Netherlands. While the lack of servers in Asia might be a big deal for some, this service provides enough speed for safe torrenting worldwide. As expected, streaming with a free VPN is out of the question.
Currently, AtlasVPN doesn’t have any browser extensions, supporting Windows, macOS, Android, and iOS. The first in line is Chrome, though. Finally, the premium service costs $1.39/month.

ProtonVPN is a freemium service with a great free version. This Firefox VPN is mostly known for its security and unlimited bandwidth.
This service sports NASA-grade encryption, a robust kill switch, and solid leak protection. It uses IKEv2 and OpenVPN tunneling protocols, which provide good speeds for surfing the web or watching YouTube. However, torrenting and streaming are left for the premium plan subscribers.
Unlike Atlas VPN, ProtonVPN has servers in Japan, which is good news for those in Asia. Other options are the US and the Netherlands. The premium version expands your selection to 1300+ servers in 61.
ProtonVPN has apps for Windows, macOS, Linux, Android, iOS, Android TV, and Chromebook users. Unfortunately, no browser extensions are available at the time of writing this article. A free version allows you to use one device.

5. Hide Me VPN
- Great security features, decent speeds, barely any logs
- 10 GB/month bandwidth limit, only 5 locations, one device
Hide.me VPN is a popular free service that’s also among the best ones for Firefox. Just like Windscribe, it has a 10 GB monthly limit but offers twice as few locations and one device only.
Despite the aforementioned cons, Hide.me is still one of the best free VPNs currently available. It has military-grade encryption, a kill switch, and no logs. Additionally, this service offers WireGuard protocol, which greatly boosts performance.
While Hide.me VPN doesn’t unblock Netflix, it works great for torrenting. You will also find such features as a SOCKS5 proxy and split tunneling. Let’s not forget that you won’t see any ads as well.
In addition to Firefox, this provider offers a browser extension for Chrome. The premium version starts from $3.00/month. Should you decide to upgrade, you’ll get all 1900+ servers in 75+ countries, unlimited bandwidth, 10 simultaneous connections, and streaming support.
For a deeper investigation of Hide Me VPN, read our Hide Me VPN review.
- Military-grade encryption, kill switch, 25+ countries
- 500 MB/month bandwidth cap, no P2P or Netflix, logs more than minimum
Compared to the providers above, TunnelBear has a strict data cap of 500MB/month, which means it’s only really good for browsing. One can only comfort himself by remembering that P2P and Netflix are unsupported anyway. However, you can increase the limit by tweeting praise about the service (more details on their website).
While the data limit is disappointing, TunnelBear is otherwise a good free VPN for Firefox. It offers core security features, such as AES-256-bit encryption, a kill switch, and obfuscation (GhostBear). Things don’t look that well from the privacy standpoint – TunnelBear is logging more than the minimum and is also located in Canada, a Five Eyes country.
Speaking of countries, this service offers probably the best location selection (25+ countries). Connecting to a server that’s closer to your location often means better speeds and lower latency.
Those new to VPN industry will love TunnelBear’s fun and easy-to-use apps. There are also browser add-ons for Chrome and Opera. The full version costs $3.33/month and adds unlimited bandwidth, 1800+ servers in 34+ counties, and five devices per account.

7. Windscribe VPN
- Great security features, no-logs policy, unlimited devices
- 10 GB/month bandwidth allowance, based in Canada (Five Eyes)
Windscribe is one of the best free VPN for Firefox. This service offers all the security and privacy features that its premium version has. On top of that, a strict no-logs policy means your data isn’t collected. This also makes its Five Eyes jurisdiction less of a problem.
Another great thing about Windscribe is the unlimited number of devices. This means you can share your account with family and friends without ever running out of user slots.
Speaking of things that you can run out of, we have to mention the 10 GB/month bandwidth limit. Since Windscribe allows torrenting and usually unblocks Netflix, this can become an issue real quick.
Windscribe for Firefox gives you 10+ countries to choose from. That’s considered pretty generous, given that most free VPNs offer no more than five. It also supports a number of other browsers, such as Chrome, Opera, and Edge.
For just $1.00/month, you can get the full Windscribe version with no bandwidth limits, 480+ servers in 60+ countries, and reliable Netflix unblocking in the US, the UK, Canada, and Japan.

FAQ knowledge base, support tickets
- Unlimited bandwidth, kill switch, malware blocking
Security-conscious users will be thrilled to know that ZenMate uses the coveted, unbreakable AES-256-bit cipher and supports the OpenVPN and IKEv2 protocols. Other rarely found features among the free VPNs are malware and tracking protection.
Unfortunately, ZenMate is not a good choice if you care about privacy. It logs your IP address (though not your usage) and openly confesses that it will share it with the authorities if necessary.
However, it does seem to shoot itself in the foot with its poor connection speeds. That’s because ZenMate has a 2 MB/s speed cap. On the bright side, there’s no bandwidth limit, so you don’t have to worry about suddenly losing your online protection after a couple of days. But don’t expect to do any torrenting or streaming, which is available only to paid users.
The free version gives you 4 countries and one device per account. ZenMate also supports desktop-only Firefox. By spending $1.64/month, you will get 3400+ servers in 74+ countries, P2P, Netflix, and 24/7 customer support.

Difference between VPN browser extensions and apps
VPN browser extensions are a bit different from the typical VPN applications that most people use on a daily basis. For starters:
- Browser extensions usually have different features from the full application
- It’s technically not a full-fledged VPN, but a proxy
- It only secures the internet traffic coming from the browser
However, even though a browser extension isn’t as powerful as a dedicated VPN application, it still has its fair share of use cases.
How to install a free VPN for Firefox
When installing any kind of browser extension, it’s important to download the files from a reliable source. Browser extensions are notorious for hijacking personal data, browsing history, or installing malware. As such, choose your provider carefully and try to download the extension from official sources, for example, the VPN providers’ website.
Once you’ve picked a VPN, here’s how to fire up the VPN browser extension on Firefox:
- Choose a free VPN provider that supports Firefox. Our top choice is NordVPN, currently 72% off!
- Visit the Firefox add-ons page or the official website of your VPN service and download the extension for your browser
- Open the extension and log in with your credentials
- Connect to any server and enjoy secure browsing on Firefox!
Mozilla Firefox is an awesome privacy-respecting browser out of the box, but it can definitely be improved upon with some extras. For that, one of these VPNs will be a great addition. Just remember that companies can track you in a variety of ways, thus you’ll need more than just a VPN to anonymize yourself.
