Best Firefox VPN Extensions 2024: Free & Premium Add-Ons

Despite being a privacy-focused browser, Firefox’s traffic isn’t encrypted, meaning surveillance agencies and third parties can see what you do. So, pairing Firefox with a VPN is essential to ensure airtight safety and privacy during online activities.

After extensively testing more than 30 services, I’ve picked the top VPNs that work reliably with Firefox via browser extensions or native apps. The apps below use unbreakable AES 256-bit encryption and other safety features for protection. Plus, they maintain fast connection speeds that let you enjoy lag-free browsing and streaming.

ExpressVPN is the best overall choice for Firefox. Its impenetrable security, intuitive Firefox extension, and superfast speeds make it stand out. Plus, the 30-day money-back guarantee lets you get a full refund if you’re unsatisfied with it. I got my refund in just 3 days.

Key Features:

ExpressVPN is the best Firefox VPN, delivering fast speeds without compromising security. It has a reliable Firefox extension with many useful safety features, such as WebRTC leak protection and location spoofing — these stop websites from detecting your true location when you’re connected.

I never experienced an IP address leak while testing ExpressVPN, so my real IP and DNS information was never visible to a third party. You’ll also get the following security features:

• AES 256-bit encryption — makes your personal information unreadable to hackers.
• No-logs policy — ensures none of your browsing activity is stored or shared.
• Kill switch — instantly disconnects your internet to keep you anonymous if the VPN connection drops.
• TrustedServer technology — RAM-based servers have no hard drive to store user information and wipe all data whenever they reboot.
• HTTPS Everywhere — connects you to a website’s more secure HTTPS version whenever available.
• Threat Manager — blocks trackers and malicious websites.

ExpressVPN also has a massive network of 3,000+ servers in 105 countries. This ensures you can always find a nearby location and won’t have to deal with overcrowded servers causing delays and lag.

There were minimal slowdowns during my speed tests. The connection speeds were similar to my baseline speeds on most servers. Even when connected to long-distance servers, I only noticed a 10% drop in download speed (330Mbps to 300Mbps). With these fast speeds, you can enjoy lag-free browsing and streaming.

Installing ExpressVPN on Firefox is easy. You can either search for it directly on the official Firefox add-ons website or log into ExpressVPN’s web portal to get the Firefox extension link. ExpressVPN is also available for other platforms like Windows, Android, iOS, macOS, and many others.

You need ExpressVPN’s desktop app for the Firefox extension to work. Ensure you have a subscription and are logged into the app before you install it, as you need to authenticate it via your desktop to start. Once you’ve set it up, the extension performs just as well as native apps.

It costs a little more than other premium VPNs, but ExpressVPN is worth its price. Plus, you can get it for as low as $6.67/month with the 1-year + 3 months plan (a 49% discount). There’s also a generous 30-day money-back guarantee that lets you get a full refund if you’re unsatisfied with the app’s performance. I got my money back in just 3 days.

2. CyberGhost — Comes With a Free Firefox Proxy That Hides Your IP and Maintains Fast Connection Speeds

Key Features:

CyberGhost offers a free Firefox proxy that lets you hide your IP address online. It has 4 locations you can connect to. Plus, there’s no data limit, meaning you can use it as much as you want without restrictions. Note that streaming performance isn’t as good in the free proxy, so you’ll need the full app if you want to watch shows and movies.

While the free Firefox proxy is impressive, CyberGhost’s premium app is even better. It gives you access to the VPN’s impressive network of 11,800+ servers across 100 countries, so you’ll be able to connect to a local server wherever you are for the best performance.

During tests, CyberGhost gave me fast connection speeds on local servers. I only experienced a 15% drop on nearby servers, taking my speeds from 330Mbps to 285Mbps. My average download speed on long-distance servers was 270Mbps, a 20% drop. You may get slower speeds on the free extension, which can get crowded due to the limited server selection.

CyberGhost offers 3 VPN protocols: OpenVPN, IKEv2, and WireGuard. Both OpenVPN and WireGuard are excellent for maintaining security, and the app also offers the following to improve protection:

• AES 256-bit encryption — secures your traffic, so no one can spy on what you do.
• No-logs policy — doesn’t store logs of your browsing or other online activity.
• NoSpy servers — internally-operated CyberGhost servers that guarantee anonymity.
• Kill switch — disconnects your internet to keep you anonymous if the VPN connection drops.
• RAM-based servers — all servers are RAM-based, meaning they lose all their data on reboot.
• Smart Rules — connects the VPN automatically when certain conditions are met to ensure safety.

Besides the Firefox proxy,CyberGhost has native apps for Windows, macOS, iOS, Android, and more. Also, you can set it up on your router to secure all the devices on your network.

CyberGhost keeps some data like your email, payment information, and cookie preferences when you use its website. This data isn’t ever linked to your online activity, but this is still worth keeping in mind.

While the Firefox extension is free, you can get CyberGhost premium for as low as $2.03/month with a 84% discount if you choose its 2-year + 4 months plan. Plus, the generous 45-day money-back guarantee gives you lots of time to test the app risk-free and see if it’s right for you.

3. Private Internet Access (PIA) — Includes the MACE Feature in Its Firefox Extension to Block Ads and Trackers

Key Features:

Private Internet Access (PIA) provides its helpful MACE feature in the Firefox extension. MACE blocks ads, trackers, and malicious sites at the DNS level, ensuring you won’t be bothered by annoying ads or accidentally open sites loaded with malware.

Plus, PIA includes various other useful features that help you stay safe online.

• AES 256-bit encryption — prevents attackers from spying on your online activity.
• No-logs policy — doesn’t store logs of your online activity.
• Leak protection — keeps your IP address and other identifying information from leaking online.
• HTTPS enforcement — makes you always visit the secure version of a website.
• RAM-only servers — ensures PIA can’t log your activity, as all the data is wiped whenever a server is restarted.
• Kill switch — disconnects your internet if the VPN disconnects to keep you anonymous.

It has a large network of 35,000+ servers in 91 countries, and PIA’s servers performed well in my tests. Nearby servers had negligible speed drops, but my connection speed fell from 330Mbps to 142Mbps during tests on long-distance servers — a significant reduction that can affect browsing and streaming depending on your baseline speed.

PIA allows unlimited devices to connect simultaneously, making it perfect for securing connections on all your devices. Aside from Firefox, PIA is available on Mac OS, Android, iOS, and even Linux. It’s very versatile, and you can use the PIA extension without installing its desktop app.

There’s no free extension, but pricing for PIA starts at just $2.03/month, thanks to a 83% discount that you get with the 2-year + 4 months plan. If you need a short-term subscription, PIA is one of the top monthly VPNs available. Whichever plan you choose, you can try PIA without risk, as it’s backed by a 30-day money-back guarantee.

4. NordVPN — Offers a Feature-Packed Firefox Extension With Various Useful Tools

Key Features:

NordVPN has one of the most feature-rich Firefox extensions I’ve seen. It works without the app, and its Threat Protection Lite feature is especially impressive, as it secures against unsafe sites, trackers, and ads. Plus, you get the following features for improved safety:

• AES 256-bit encryption — secures your browsing activity against prying eyes.
• No-logs policy — ensures none of your browsing activity is stored.
• Leak protection — stops your IP and other identifying information from leaking.
• Double VPN — routes your traffic through multiple servers for added protection.
• Privacy-friendly jurisdiction — operates from Panama, outside the 5/9/14 Eyes alliance’s network.

The extension gives you access to all of NordVPN’s 6,300+ servers, and its streaming performance is as good as the native app. NordVPN works with Netflix, Prime Video, and other popular streaming platforms, so my team and I had no trouble watching streaming libraries in our home regions.

Connection speeds on NordVPN servers were decent in my tests — only dropping from 330Mbps to 290Mbps on nearby servers. However, you might notice a more significant drop if you use Double VPN, as it redirects traffic through multiple servers.

The extension isn’t free, but the cheapest 2-year + 3 months NordVPN plan costs just $3.09/month, as you get a 69% discount with it. Also, the 30-day money-back guarantee lets you try NordVPN without risk.

5. Surfshark — Provides Malware and Phishing Protection With Its Firefox Extension

📍Servers	3,200+

💰Refund	30 days
📝Keep logs	No

Key Features:

Surfshark provides an independent Firefox extension that doesn’t need the desktop app and has malware protection features. It stops you from opening potentially unsafe websites and also informs you if a website is known to contain phishing scams. When I tested it, it reliably kept me from opening dangerous websites that may infect my system or compromise my data.

Other security features you get with Surfshark’s Firefox extension include the following:

• AES 256-bit encryption — stops third parties from spying on your browsing activity.
• CleanWeb — blocks annoying ads and trackers online.
• Alternative ID — provides an alternative persona and email alias to use on websites.
• Camouflage mode — disguises your traffic as a regular connection to ensure anti-VPN firewalls can’t block you.
• Bypasser — lets you customize which apps use the VPN tunnel and which apps use your regular connection.

Surfshark also maintains fast connection speeds on most of its 3,200+ servers. My speeds only dropped to 300Mbps from 333Mbps (10%) on nearby servers, but they dropped to 230Mbps (30%) on long-distance servers. Nonetheless, my connection remained fast enough for smooth torrenting, gaming, and UHD streaming while using Surfshark.

My only issue with this VPN is that Surfshark is based in the Netherlands, a member of the 9 Eyes alliance. Thankfully, a no-logs policy ensures your activity isn’t stored on its servers. Also, Surfshark’s website has a warrant canary to inform you if the company gets subpoenaed by the government or law enforcement.

The extension isn’t free, but you can get Surfshark for $2.29/month with the 2-year + 2 months plan that offers a 85% discount. It’s a reasonable price for the VPN, and there’s also a 30-day money-back guarantee that lets you try Surfshark without risk.

6. hide.me — Delivers a Free Firefox Proxy With 3 Location Options

📍Servers	2,400

📝Keep logs	No

Key Features:

hide.me has a free Firefox proxy that works without the main app. The free proxy lets you connect to up to 3 locations (Germany, Switzerland, and the US) — you’ll need a premium hide.me subscription to access its full network of 2,400+ worldwide servers.

hide.me includes WebRTC leak protection to ensure your IP isn’t leaked online. It also has the following to ensure airtight safety:

• AES 256-bit encryption — protects your online activity, so no one can see what you’re doing.
• No-logs policy — never keeps logs of your activity on its servers.
• QUIC blocking — stops QUIC-enabled sites from downloading harmful content onto your system.

While its download speeds are decent, I noticed that hide.me struggles with upload speeds. On most servers, my download speed didn’t drop more than 30% (330Mbps to 230Mbps), but the upload speeds slowed down to 10Mbps (from 330Mbps) sometimes, making Zoom calls and other upload-reliant activities much laggier.

Besides the free extension, you can subscribe to hide.me premium for as low as $2.69/month if you choose the 2-year + 2 months plan, as it has a 73% discount. Whichever plan you choose, there’s 30-day money-back guarantee, meaning you can try hide.me without risk to see if it suits you.

7. TunnelBear VPN — Provides Generous Data Allowance in Its Free Firefox Extension

Key Features:

TunnelBear’s free Firefox extension offers 2000 MB/month of data, which is enough for day-to-day browsing. I also like that it’s a simple and easy-to-use extension that can work without needing to download a VPN app.

During tests, TunnelBear’s connection speeds remained reasonably fast. I experienced a 20% drop (330Mbps to 270Mbps) compared to baseline speeds on nearby servers, which increased to 50% (330Mbps to 166Mbps) when I connected to the long-distance server in the US.

TunnelBear maintains reliable security via the following features:

• AES 256-bit encryption — defends your connection with military-grade encryption to prevent others from spying on your traffic.
• No-logs policy — doesn’t keep logs of your browsing activity while using the VPN.

You can’t connect to all of TunnelBear’s server locations if you use the free extension. So, you must get TunnelBear’s premium plan if you want access to its full network of 5,000+ worldwide servers.

If you want to remove server and data restrictions, the 2-year plan lets you get TunnelBear premium for as low as $4.17/month with the 58% discount. There’s no money-back guarantee, but TunnelBear processes refunds on a case-by-case basis, so you still might get one if you have a good reason.
