Best VPNs For Mozilla Firefox in 2021

Not only does ExpressVPN deliver the fastest connection speeds with bespoke security features, it’s also got the most powerful VPN extension for Firefox. The Firefox add-on is simple to use and provides instant VPN connection with just one click. With WebRTC leak protection and location spoofing, you can use the extension to prevent websites from learning your location and unblock region-locked content from anywhere in the world.

Our researchers used it to successfully unblock Netflix, Amazon Prime Video, and BBC iPlayer from servers in Japan, UK, and France, and ExpressVPN’s TrustedServer technology is independently audited to offer the highest levels of privacy. It operates with a strict no-logging policy too, so you won’t have to worry about your personal information being shared with third parties. With support for Mac, iOS, and Windows desktops, you shouldn’t have any issues hitting the ground running once you’ve taken out a subscription.

NordVPN’s lightweight Firefox extension lets you stay safe while you’re using the browser without slowing down your connection. With unlimited bandwidth and data, you won’t have to worry about your ISP throttling your bandwidth during peak times, and a massive network comprising over 5400 high-powered servers provides some of the fastest speeds available for streaming apps such as Netflix and Amazon Prime Video. 

Your internet traffic is fully encrypted when you’ve got the Firefox extension installed, and Nord’s bespoke CyberSec feature automatically blocks suspicious websites and protects your devices against cyber threats and hackers. It’s simple to use, and Nord’s Auto Connect feature will always match you with servers offering the lowest ping and latency. Jumping between servers is just as easy and there’s plenty of choice in terms of locations, with servers in over 80 worldwide territories.

It’s taken it a while to catch up with other providers, but Hotspot Shield finally added a Firefox extension in September, and it offers lightning-fast speeds thanks to its proprietary Hydra protocol. The proxy app for Firefox means you don’t need to install the VPN and run it as a separate program and it’s free to download if you’ve taken out a premium subscription with Hotspot Shield – which is essential if you want to experience its full suite of security features. The free plan is very basic with restricted bandwidth, so we’d recommend avoiding it. 

You won’t be able to access all of Hotspot Shield’s VPN locations using the Firefox extension, but you can still gain a connection to locations such as the UK that are needed to unblock ITV Player and BBC iPlayer. It’s one of the easiest VPNs to use, and security features such as DNS/IPv6 and WebRTC leak protection will prevent your ISP and anyone else from discovering your true location or IP address while you’re connected.

Surfshark operates with a trusted no-logging policy to guarantee your privacy, and it’ll bite chunks out of anyone geo-blocked website it encounters while you’re surfing the net. All it takes is two clicks to set up the Surfshark Firefox extension – just click on the VPN to open it and then connect to one of over 1700 optimized servers to hide your IP address. Surfshark provides its own DNS on all of its servers, so you’ll never have to worry about any troublesome leaks either. 

The biggest selling point is the subscription prices, which start from just $1.99 per month. That’s incredible value for money, especially when you consider all of its subscriptions include CleanWeb, a bespoke security feature that blocks ads, trackers, malware, and phishing attempts made on your Firefox browser. And while some providers only support connections for up to five or six devices, a Surfshark subscription lets you protect every single device in your home with unlimited simultaneous connections.

ZenMate has one of the best Firefox extensions available for Mac, Windows, iOS, and Android devices. Using a VPN might sound complicated but it should never be stressful, and ZenMate has done everything it can to take the headache out of switching between servers. The interface is pleasing on the eyes and incredibly simple to navigate, providing instant connections to servers in over 74 countries. This also means you can use ZenMate to unblock region-locked content on Netflix, on HBO and Hulu. 

Security features include a kill switch, DNS leak protection, and AES 256-bit encryption, so your IP address will be completely masked when you’re browsing Firefox with ZenMate. Speeds were impressive and fast enough to stream Netflix in Ultra HD without any lag or buffering.

CyberGhost’s VPN Firefox extension lets you float straight through geo-restrictions, censorship, and all-round digital limitations by encrypting your internet traffic to make your online activity completely anonymous. As it’s based in Romania, it doesn’t fall within the five-eyes, nine-eyes, or 14-eyes jurisdictions, and operates with one of the strictest privacy policies we’ve seen, meaning you can trust CyberGhost with your personal information.

CyberGhost also has one of the largest networks out there, comprising over 6000 servers that have been optimized for online gaming, streaming, and P2P activity, making it a favorite amongst torrenters. That means it’ll sneak past the geoblocks that are used by some of the world’s biggest streaming apps such as Netflix and Amazon Prime Video too. With unlimited bandwidth, you can say goodbye to data caps and stream until your heart’s content on any of your devices.

PureVPN recently updated its VPN extension for Firefox, which acts as a one-click solution for all of your streaming and downloading needs. It’ll mask your internet activity completely by swapping your IP address with one of the many thousands from its vast network, and all of the information you’re transferring from your browser is protected with AES 256-bit encryption. There’s built-in protection against WebRTC leaks too and with unlimited server switching, you won’t have any issue finding the fastest speeds for streaming Netflix and Amazon Prime Video. 

Unlike other providers, PureVPN lets you connect to all of its 2000+ servers directly from the Firefox extension, and one account supports up to ten simultaneous connections, making it perfect for larger households. There’s a 31-day money-back guarantee and Pure’s friendly customer service team is available on live chat 24/7/365.

IPVanish’s super-slick Mozilla extension adds an extra layer of security to your internet connection with military-grade encryption and IP address masking. With WebRTC leak protection included, you won’t have to worry about your IP address leaking and your ISP finding out what websites you’ve been visiting. Connecting to the app is easy and just takes a couple of clicks, and once you’re up and running, you’ll be able to stream Netflix and Amazon Prime Video from most countries in the world. 

The extension is easy to navigate and lets you connect to IPVanish’s full network of over 1500 servers. Speeds weren’t the fastest our researchers have experienced, but the connections were consistently strong, supporting Ultra HD streaming. There are plenty of pricing options, and monthly subscription costs start from $2.40 per month for a two-year subscription, making it one of the cheapest providers out there.

Though TunnelBear offers a free plan, stay clear of it. It only offers base-line protection and isn’t strong enough to provide the security features you need to keep you safe on Firefox. Besides, $3.33 per month for a VPN subscription is fantastic value, especially when TunnelBear’s VPN includes unlimited bandwidth, AES 256-bit encryption, a kill switch, DNS/IPv6 leak protection, and unlimited server switching. As it operates with a strict no-logging policy, which is also independently audited by a third-party cybersecurity company, you won’t have to worry about your personal information being bear-handled. 

Sure, its server network isn’t the same size as larger providers such as CyberGhost or NordVPN, and that does mean you’ll only be able to unblock Netflix and Amazon Prime Video in the US, but if you’re looking for a user-friendly Firefox extension that runs smoothly in the background of your desktop, this is it. No complicated configurations required, TunnelBear is a simple VPN that delivers all of the basic features you need to keep you safe when you’re browsing.

Formerly known as Hide My Ass! VPN, this UK-based provider operates a network of over 1100 servers in 190+ countries, making it a powerful tool for unblocking region-locked websites and streaming apps straight from your Firefox browser. The Firefox app works by encrypting your data, preventing it from being accessed by third parties and hackers. There’s a built-in ad-blocker and malware scanner to keep you safe; plus, additional features such as the Tab Killer and Auto Disguise are perfect for hiding your internet traffic from your ISP.

It’s simple to use, and you can access all of HMA! VPN’s servers from the Firefox extension alone. Speeds were consistently strong, although our researchers did report large dips when they were connected in Japan. If you’re looking for a lightweight proxy extension that won’t drain your CPU in the same way as native apps, this UK VPN is a decent choice.
