Best VPN for Firefox
Mozilla Firefox is becoming an increasingly popular browser choice for those looking to switch from Google Chrome, however other than a few extra features it doesn’t actually protect your privacy any more than Chrome does.
This is why it’s essential to use a VPN to keep your ISP from viewing everything you do online, as well as protecting your confidential data from potential snoopers and hackers.
Our top picks for Firefox offer a smooth, lightweight experience for heavy browser users while protecting your privacy with WebRTC blocking and minimal (or even zero) logging.
Here are the Most Important Factors When We Review a VPN
- Has a secure browser extension for Mozilla Firefox
- Quick and easy to set up on your browser
- Reliable and fast speeds
- Useful privacy features
- Transparent, fair, and privacy-focused logging policies
- Range of well-designed and easy to use apps

The Bottom Line
ExpressVPN is the most reliable VPN on the market hands down, and it’s no different when it comes to Mozilla Firefox protection.
ExpressVPN’s extension is more than just a proxy as it works with the desktop app to encrypt all internet traffic across all your device’s applications.
It also offers some advanced security features including a VPN kill switch and protection against WebRTC leaks and a sensible minimal-logs policy.

The Bottom Line
NordVPN isn’t as reliable as ExpressVPN but it’s still a good choice for Firefox – and it’s far cheaper too.
NordVPN’s Firefox extension is a proxy, so while it’s a great lightweight solution for heavy browser users it will only encrypt your browser traffic.
We do love NordVPN’s strict zero-logs policy, though, and the ‘Block WebRTC’ feature. The desktop apps also offer loads more advanced privacy features.

Surfshark is a fairly new zero-logs VPN but it shows a lot of promise – its secure Firefox proxy extension is a welcome bonus.
It offers Firefox users integrated WebRTC blocking and a ‘CleanWeb’ tool which aims to block ads, trackers, and malware.
Even more reassuringly, Cure53’s recent independent audit of the extension proves its high level of security.

The Bottom Line
KeepSolid VPN Unlimited is a beginner-friendly VPN with a streamlined browser extension for Firefox.
Like the other proxies on this list, it only encrypts browser traffic, and has a useful feature that blocks WebRTC.
Unfortunately, it is based the US, though, and also temporarily collects your IP address.

How to Use a VPN for Firefox
Before you begin using a VPN on Firefox, you’ll have to decide whether you’re going to opt for a paid subscription or use a free service.
Free Firefox extensions are almost always proxies that mask your IP and allow you to access blocked content, however they won’t encrypt your web traffic, so the owner of the server you connect to will still be able to view your browsing history. Most of them are also subject to very restrictive data caps (around 500MB) so you’ll be very limited to what you can actually do online. If you pay for a subscription you’ll be able to use it on other apps as well as Firefox, and also won’t have to put up with running out of data at any point.
Once you’ve chosen your provider, installing the Firefox extension onto your browser is simple and takes just minutes to set up – for detailed instructions take a look at our guide on How to Install a VPN on Firefox. After that, using a VPN on Firefox is pretty much the same as using it on any other platform. All you have to do is choose a location and you’ll appear to be connecting out from that location – this means that anyone trying to track you won’t be able to see where you really are.
For the quickest possible speeds, you’ll want to choose a server as close as you can to your physical location. Most providers have an automatic setting that’ll do this for you, but if not, just choose one that’s in the same country and you shouldn’t have any issues.
Once you’re connected to the VPN, simply carry on using Firefox as you normally would. It’s important to remember that if you’re just using the Firefox extension and no other form of VPN app (i.e. desktop or mobile) you’re only masking the IP of your browser traffic. This means that any apps you use outside of your browser (such as Spotify) aren’t protected and are visible to your ISP and potentially other third parties. In most cases, we’d suggest using the extension on top of the desktop app for the highest level of privacy.
How to Choose a VPN for Firefox: 7 Tips
- Does it offer a Firefox extension?
All top-tier VPN providers offer custom apps for desktop and mobile, however only a handful offer decent extensions for Firefox browsers. Our top picks all boast sleek, user-friendly Firefox extensions that encrypt your browser traffic securely – be wary of proxies that spoof your IP address but leave web traffic unencrypted.
- Does it offer fast, consistent speeds?
There’s not much point choosing a VPN with a great Firefox extension if sub-standard performance is going to limit what you’re able to do online. As a general rule, the faster speeds, the better, and you should also look for low latency on local servers for a seamless browsing experience.
- Does it have servers in the locations you need?
In order to get the best possible performance, you need to choose a VPN server close to your physical location. A higher number of individual servers tends to mean less congestion and improved speeds but unfortunately this isn’t always the case.
Take a look at our speed test results to get the best idea, especially if you’re looking to connect to a specific country.
- Will it work with your favorite websites and apps?
Do you enjoy using streaming sites such as Netflix or BBC iPlayer? Not all VPNs will work with these websites. We are continuously testing whether each VPN is working with Netflix and other popular sites, and share these results in our VPN reviews.
- What is their logging policy?
Most VPNs will claim to be completely “zero logs” but this is almost never the case. In order to deliver a decent level of server performance across a worldwide network, most providers will need to monitor at least some user connection details to ensure servers aren’t becoming overcrowded.
We summarize providers’ privacy policies in plain English in the logging policy section of our reviews, meaning you don’t have to spend your time reading through them all. Ideally you want to choose a provider that doesn’t log any details that could be used to personally identify you, or even better, one that doesn’t collect any logs whatsoever.
- Are their client apps and software easy to use?
Most of you aren’t only going to be using a VPN with Firefox, so you need to choose a provider that offers a good range of custom apps designed for both desktop and mobile. Look for a VPN with software that’s well-designed, user-friendly and powerful and you will be much more likely to use it on a regular basis.
We share the results of our hands-on testing of each VPN app in the the Ease of Use part of its review. We spend all day testing VPN apps, so hopefully we know a thing or two!
- Finally, check the price and money-back guarantee
Even the most expensive VPN plans are very affordable but you will likely have a budget in mind.
12-month plans typically offer the best value and you can reduce the risk of buyer’s remorse by choosing a VPN with a long refund period, preferably 30 days and with no questions asked. These guarantees are much more common than traditional free trials but are essentially the same thing.
