4 Best VPN Add-ons for Firefox in 2024
Our experts have reviewed 53 VPN providers, which were put through extensive rounds of testing. To learn more about that process, here’s how we review VPNs, where we explain our criteria and our policy of being fully transparent.
Firefox is pretty privacy-friendly as far as Web browsers go. However, it doesn’t, and can’t, hide your IP address from the services you access. This effectively means it can’t stop hackers, prevent your Internet service provider (ISP) from selling your data, or even help you bypass annoying geo-blocks on streaming sites. For all of this and more, you’ll need the best VPN for Firefox. That way, you can keep your data private while browsing online.
VPN add-ons mask your IP address while using Firefox and other popular browsers. They keep your physical location a secret, even while browsing geo-blocked services as if you were physically located elsewhere.
Also, a good Firefox VPN extension will encrypt your traffic so it can’t be read by hackers on unsecured networks. Some of the best VPN services even include HTTPS Everywhere and WebRTC blocking in their add-ons to holistically protect you.
Finally, our guide also includes VPN extensions that offer ad-blocking, tracker filtering, and even anti-phishing features. That said, here’s how you can install the best VPN for Firefox and stay safe while browsing.
How to Add a VPN Extension in Firefox
Installing a VPN add-on for Firefox is a straightforward process. All you need to do is sign-up and download the provider’s extension from their website or Firefox’s Add-on Store. Here’s a step-by-step guide to installing a safe and easy-to-use VPN for Firefox:
- Sign-up for the best VPN extension for Firefox (such as NordVPN).
- Download the add-on from the provider’s website.
- This should redirect you to Firefox’s Add-ons page.
- Click “Add to Firefox” to install the VPN extension in your browser.
- Press “Add” in the browser notification to allow the installation.
- Click on the extension and sign in with your account credentials.
- Select a server and/or press “Connect.” That’s it!
Note that some VPNs require you to install their full app as well. There are also those that come with standalone Firefox VPN add-ons. For more info, turn to our guide that explains how to set up a VPN on Firefox.
Best VPN Extension for Mozilla Firefox
The best VPN for Firefox should give you access to a worldwide network of high-speed servers. Naturally, the VPN provider shouldn’t keep user logs and be free of any IP, DNS, or WebRTC leaks.

Why Do I Need a VPN Add-on for Firefox?
Using the best VPN add-on for Firefox will help you hide your IP address and encrypt your browser traffic. It’s a more lightweight solution than installing a full-on VPN for Firefox (or any browser) to stream geo-blocked content online. We’ve listed more advantages below:
- Browser Privacy and Security: The best VPN extension for Firefox will hide your IP (and true location) from any sites you visit. Not to mention, your ISP or any other third parties won’t see what you do online.
- Watch Geo-Blocked Content: Streaming Netflix or other services through Firefox? Use a VPN add-on to quickly switch to different countries to explore their vast library of TV shows and movies.
- Bypass Internet Censorship: With the best VPN for Firefox at your disposal, you won’t need to worry about government censorship or annoying firewalls at school or work.
- Block Ads and Malicious Sites: Some of the best VPN for Firefox, including extensions, come with in-built ad-blocking and also deal with intrusive trackers, phishing websites, and more.
Firefox VPN Extension vs. VPN App: Which One Should You Use?
Obviously, the smart choice is to get the full VPN app instead of a Firefox VPN add-on.
A native VPN app offers all the advantages of a Firefox VPN extension but can additionally safeguard your traffic from all other apps on your device(s). Moreover, some features may be exclusive to the complete app, as you’ll see below.
As you can see, the main advantages of a Firefox VPN add-on are limited to faster speeds and being more lightweight. This is partially due to not providing full encryption.
While that may be useful for you if you have a slow connection, it may put your privacy and security at risk. Especially if you run sensitive apps outside Firefox without a full VPN app, like online banking apps and other programs that handle valuable personal data.
Can I Use a Free VPN Extension for Firefox?
You can use a free VPN extension for Firefox, but you’ll find it much more limited than a full VPN or even a subscription-based Firefox VPN extension.
For example, Zenmate’s free Firefox extension can still be used to protect your data, mask your IP, and bypass some blocks. However, the free version limits your speeds, available locations, and the ability to bypass stronger VPN filters (such as those on Netflix).
Moreover, most free VPNs (and free Firefox VPN extensions) can log your data or inject advertising into your browser. As they need to cover operational costs without a subscription, ads and selling browsing data is their only monetization option.
If you’re looking for a full-fledged free VPN instead of a Firefox add-on, follow the link and check out our recommended safe and reliable options.
Final Thoughts
The best VPN for Firefox can be a more lightweight alternative to a full VPN app. You get all the same traffic-hiding, IP-masking, and geo-block bypassing capabilities - limited to your browser only. Of course, we recommend going with a dedicated VPN app.
Fortunately, you don’t have to compromise. Use NordVPN’s Firefox add-on to control the app directly from your browser. Plus, it gives you full protection for all your traffic, excellent unblocking capabilities, and 5,800+ blazing-fast servers in 60 countries - which makes it the best VPN for Mozilla Firefox in 2024.
