Mozilla Firefox is one of the most popular privacy-focused browsers available. It frequently incorporates features for improving user confidentiality and keeping them anonymous.

However, there’s only so much a browser can do by itself. Which is why netizens should supplement their web surfing activities with a VPN (Virtual Private Network). It will encrypt your web traffic and make it unreadable to potential interlopers.

Of course, top-notch internet security shouldn’t always come at a price. That’s why we picked only the best free VPNs for Firefox. They’re not as great as premium options, but they will get the job done.

Should you use a free VPN for Firefox?

Although virtual private networks can be free or premium, the best VPN services are always paid. This principle applies to all use cases, including streaming video content, web browsing, and online gaming.

Luckily, some free VPNs are good enough if you’re on a tight budget and don’t mind a few limitations. For starters, some no-cost services are available only temporarily, while others provide a limited amount of monthly browsing data. Plus, connection speeds, available servers, and features are toned down as well.

That being said, if your goal for using a free VPN for Mozilla Firefox is security and privacy, a free virtual private network will work. Just keep in mind that you’ll have to keep an eye on data caps and will experience longer than usual loading times while using a Firefox free VPN add-on.

But if you want 4K-ready speeds, wide-reaching server networks, and diverse device compatibility, consider premium Firefox VPN options. Plus, most of them have dedicated browser extensions for greater versatility.

You may know that there are hundreds, if not thousands, of free VPN services available. Unfortunately, potential customers should avoid most of them due to security and privacy issues. They likely collect and sell user data or engage in other nasty practices to stay afloat.

Instead, we recommend freemium providers as it’s clear how they manage to maintain the service. Besides that, we picked free VPN for Mozilla browser options with essential security and privacy features, such as:

  • AES-256 encryption
  • A reliable kill switch
  • Modern tunneling protocols
  • Ad and tracker blocking
  • Reasonable data caps
  • Apps for desktop and mobile devices

Unfortunately, the free plan is unusable for P2P or streaming, and a ProtonVPN extension for Firefox doesn’t exist yet.

Another freemium Firefox VPN worth considering is Hotspot Shield. This virtual private network is blazing-fast with its proprietary Hydra protocol and wide selection of servers. However, the free plan is fairly limited and suitable for specific use cases.

For starters, unpaying users have to deal with only 500 MB of daily browsing data.

How we picked the best free VPN for Firefox

Here’s a detailed look at what criteria we considered when sifting through free Firefox VPNs. Keep these in mind if you wish to look into alternative virtual private network options.

  1. Free plan availability and subscription price. Unsurprisingly, the primary criteria for choosing these VPN providers is the option to use them for free. However, premium subscriptions should be reasonably priced if customers decide to unlock the complete package. Meanwhile, fully free services are out of the question because they can’t be trusted.
  2. Device compatibility. The VPN free plan should, at the very least, be compatible with desktop and mobile devices, the main web browsing platforms. Naturally, a free VPN extension for Firefox would be ideal, but that’s hard to come by with freemium services.
  3. Security features. Unprotected web browsing could expose you to malicious ads, viruses, and malware. It’s vital to pick a VPN with security measures against these digital threats. Just remember that a free service doesn’t compare to the most secure VPN options.
  4. Connection speed. Costless VPNs typically throttle bandwidth to a certain degree to ensure minimal network congestion and peak performance for paying customers. However, this speed reduction is barely noticeable if modern tunneling protocols are available, for example, WireGuard.
  5. Server number and country diversity. Free VPN users get the bottom of the barrel in terms of server and country options. Still, three locations are better than one. Plus, we had to take into account the potential from the premium subscription.
  6. Privacy practices. Although Mozilla Firefox is quite confidential by itself, the VPN should enhance it further, not undermine it. Therefore, we chose providers with zero-logs policies and jurisdiction far away from the gaze of the Five Eyes alliance.
  7. Customer support options. Unfortunately, unpaying users are usually low on the priority list in the customer support department. However, the ticket backlog will be dealt with quicker if there are 24/7 assistance options.

How to set up a Firefox free VPN add-on

Every Mozilla Firefox user is aware that they can look through available add-ons from the settings menu. However, that’s not always the most reliable method when looking at the best free VPN browser extensions for Firefox. That’s because there’s the possibility of stumbling upon imitators of well-known brands. These fake extensions are a security threat that netizens should avoid at all costs.

NordVPN Firefox official add-on

The most fool-proof way of dodging these is by going to the source directly. That means visiting the VPN provider’s website and downloading the Firefox free VPN add-on from there. Alternatively, you can opt for the fully-featured application for your browsing device for greater security. After all, a virtual private network app is much more powerful than a browser extension.

In any case, here’s a step-by-step guide to the whole process.

  1. Pick one of our recommended free Firefox VPN services. My go-to provider is NordVPN
  2. Visit the provider’s website and navigate to the page where all available apps are displayed
  3. Click the link redirecting you to the Firefox Browser add-ons page of the provider
  4. Download and install the free VPN for Mozilla browser
  5. Open it and log in with your account
  6. Connect to any server location
  7. Surf the internet securely and privately!

Difference between VPN browser extensions and apps

As mentioned previously, VPN browser extensions are a bit different from conventional VPN applications most people use on a daily basis. For example:

  • Browser extensions usually have different features from the full application
  • It’s technically not a full-fledged VPN, but a proxy (what is 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. Plus, there’s nothing stopping you from combining the two for ultra-fortified security.

Mozilla free VPN not working: solutions

Whether you’re using a Firefox add-on or VPN app, you may occasionally encounter issues. Thankfully, you’re just a few knowledge tidbits away from solving these nuisances. You can try these fixes before losing your cool and contacting customer support.

  • Switch servers. The most frequent VPN-related issue pertains to faulty servers or blocked IP addresses. Luckily, the fix is simple – just connect to another one.
  • Check for IP and DNS leaks. If you’re trying to unblock geo-restricted content unsuccessfully, your IP address or DNS requests may be leaking. You can check for those on websites like
  • Update your browser and VPN extension or app. Perhaps one of the puzzle pieces refuses to collaborate because it’s out-of-date. Try updating your browser, VPN extension or app, and see if the problem persists.
  • Delete other proxy add-ons. It’s common for software conflicts to arise when there are multiple proxy extensions and VPN applications installed. Uninstall unused software and try again.
  • Check your internet connection. Maybe it’s a fundamental problem with your internet connection? Make sure your connection works without a proxy or VPN enabled.


Enabling the best free VPN for Mozilla Firefox further enhances your anonymity and keeps you secure against trackers and malicious ads. Naturally, a costless service isn’t as great as a premium one, but it’s a solid introduction to the numerous benefits a virtual private network provides.

      Greetings, Vesa. Indeed, NordVPN and Surfshark aren’t entirely free, but they provide fully featured free trials. As such, we believe they’re worth considering. Plus, we don’t recommend using completely free VPNs anyway.
