    Which Firefox VPN Extension is the Best?

    We already revealed a little earlier in the text that NordVPN is our test winner. Now it's just important to explain why NordVPN wins our test and what alternatives are available. In the following comparison, we pay particular attention to how well the respective VPN providers have optimized their Firefox extensions and how secure they are.

    1st place - NordVPN Firefox browser extension

    NordVPN wins our comparison for two main reasons. The browser extension is easy to install and significantly more performance-optimized than the applications from other providers. That means it won't slow your computer down while the application is running. In addition, the NordVPN Firefox extension comes with great features such as an integrated ad blocker. As soon as you log into your NordVPN account, the browser extension automatically connects to the best available server. Important: If you use the Firefox extension, it really only protects your surfing with Firefox, but not other applications. So a Firefox VPN extension is more like a proxy than a VPN. We therefore recommend all-round protection and installation of the PC client.

    Further advantages of the NordVPN browser extension.

    • Over 60 locations to choose from
    • Very high security standards
    • Stream Netflix, Hulu, HBO, Amazon Prime and many more

    2nd place: CyberGhost Firefox VPN browser extension

    CyberGhost VPN logoCyberGhost ranks 2nd. Unfortunately, the CyberGhost Firefox VPN browser extension doesn't offer the same convenience as NordVPN, but it is 100% free.

    The CyberGhost application can run without an account and independently of the client application. The security standards of the free CyberGhost browser extension do not differ from the paid client. Unfortunately, CyberGhost strongly restricts the server selection of its browser extension compared to the client application. Only access to servers in the Netherlands, Germany, Romania and the USA is available.

    Even if you use the paid CyberGhost service, the Firefox browser extension is still limited to the same countries.

    However, streaming Netflix, Hulu and Amazon Prime Video using the browser extension works fine.

    Customer service is only available in English, but via the ticketing system or live chat.

    Conclusion: CyberGhost took second place in our test with its free Firefox VPN browser extension.

    SurfShark Firefox VPN browser extension

    SurfShark also provides a very good Firefox VPN browser extension for Firefox. The VPN runs in the background without disrupting surfing behavior and is user friendly and easy to install. Compared to the client application, the speeds are somewhat reduced, but to an acceptable extent. Unfortunately the browser extension is limited to 14 countries.

    What we also like about SurfShark:

    • Good security standards
    • Unlimited bandwidth
    • Good to very good speeds
    • Unlimited number of connections

    You need an active SurfShark account to use the browser application. 

    Conclusion: SurfShark is a solid Firefox VPN extension. However, speeds and server selection are better with other providers.


    If you want to surf safely in Firefox, you should use a Firefox VPN browser extension. Premium providers like NordVPN and SurfShark do a very good job and provide sophisticated, simple and user-friendly applications. We generally advise against most free providers as they are often not very secure. Furthermore, you should avoid any providers that do not require a login, as this can be exploited by hackers.

    In summary, if your security is really important to you, you cannot avoid using a full-fledged VPN client. Our tip: NordVPNto use our test winner as a full client.
