What Is a VPN Extension for Firefox?
A Firefox VPN is an add-on that helps improve your privacy in the browser. It encrypts your connection and routes your traffic through a VPN server, which assigns you a new IP address. This can help reduce extensive tracking while you browse. However, the extra protection covers only your activity within the browser.
Connect to Secure Servers for Firefox
Pick a location and go. The CyberGhost VPN Firefox extension lets you connect to our servers in the US, Germany, the Netherlands, and Romania, so you can switch regions in seconds and browse with a bit more privacy.
Need other server locations? The full CyberGhost VPN app gives you access to a much wider network plus extra features across your entire device — not just your browser. If you’re curious, you can try it out with our 45-day money-back guarantee (14 days on our monthly plan).

Privacy Boost for Firefox and Beyond
Many browser extensions make you jump through hoops to use them. We keep things simple. With the CyberGhost VPN Firefox extension, you can connect in just one click. No lengthy registration and sharing your email address required.
If you need coverage beyond your browser, CyberGhost VPN comes with handy apps for Windows, macOS, iOS, Android, and Linux. This extends your security boost above your in-browser activity, helping protect your streaming apps, gaming, P2P activity, and more.
Got gadgets without native VPN support? You can set CyberGhost VPN up on a VPN-compatible router. Doing so automatically connects all devices on the network, including game consoles and Smart TVs, to the same VPN server.

Why You Need a VPN for Firefox
When you use a Firefox VPN extension, your browser traffic is routed through a VPN server before it reaches any websites. This means services see the server’s IP address rather than your own. By using a different IP address, it can be harder to link your browsing activity back to you, which helps reduce tracking.
Keep Your Real IP to Yourself
Boost Security for Your Logins
ISPs, websites, and even your government can track and monitor your browsing habits over an unencrypted connection. Worse, using public Wi-Fi without a VPN can expose you to cyber attacks.
Secure your connection with our free VPN extension for Firefox. All it takes is a click to keep any prying eyes out of your business. We use military-grade VPN encryption to cover your browsing tracks, so even the smartest snoop doesn’t stand a chance.
Our premium VPN gives you even more security with features like its built-in kill switch. This temporarily cuts your connection on patchy Wi-Fi to prevent data leaks if your connection drops. Our automatic Wi-Fi protection feature will also secure your traffic the second you connect to unknown networks.
Sometimes you just want privacy in Firefox, not a full-device makeover. A VPN extension can help protect your Firefox browsing traffic without affecting your apps, updates, or background processes. Flip it on from the toolbar when you need it, and switch it off just as fast. Simple, clean, and on your terms.
Keep It Light, Keep It More Private
Not all internet traffic gets the same treatment. During busy hours, ISPs can slow some activities down more than others. Using a VPN in Firefox encrypts your browser traffic. That can help reduce the chances of activity-based slowdowns and keep your browsing more consistent when networks are under pressure.
