CyberGhost VPN unlocks websites

Ultra-Stable Connections

Access your favorite websites securely with CyberGhost VPN

Absolute Internet Freedom

Location restrictions are a pain. Many websites use your IP address to determine your location and restrict access if you’re traveling or living abroad.

We don’t want anybody to keep you from your favorite content. Use CyberGhost VPN for Firefox to change your IP address to one in a different country. We reroute your data through our encrypted servers to make it unreadable to third parties.

That means you can access streaming services and websites all around the world. Encrypt your data to bypass network restrictions or government censorship. Experience the internet as it was intended — with absolute freedom.

Does your internet slow down randomly for no reason? Chances are, your ISP is throttling you. They slow down your connection during peak hours if you reach a data cap.

You should get the internet speeds you pay for. Connect to CyberGhost VPN and encrypt your data. If your ISP can’t read your data, it can't throttle you. Problem solved!

Regain the internet with our free Firefox VPN. We help you defeat ISP throttling, and we never impose a data cap. That means you can connect for as long as you want.

CyberGhost VPN has a no logs policy

No ISP Throttling

Access your favorite websites securely with CyberGhost VPN

No Account Necessary

Some VPNs have confusing setup processes. They’ll make you create an account before letting you have complete internet freedom. You don’t need this hassle to get a Mozilla VPN.

Use the CyberGhost VPN Firefox extension without an account. Just install the extension on your browser to hide your IP address and encrypt your data. It’s that easy.

Subscribe to a paid CyberGhost account to get even more cutting-edge security features, including unlimited access to our massive private server network. Make CyberGhost VPN your go-to security app and gain online peace of mind.

It’s bad enough that websites and ISPs collect your data. Some VPNs do too! VPNs without a No-Logs policy collect your data and sell it to third parties, even to governments.

CyberGhost VPN has a strict No Logs policy. That means we’ll never track, store, or sell what you do on our servers. You can read our quarterly transparency report to see all the steps we take to keep you safe online.

Rest easy knowing your information is 100% secure. As long as you’re connected to a CyberGhost server, nobody can access your data.

As a rule of thumb, a Firefox VPN should always be kept on. However, if you're not a fan of having your Firefox traffic encrypted at all times, you should at least make sure to use a VPN when connected to public Wi-Fi networks, when you're traveling to a country where the internet is restricted, or when you want to spoof your location.

We highly recommend against it. Free VPN software will often cap bandwidth and only offer access to a limited server array. Additionally, free VPNs are notorious for making a profit by selling their users' online preferences to third parties. This contradicts one of the main purposes for using a VPN — privacy and anonymity.

While our free Firefox extension is a great tool for enhancing your online data security, it too has its limits. To get the full-fledged VPN experience, with access to all our high-speed VPN servers from 98 countries, multiple protocol support, and 24/7 Customer Support, we recommend trying our premium VPN.

Adding CyberGhost VPN to your list of Firefox add-ons is simple. Open the settings tab, click on the Add-ons and themes button (CTRL+SHIFT+A), type in CyberGhost VPN, and hit the Add to Firefox button. After that, make sure to turn on the app every time you open Firefox.

Our VPN add-on for Firefox is a great tool for increasing your online privacy while using Mozilla's browser. However, it has its limitations.

First of all, compared to the premium version, you only get access to 8 servers from 4 countries, as opposed to the many servers from 98 countries you can connect to with the full app. The add-on does not feature any of our dedicated streaming servers, and does not offer multiple protocol support, or 24/7 Customer Support.

Secondly, the Firefox VPN extension can only be used inside Firefox, while the full app lets you connect up to 7 different devices simultaneously.

To activate a VPN connection on Firefox, connect to your preferred server location in your VPN app. A VPN encrypts your internet traffic and masks your IP address, enabling secure, private browsing without any additional adjustments. For direct activation of a VPN add-on in Firefox, install an extension and enable it.

CyberGhost VPN has dedicated apps for Windows, macOS, Linux, Android, and iOS. You can even install our free VPN extension for Firefox. Note that VPN add-ons in Firefox only protect web browser traffic, not all your online activity.

No, Firefox itself doesn't have its own built-in VPN software. That said, the creators of Firefox made a standalone VPN product, called Mozilla VPN.

To download a VPN add-on in Firefox, start with accessing the Firefox Browser Add-ons page. Search for your preferred VPN extension and click the Add to Firefox button to install it. Launch the add-on from your Firefox toolbar and turn it on.

CyberGhost VPN offers a free Firefox extension available for download in the Firefox Browser Add-ons page. You can also download our Firefox extension directly from our website.

A VPN for Firefox is a virtual private network service designed to protect your digital privacy and online security. It routes your internet traffic through a secure tunnel, encrypts your online activity, and masks your IP address.

You can use the CyberGhost VPN Firefox extension for free, without having to create an account. You just need to install our Firefox add-on on your browser.

Subscribe to a paid CyberGhost account for advanced security features designed to secure all your web traffic. Enjoy access to ultra-fast servers in 98 countries, streaming-optimized servers, and 24/7 live chat support.
