Before entrusting your browsing history and other sensitive information to a VPN, be sure it has a credible privacy policy and the processes to enforce it.

CyberGhost VPN exists to ensure you can browse, shop, stream, and torrent securely and privately. We’ve backed up our industry-leading no-logs policy with RAM-only servers that wipe your VPN session data with every reboot. And with our headquarters in Romania, a country with no data retention laws, we’re not obligated to log and keep your search logs.

This is how we guarantee no one will ever know what you’ve been up to – not even us.

Why You Need a VPN for Android

Rely On Iron-Clad Security

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.

A VPN can slow down your connection unless it’s built for speed.

CyberGhost VPN has blazing-fast 10-Gbps servers, so you never have to worry about your sluggish VPN ruining movie night.

It could also be your ISP that’s slowing down your connection. If so, use CyberGhost VPN’s free Firefox extension to bypass content-based throttling and reclaim the speeds you pay for.

Sign up for CyberGhost VPN and secure your connection with the fastest VPN protocols, including OpenVPN and the lightweight WireGuard®. Let our app select one for you, or customize your connection with a quick visit to settings.

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 100 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 100 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 100 countries, streaming-optimized servers, and 24/7 live chat support.
