Frequently asked questions

How do you activate NordVPN on Mozilla Firefox?

Once you have logged in to your account, activating NordVPN is easy. Go to the NordVPN extension on your browser and click the Quick Connect button. You will be connected to the best server available. If you need a precise region, click the Connect to a specific country button, and choose the location. You can tweak your add-on’s security features, including designating websites that you want to access without VPN protection, in the Settings panel.

How do I use a VPN in Firefox?

The NordVPN extension for Firefox offers additional privacy tools that you may find handy. It blocks WebRTC — a protocol which may leak your IP — by default. Additionally, you can enable the CyberSec feature — it blocks ads and protects you from entering dangerous websites. You can find both in the settings panel of the extension.

What is a VPN for Firefox?

The NordVPN extension for Firefox connects you to a virtual private network, rerouting and encrypting your browser’s traffic through a remote server. The add-on also hides your IP in the process, so you can browse privately. One of our VPN’s additional features blocks WebRTC, ensuring that your data is protected from potential leaks.

Keep in mind that the add-on only protects online traffic going through your Firefox browser — anything else you do on your device will not be encrypted. To shield all of your other online activities, download our native VPN apps for Windows, Android, iOS, or other popular operating systems — they come free with your NordVPN account.

What is the best free VPN for Firefox?

Don’t be tempted by allegedly free VPNs for Firefox — if you skimp on security, your internet privacy ends up paying twice. Most free VPNs offer only a handful of servers, slow down your connection, and put you at risk due to security vulnerabilities. Some even resort to selling user data to third parties, including unscrupulous or malicious entities, to cover running costs.

Instead, look for deals or sales from reliable VPN providers. For example, NordVPN offers a hefty discount on its longer plans, meaning that you can get the best VPN on Firefox for less than one cup of coffee a month!
