Frequently asked questions

How do you activate NordVPN on Mozilla Firefox?

Log in to your NordVPN account and add the Mozilla Firefox extension to your browser. Go to the NordVPN extension in the top right corner of your Firefox browser and choose a VPN server to connect to. Alternatively, click “Quick Connect” and NordVPN will find and connect you to the best available server.

How do I use a VPN proxy extension on Firefox?

Using a VPN on Firefox is easy. Add the VPN proxy extension to your Firefox browser, and connect to a VPN server to enjoy online protection.

The NordVPN proxy extension for Firefox offers several handy privacy tools. It blocks WebRTC — a technology that may leak your IP. You can also enable Threat Protection Lite to block ads and protect you from visiting dangerous websites. You’ll find both in the settings panel of the extension.

What is a VPN for Firefox?

The NordVPN extension for Firefox is a proxy that redirects your internet traffic to a more secure version (HTTPS) of the website you’re accessing. The add-on also hides your IP address, so you can browse privately. One of our extension’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 — they’re typically not very secure. Most free VPNs offer only a handful of servers, slow down your connection, and put you at risk due to security vulnerabilities. Some even sell user data to third parties 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 Firefox VPN proxy for less than one cup of coffee a month!

Do I need the VPN app if I have a VPN extension?

Yes! Proxy extensions are great when you want to quickly change your IP address. But NordVPN’s desktop apps offer many more features, like Meshnet, Threat Protection, Kill Switch, and Dark Web Monitor. You can also change the VPN protocols you want to use, connect to specialty servers, and view your statistics.

Enjoy a hassle-free online experience with NordVPN

Hide your virtual location, get a new IP, access the internet without restrictions, and enjoy your favorite content while traveling with a risk-free VPN. If you are not 100% satisfied, tell us within 30 days of the purchase date and get a full refund.
