What is a Firefox VPN proxy extension?

A Firefox VPN extension is a lightweight browser add-on that encrypts traffic and changes your IP address. In addition to encrypting your browser traffic and changing your IP address, NordVPN’s browser extension for Firefox includes useful features like Threat Protection. However, for full protection, it’s best to pair it with the NordVPN app, which offers Threat Protection Pro™ — a feature designed to provide advanced security and anti-phishing solutions that extend beyond the Firefox browser.

The benefits of using VPN add-on for Firefox

A VPN add-on for Firefox provides just some VPN benefits, when it comes to browser security, NordVPN’s Firefox browser extension is as good as it gets.

Customize the Firefox VPN proxy extension to your needs

Using split tunneling, you can choose which websites you want to route through a VPN proxy extension and which to exclude from it. This way, the excluded websites will be able to see your real IP address.

Protect your IP address

With the Mozilla Firefox VPN proxy add-on, you can hide your IP address from malicious actors, keeping your online traffic safe. Forget about third-party snoopers and security flaws such as WebRTC leaks simply by connecting to our Firefox VPN proxy extension’s secure servers.

Block ads and malicious websites

Threat Protection blocks suspicious websites and guards you against cyber threats, letting you access any website safely. Enable Threat Protection through NordVPN settings in the top-right corner of your browser to enjoy fast connection with more privacy and security.

Avoid location and timezone mismatches

Use spoofing to prevent websites from restricting your access because of a discrepancy between your system clock and your purported location.

Forget about data tracking

Data misuse is rampant these days. But don’t worry — NordVPN’s Mozilla Firefox VPN proxy add-on doesn’t collect your private network data — it’s simply designed not to.
