Top 5 best free VPNs for Mozilla Firefox

Is it worth installing a free VPN for Firefox?

While a free VPN will give you some additional protection, it might not be the best option if you're serious about your VPN usage. In this case, it’s always best to look into paid VPNs.

Even though it has limited functionality compared to a premium VPN subscription, it’s suitable for lightweight use and casual browsing.

Should you pick a VPN extension or app for your browser?

Choosing between a VPN (Virtual Private Network) extension for Mozilla Firefox and a client app for your device might be difficult because the distinction between the two is not always evident.

A VPN extension is a simple plugin or add-on used to make a quick VPN connection. It’s a lightweight version of a VPN app and operates only at the browser level. Meaning that none of your devices will be secured. It hides your original IP address and keeps your Firefox browser activities anonymous.

On the other hand, a VPN app, or a VPN client, is a VPN application that creates and encrypts a tunnel between a server and your entire device. No matter the browser or device, once it’s connected to a VPN app, it is secured and passes through an encrypted connection safeguarding your data from any cyber threats.

So the answer to which option you should choose really depends on your needs. If you only need a secure browser – a VPN extension for Firefox is just the right fit. However, if you’d like to secure multiple devices (your laptop, phone, router, or another smart device) simultaneously with a single account, a VPN app is the way to go.

Try NordVPN for your browser
