When taking a look at the three best VPN browser extensions for Mozilla Firefox from our sample, you might notice a few exceptions to this rule, however. In short: A VPN browser extension only protects your browser's data traffic, and even then, with comparatively weak encryption, whereas a VPN client shields all traffic sent over your Internet connection, not only that emanating from your browser. Their efficacy depends, to a great extent upon the type of encryption they use: While qualitative VPN clients rely on protocols like OpenVPN, browser extensions tend to utilize less robust encryption. As such, browser add-ons create proxy connections that only have an impact upon their traffic, as opposed to that of your entire device. By and large, these aren't VPNs at all, since such networks are only created at the operating system level, routing all data traffic from your computer to others, and not just that of a single program or app.

Adds another layer of privacy everywhere you use the Firefox browser. So far as browser extensions are concerned, referring to them as "VPNs" is often a bit technically inaccurate. Use the lightweight Firefox extension to enhance the security of your connection.
