3 Best Mozilla Firefox VPN Extensions That Work in 2021

A VPN is an amazing software tool that encrypts your data and lets you browse the web securely. But did you know that a lot of VPNs come with Firefox extensions?

For those of us who prefer to use Firefox, having a VPN extension is a must. Instead of minimizing your browser, turning on your VPN, and then refreshing your web page, you can just click on the extension and know you’re protected.mIn addition, if you only need to encrypt your traffic on Firefox, then there’s no point to turn on the software on your entire device. A Firefox extension uses much less data but still secures your internet activity.

Not all VPNs have an extension for Firefox though, and some of them work differently. Our top choice is ExpressVPN, the extension is extremely lightweight, it has excellent security features, and it offers a 30-day money-back guarantee.

Don’t worry, there are a lot of other options too. We’ve rounded up the best VPNs with a Firefox extension and will explain the pros and cons of each.
