Why Should I Use a VPN Firefox Extension?

By using a VPN for Firefox, you can successfully encrypt your browser activity and control the VPN from within your browser. The main benefit of using a VPN browser extension is the fact that you don’t need to leave your browser to access the app to switch servers.

Moreover, many VPN browser extensions offer users the option to solely protect traffic in the browser, meaning that all other internet activity outside the Firefox browser is tunneled via your regular network. This means you can enjoy an overall faster internet connection, as the VPN won’t be slowing down your entire system.

VPN Firefox browser extensions can also offer extra privacy features such as WebRTC protection and ad-blocking to keep your browsing safer. Therefore, there are many reasons for using a VPN browser extension for Firefox.

Is There a Free VPN Extension for Firefox?

Yes, there are plenty of free VPN proxies for Firefox. Would we recommend them? No, and here’s why. Free VPNs pose a serious security risk since they often access your data and sell it to third parties. Moreover, free VPNs lack the extra features that the providers above offer, like malware protection. If something is free, you have to ask yourself, why is this? More often than not, it is because the product itself isn’t worth paying for.

Yes, Mozilla, the company behind the Firefox browser, has released a VPN. Mozilla VPN is a great service with a strong focus on security and privacy; however, it doesn’t yet offer a browser extension for Mozilla Firefox which is ironic.

A VPN extension for Firefox is a great choice for people who want to only encrypt internet traffic in their browser and not encrypt other app data. As well as this, VPN browser add-ons make it easy to enable and disable the VPN without having to open third-party apps and leave your browser.


  • Protect all the data in your Firefox browser
  • Doesn't affect other apps
