Firefox is one of the best cross-platform browsers used on most modern devices. One of its endearing features is the availability of many extensions to extend its functionality further. 

Among the safe extensions to use on Firefox is FoxyProxy. This extension simplifies the process of configuring your browser to access proxy servers.

However, users are starting to complain that FoxyProxy is not working on Firefox, especially the Nightly version. This guide will show you to fix the issue easily without breaking a sweat.

Why is FoxyProxy not working?

The major reason FoxyProxy is not working on Firefox is incompatibility with your browser. The earlier versions of the extension were not compatible with some Firefox releases like Nightly.

This leads to all forms of issues while using the extension. 

Quick Tip:

If you keep having problems, try another browser. We recommend Opera browser because it has a free, built-in VPN that can help you hide your IP and change virtual location.

It gives you access to several locations around the world, and the traffic data is unlimited. You can enable/disable it in just one click.


Use Opera’s VPN as an up-to-date and unlimited alternative to FoxyProxy!
