Do you want to use proxies on your browser without affecting network traffic on your entire device? One way to do this is by using network proxy extensions like Proxy SwitchyOmega . Another option is Mozilla Firefox, which lets you configure proxy server settings directly within the app. Ready to find out how? Keep reading to see how to set up Mozilla Firefox proxy settings.

How to Set Up Mozilla Firefox Proxies

So, let’s get to it. First, you need the Firefox browser installed on your device. You can download it from here . Once ready, follow these steps to configure a proxy server on Mozilla:

1. Launch Firefox and click on the menu button (1) - the three horizontal lines on the top-right corner of the browser.
