How to Use an IPv4 HTTP/HTTPS Proxy in Firefox

Setting up a proxy in Firefox can be really helpful if you want more privacy, want to access websites that aren't available in your area, or need it for certain tasks like web scraping. This guide will show you how to set up an IPv4 proxy step-by-step in Firefox.

‍Step 1: Open Firefox Settings

First, you need to open Firefox's settings. Open your Firefox browser, click on the three lines in the top-right corner, and select Settings. This will take you to the browser's settings page.

‍Step 2: Go to Network Settings

Scroll down the Settings page until you see Network Settings. Here, you'll see a button called Settings.... Click on this button to open the connection settings.

Step 3: Set Up the Proxy

In the Connection Settings window, you'll see different options for setting up your proxy. Choose Manual proxy configuration. Then, enter your IPv4 proxy details:

In the HTTP Proxy box, type the proxy IP address (like 193.36.x.x).
In the Port box, type the port number (like 3120).

The overall format of the proxy is IP address:Port:Username. For example, 193.36.x.x:3120:stat:proxies

IP address: This is the address of the proxy server (e.g., 193.36.x.x).
Port: This is the port number used by the proxy (e.g., 3120).
Username: This is the username required for authentication (e.g., stat).
Password: This is the password required for authentication (e.g., proxies).

If your proxy needs a username and password, Firefox will ask you for it when you try to visit a website.

Step 4: Test Your Proxy

After you've entered the proxy information, click OK to save your settings. Now you can test if your proxy works by visiting a website like https://www.whatismyip.com/ to see if your IP address has changed.
