Steps to set up HTTP proxy in Firefox browser

2. Here are the detailed setting steps:

Open Firefox browser

First, make sure you have installed and opened the Firefox browser. If you haven't installed it yet, you can download and install the latest version of Firefox from the [official Mozilla website](https://www.mozilla.org/firefox/new/).

Access the Settings menu

Click the three horizontal lines (menu button) in the upper right corner of the browser and select "Settings". In some versions of Firefox, this option may be called "Options" or "Preferences".

 Navigate to Network Settings

In the Settings page, scroll down to find the "Network Settings" section. Click the "Settings..." button, which will open a new window for configuring network connection settings.

Configure HTTP Proxy

In the Network Settings window that pops up, you will see several proxy configuration options:

No proxy

Use system proxy settings

Automatic proxy configuration URL

Manual proxy configuration

Select "Manual proxy configuration". Then enter your proxy server address and port number in the HTTP Proxy field. For example, if your proxy server address is `proxy.example.com` and port number is `8080`, enter these information in the corresponding fields.

 Configure other proxy options

In most cases, you only need to configure the HTTP proxy, but sometimes you may also need to set up other types of proxies, such as HTTPS proxy and FTP proxy. Enter the address and port number of these proxy servers into the corresponding fields. If you want to use the same proxy server for all protocols, you can check "Use this proxy server for all protocols".

Save settings

After entering the proxy server information, click the "OK" button to save the settings. Then close the settings page and restart the Firefox browser for the changes to take effect.
