How to enter proxy parameters into Firefox?
If you want to send traffic from your web browser and traffic from your browser: via a proxy, Mozilla Firefox is a great option. It uses your proxy settings at the default system scale, but you can configure separate proxy settings for Firefox only.

As a rule, you will use a proxy if your school or work provides it to you. You can also use a proxy to hide your IP address or access geoblocked websites that are not available in your country, but rather we recommend a VPN for that. If you need to configure a proxy for school or work, get the necessary identification information and read on.
Firefox is unique here because Chrome, Edge and Internet Explorer do not allow you to define a custom proxy server. They only use your system-wide proxy settings. With Firefox, you can only route web traffic via the proxy without using it for all applications of your system.
To access the proxy settings in Mozilla Firefox, click on the Firefox menu and go to Options.
Click the “Advanced” icon on the left side of the Preferences window, click on the “Network” tab at the top of the window, then click the “Parameters” button under Connection.
You can select four different proxy options here. By default, Firefox is defined on “Use the parameters of the system proxy”.
- No proxy: Firefox will not use a proxy server, even if it is configured in your proxy settings at system scale.
- Automatic detection of proxy parameters for this network: Firefox will use the automatic web proxy detection protocol, also known as WPAD, to detect the appropriate proxy for your network. This function is sometimes used only on professional and educational networks to automatically provide the proxy parameters necessary for all PCs in a network.
- Use system proxy settings: Firefox follows the proxy settings you have configured in your system settings. If you do not have a configured system scale proxy, Firefox will not use a proxy.
- Manual configuration of the proxy: Firefox allows you to manually define personalized proxy parameters that will only be used for Firefox itself.
If you select “Manual proxy configuration”, you will need to enter the settings for your proxy server in the boxes here. Your proxy service provider – or your employer, if provided by your employer – will be able to provide the parameters you need.
Enter the address of the proxy server you want to use for normal and unencrypted HTTP navigation connections in the “Proxy HTTP” box. You will also need to enter the port used by the proxy server in the “Port” area.
You will usually want to click on the “Use the proxy server for all protocols” option. Firefox will also use your HTTP proxy server for SSL encrypted HTTPS connections and FTP (File Transfer Protocol) connections.
Uncheck this box if you want to enter separate proxy servers for HTTP, HTTPS and FTP connections. It is not common.
If you configure a SOCKS proxy, leave the Proxy HTTP, Proxy SSL and Proxy FTP boxes empty. Enter the address of the SOCKS proxy in “the SOCKS host” and its port in the “Port” box.
IN RELATION :
When you host a SOCKS proxy on your local PC, you will need to enter
127.0.0.1 and the port on which the SOCKS proxy listens. For example, you will need to perform this operation if you create an SSH tunnel using dynamic port redirect and want to send your navigation traffic through it. Firefox will send your navigation activity via the proxy server running on your local computer.
By default, Firefox uses SOCKS v5 for connection. Select SOCKS v4 if your SOCKS proxy uses the old standard instead. If you are not sure, leave the option defined on SOCKS v5.
Firefox also allows you to provide a list of addresses for which it will bypass the proxy. Enter them in the “No proxy for” box. By default, the list here includes
127.0.0.1 These addresses both point to your local PC itself. When you try to access a web server running on your PC, Firefox will access it directly rather than trying to access addresses via the proxy.
You can add other domain names and IP addresses to this list. Just separate each address on the list with a comma followed by space. For example, if you want Firefox to access howtogeek.com directly instead of accessing howtogeek.com via the proxy, you should add
howtogeek.com at the end of the list like this :
localhost, 127.0.0.1, howtogeek.com
If Firefox cannot access the proxy server you are configuring – for example, if the proxy server is down, if your Internet connection is down, or if you entered the details incorrectly – you will see a “Cannot find the proxy server” error message when trying to access a website.
You will need to return to the parameters of the Firefox proxy server and deactivate the proxy or correct your proxy settings to browse the web.
