The most common reason for using proxy servers, or proxies as they are called, is anonymization. This is because they can be used to hide the user’s own IP address. Since the use of proxies allows the supposed geo-position of the user to be changed, they are often used to circumvent the blocking of websites in certain countries. However, proxies are also often used to increase speed and save bandwidth on a network so that users on the network can access the Internet quickly and easily.
HTTP/HTTPS proxy setup
Attention! Unlike Chrome, Opera, and MS Edge, the Mozilla Firefox browser has its own internal browser network settings. This means that entering proxy server data (IP address and port) into Firefox settings will only affect the operation of the browser itself. All other programs on your device will continue to work according to the network settings of your Windows or macOS operating system.
The second special feature of the Firefox browser is that it fully supports the SOCKS protocol, including its most advanced version, SOCKS5. This means that you don’t need to install any additional add-ons to work with proxy protocols in the Firefox browser without any restrictions.
Steps to set up proxies in Firefox browser
- Open the browser settings menu by clicking on the three horizontal stripes in the upper right corner of the screen and then on the menu item “Options“.
- The entire browser settings menu is displayed.
- Scroll to the “Network Settings” section on the right side of the menu and click on the “Settings…” button.
- Unlike other browsers, Mozilla Firefox can natively use proxies, i.e. without using Windows system settings.
- To configure the use of a proxy server via HTTP/HTTPS, select the item “Manual proxy configuration“. Enter the data received from the proxy provider in the “HTTP Proxy” and “Port” lines, i.e. proxy IP address and port. Then save the changes by clicking the “OK” button.
- To configure the use of a proxy server via the SOCKS protocol, select the item “Manual proxy configuration“. Enter the data received from the proxy provider in the “SOCKS Host” and “Port” fields, i.e. proxy IP address and port.
Depending on the version of the SOCKS protocol supported by your proxy server, select the item “SOCKS v4” or “SOCKS v5“. Then save the changes by clicking on the “OK” button.
Disabling proxies in Firefox
To completely disable proxies in Firefox, you must change the option field in the “Configure Proxy Access to the Internet” section to “No proxy“.
You can check if the IP changes have taken effect by going to the IP Address Discovery page.
Note that from this moment on, all connections to websites will be made from your real IP address, without the use of a proxy server.
