Proxy is an intermediary part between your Computer/PC and the internet. It checks all the request made to the internet by your browser. It tries to fulfill them using its cache. Proxies are widely used to hide your PC from the internet for security, improve the performance and filter requests. They have used by the organizations, ISPs, and corporate firewalls.

  • No proxy: This option does not use any proxy for your browsing and hiding your PC from the internet.
  • Auto-detect proxy settings for this network: This allows to automatically detect the proxy settings for your current network in Firefox. Firefox will use WPAD protocol (Web proxy auto-discovery protocol) to detect a specific proxy.
  • Use system proxy settings: This option will use the system configured proxy settings in your system. If you do not have set any proxy, then Firefox won’t use any proxy.

Step 3: Here we are going to use the ‘Manual proxy configuration’ to configure Firefox proxy settings:

  • Enter the proxy server address in ‘HTTP Proxy’ and port number as shown below. This will be different for every person. Below is just an example to do it.

  • Check the option ‘Use this proxy server for all protocols’ to make it the same for SSL proxy, FTP proxy and for SOCKS host. You can set manually if you want.
  • If you are setting the SOCKS proxy then you can leave the SSL proxy, HTTP proxy, FTP proxy boxes. Just enter the SOCKS proxy and its port number.
  • Firefox allows you to bypass proxy for some sites. There will be a ‘No proxy for:’ box in which you can add the sites. Just add the site name as shown below followed by space. By default, there will be the local address which means the addresses are pointing to your local PC itself.
