How to use proxy with Mozilla Firefox
If you want to surf the Web anonymously, you need to use a proxy server
to mask your IP address. To avoid using third-party tools, Mozilla
Firefox enables you to connect through a proxy by default. All you have
to do is change the proxy settings to use the correct Internet protocol,
or IP, address and port. The proxy IP address and port are provided by
the proxy provider. You can find hundreds of free and premium proxies
through a Google search.
In Firefox, go to Tools -> Options
Once the Firefox Options window is open, select Advanced -> Network and then click Settings
Inside the Connections Settings window, check the checkbox that says Manual proxy configuration
Or
Type the IP address of your proxy in the appropriate field. For example,
if you use a HTTP proxy, type the IP address in the HTTP Proxy field.
Type the proxy port number in the appropriate Port field, next to the proxy IP address field.
Click "OK" two times to apply and save the new proxy settings.
