By default Firefox when using a socks proxy will still use the local DNS configuration before forwarding traffic to the proxy. This can have some drawbacks:
- Site being accessed is part of a corporate intranet or production network and the DNS records do not face the internet and are consequently not in local DNS.
- Internet censorship at the DNS level prevents use of SOCKS proxy.
Firefox can be configured to use the SOCKS proxy for DNS by changing the following setting in about:config :
Set this value to true to route DNS traffic to the SOCKS proxy.
