When using firefox with proxychains -
(default configuration file with tor:
socks4 127.0.0.1 9050)
and checking on dnsleaktest.com, the original lookup returns the proxied IP, but when performing an extended search it shows the original IP/location. Does this leak occur only when using firefox ? I've tried checking the tick box: Proxy DNS when using socks v5, but that doesn't help. For example, if I were to use an application to send packets to a certain IP with proxychains, would the DNS also be leaked ? How easy would it be to trace back the default tor proxy ?
