FoxyProxy leaks DNS lookups

FoxyProxy think a good proxy manager, but I'm not recommending its use. Here's why: It is leaking all DNS requests even with the field "Use SOCKS proxy for DNS lookups" enabled. I did the test setting HTTP proxies and SOCKS proxies, in both cases the result was disappointing, all DNS lookups were captured by the sniffer and were exposed on the network. The DNS request doesn't pass through proxy server.

The solution to the problem is simple, don't use FoxyProxy, configure your proxy settings by direct connection settings in Firefox. In this way, the DNS has not leaked according to my tests.

Tests done in Firefox last version (3.5.3) and FoxyProxy version 2.14.
