Comment (by someone_else):

 Replying to [comment:3 DrMikeTwiddle]:
 > Is it possible for LS to intercept queries from TB (presumably before
 they are encrypted and sent) and do a system DNS look up ??

 The socks/TCP connection(s) from Firefox to Tor are not encrypted. But
 it's a local connection and it seems unlikely that the firewall would look
 at it and do DNS queries.
