It looks like my proxy is really broken. When I set timeout to 30 seconds in nslookup, it still times out without receiving any response from the server.

After running Wireshark a while longer, I do finally get a matching response from the DNS server, a "server failure" (SERVFAIL?) after about 90 seconds.

I think the "multiple attempts to resolve the name" are the TCP/IP stack resending the same packet, as the DNS Transaction ID stays the same for 5 packets, I can't see an ACK, and the timings are 0, 1, 2, 4, 8, which looks like TCP/IP exponential back-off.

It would be nice if Firefox handled this better, but it's clear where the real problem lies!
