But here's the thing (and I'm sure y'all are beginning to hate this refrain)
"But it works perfectly on Firefox".

Yeah, 'cause when I'm in hotels and such which have initial splash-screens
where you have to authorize before they'll pass any traffic, I can't use my
own server (and many times they won't pass any DNS traffic anyway). So in
those cases I'll grab the DNS records from their connection, which end up
in /etc/resolv.conf . It's then where the problem occurs, when the resolver
has to deal with a new source.
