THANK YOU!!!

I set network.dns.disableIPv6 to true in about:config, and now I
have a usable browser!  No more delays!

Of course, if this isn't the preferred fix, perhaps someone can
suggest a fix to my ipv6 configuration.

Not sure if the following information is needed now, but
"cat /etc/resolv.conf" yields:

  # Generated by NetworkManager
  domain hsd1.co.comcast.net.
  search hsd1.co.comcast.net.
  nameserver 68.87.85.102
  nameserver 68.87.69.150

and "grep hosts /etc/nsswitch.conf" yields:

  #hosts:     db files nisplus nis dns
  hosts:      files mdns4_minimal [NOTFOUND=return] dns

Thanks again Bob!
