Do you have a dns cache server ?
if yes, clear the cache.

dig fqdn
dig ipaddr

Do you have IPv6 enabled ?
Try to disable it and see.

Firefox:
about:config ---------> ipv6
add-on/extension blocking some traffic type, websites ? 
network config - proxy config

Do you have external (to Firefox) proxies, filters (squid, privoxy, etc)
