DNS cache is a system wide application, depending on the distribution, it's either handled by NSCd or network (Debian uses network as far as I'm aware) runing "/etc/rc.d/init.d/nscd restart" or "/etc/rc.d/init.d/network restart" should flush it. However Firefox also has it's own DNS cache for some unknown reason, it can be disabled by setting "network.dnsCacheEntries" to 0 in about:config.
