We really need more information. Do you see anything in the output of "dmesg" related to your NIC (usually eth0 if there is only one)?
Is there any output in "/var/log/debug" related to the Firefox problem?
What is "Network device control"? If it is having problems, it should be logging something to one of the files in "/var/log".
