Recently my Firefox has been sending/downloading data from these IPs: 209.197.3.20 192.229.237.98 A quick google search of these IPs reveal that they are from - Highwinds Network Group - EdgeCast Networks It connects to these IPs even though I am not doing anything on Firefox, and hogging my bandwidth. Am I missing something? Is this built in Firefox function or do you guys think I am hosting a malware or something?
