filtering URL or IP outogin
While using Firefox I closed all browser tabs and making sure nothing was open in Firefox. When I performed a command line, lsof -i it showed the following established by Firefox.
ec2-52-12-8-165.us-west-2.compute.amazonaws.com
ec2-34-199-87-86.compute-1.amazonaws.com
What is the best way to filtering outgoing traffic to the above sites.
