Even after closing Firefox 22.214.171.124, I've noticed that many (5 to 50) TCP connections remain in the FIN_WAIT_2 state. They do not clear out after any amount of time. I came in Monday morning and all the web pages I looked at Saturday still have TCP connections in the FIN_WAIT_2 state. Is this normal behavior?
I'm checking this by using the netstat command at the command line. I can tell that Firefox is the culprit because the connections listed are the web sites I have visited.
I only have one Firefox extension/add-on running. That's the Free Download Manager add-on.
I'm using Windows XP Home Edition SP2. I have all the latest Windows updates installed.
