Re: [TWC] what could these "localhost" connections be?
said by TheWiseGuy  :Now since in this case they are established versus listening, as was the case in the other example, you may be correct, all 4 sockets/ports may be simply for pollable events. I show four lines for the Firefox sockets. Each line treats one of the endpoints as local, the other as remote. Two loopback connections have four endpoints.
I used 'netstat -ano' to get the ProcessID#. Windows Task Manager identified ProcessID# 5936 as Firefox.

Yes I understand that you need a pair of ports/sockets for one connection. I should have made it clear that I was talking about ports/sockets not connections. From the post by EG that I cited
said by a firefox programmer :
I don't know how to implement NSPR pollable events
on Windows without using a pair of TCP sockets, Now since in this case they are established versus listening, as was the case in the other example, you may be correct, all 4 sockets/ports may be simply for pollable events. Still in reading the complete reference I am not sure there should be more then 2 sockets/ports for the pollable events cited by that programmer, though it would make sense since the connection to check for a pollable event would be made to the listening socket and there normally are 2 listening ports/sockets.

Each loopback connection uses two ports, one for each end of the connection. You can see that the first two are connected to each other, as are the next two, in the OP's report. Thus the first four probably represent the two Firefox connections... |

Localhost is 127.0.0.1 and is Loopback on your computer. You can make sure that it is 127.0.0.1 by running netstat -n
»en.wikipedia.org/wiki/Localhost
It is the way a program talks to itself. Firefox uses 2 of these for Pollable events
»www2.dslreports.com/forum/remark···12761500
I am not sure how the other 2 are used but since the packets never leave your computer there should be no need to worry about connections only to Localhost.
