How to stop/disable incoming TCP connections.
Hello Everyone;
I'm running Fedora 16 and an old version of Firefox/Mozilla
(this is my favorite/main computer).
I just checked my Fedora 23 box - and it does the same thing
(I've probably run Firefox once or twice for a short while
and really haven't done any surfing with it).
I've noticed, WITHIN SECONDS of bringing up Firefox, I have
a bunch of TCP connections that pop up when I do <netstat -t>.
If I shutdown Firefox, they begin to die off.
Here's a copy of a <netstat -t>
tonyp% netstat -t

Do I need to worry about this - or is it normal procedure for
browsers to connect to these places and give them information?
Can I disable/stop these connections?
