Just updated to OSX Mavericks on my early 2011 MacBook Pro, and it's having internet connection problems. I'm using wi-fi, and so far only Firefox and Mail will connect. All other programs (such as iTunes and App Store) won't establish a connection. This is a problem that only started after I installed Mavericks. What can I do to fix this? Thanks in advance.

Make sure the Firewall is turned off in System Preferences > Security & Privacy > Firewall.
App Store / iTunes Store relies on Safari settings if you can't access secure sites from Safari then they won't work... Reset Safari and make sure Block Cookies Setting is not set to Always. You can also try to create a new user and see if it works there to help isolate the issue.
Turned off Firewall. Reset Safari, too, and put never for blocking cookies. Still no change. Even Safari isn't working. 😟
