Time Machine Restore - Now most apps can not contact internet

Hi

I just installed a new SATA drive on my older, 1.83 Ghz Mackbok Pro.
I did a Time Machine Restore of my backup to the new drive.

Now
Only Apple Safari is able to connect to the internet.
Firefox will not connect to the internet.
Itunes will not connect.
Even Mac Update is not able to connect.
Also Firefox will not quit on it's own. I have to force quit it everytime.

I am using an ethernet connection.

I tried starting from the installation disk and Repairing
Permissions and Repairing Disk.
Everything checks out ok.

Were you using Little Snitch? Is the firewall on?

so nothing about your actual internet connection changed? (ISP, router, etc) I ask because a time machine restore assumes all the same settings as you had before, and if anything changed it could need some changes.
