Also, iTunes can't connect to the iTunes store.

Are you still connected to your wifi or ethernet connection and have you tried to renew dhcp?

Yeah, done all that, rebooted etc. Firefox can still go online. So it just some stupid setting I accidentally changed or something.

I can't update the software via apple, software update either. So much be a system thing?

There's no "going online" with Safari. If you have a network connection, it works.

If you're getting a "not found" error, the browser is connecting to the remote host, and just isn't finding whatever it is you're looking for.

Almost smells like a DNS issue either with your machine or your ISP, but I can't say for sure without some more information.

I found " Web Proxy " had been checked in the network preferences, i unchecked it and now it works. No idea what a web proxy is or why i would have checked it.
