I can access all websites except one www.facebook.com
When in command i can ping it and when i nslookup www.facebook.com i use the ip address and ping it.
But in url cannot connect to site with www or ip adres.
When i ping www.facebook.com it connect's threw local host 127.0.0.1 but with say google it connect's threw it's ip address

What can it be coz it's not the firewall

Are you trying to connect from a residential broadband line, as some places do block access to facebook (often only on company PC's though).

Also, are you connecting direct to the net or through a secondary server as a proxy?

Most likely causes:

There might be a typing error in the address.
