Some proposals:
Delete IE and firefox; people could use different browsers (Chrome, Safari, Opera ...)
In the Host column, delete all source hosts (origen) because the rule shall apply to all of them anyway ("*.*").
Furthermore, as far as I know the DNS host entry in the Host column doesn't accept wildcards. Thus "*.*" and "*.hi5.com" don't work. However, DNS domain entries do accept wildcards, so take "*.hi5.com" as DNS domain. Change the facebook entry to "*.facebook.*" or "*.facebook*.*".
Good luck!
