Firefox is still giving me a "Reported Attack Site" warning.
It is possible to disable these messages. However, if you go onto another site that has been hacked, and does distribute malware, you are unprotected as far as the base release Firefox goes. Other add ons or other security packages may prevent anything from getting on your system.
To turn off the "Reported Attack Site" warning, click on Edit, then Preferences, then Security. Uncheck the Block reported attack sites, and click on close.
I recommend turning the feature back on once The Planted Tank is no longer listed as an attack site.
