You can disable that block in Firefox, I had the exact same issue.
Goto Tools->Options->Secuirty and un-check the "Block reported attack sites" radio button.

Yeah, I finally found that option and got through. Rather pointless having a "This isn't an attack site" link when it's going to disregard it anyway.
@ DarkOne:
Nice to see you responding so quickly to the issue.
