If it''s designed for IE only, then I don't know what it is testing or how. I strongly suspect that it requires JavaScript, so if that script is not allowed in NoScript, then yes, you would be protected.

This tool mostly appears to be a firewall tester. My ZoneAlarm prevents Gibson's test unless I specifically allow it.
Can you find a way to reproduce the attack using Firefox?
