Re: URL spoofing bug involving Firefox's error pages and document.write



Great!

We should fill up %20 as many as  possible to hide the payloads in
some wider screens.

The JavaScript Test 2 example is great for stealth phishing attacks
while status bar spoofing is great for hiding our attack payload.

I also made a record for hiding XSS payload.
