All of the links point toward:
http://pspcolls.co.uk/Firefox.htm
Googling the link just gives me a link to the actual page on Google. Links on this page go to the suspended site of:
http://firfox.bravehost.com/
If I look at the Google Cache page for this site it points to:
www.Firefox-Pro.com
They in turn link to the actual Google Toolbar download via a redirect from:
http://googlesyndication.com/
Lame :(
