Goto Google. Search for ’selinux’.

You now have a Cookie from NSA.gov, and your Firefox browser has downloaded http://www.NSA.gov. Nice implementations of privacy Firefox team. Good job.

WTF? I was reading in another thread
about prefetch in the mozilla firefox family of browsers, and the more I research, the more
I reach for my tinfoil hat.

Firefox, in its default configuration, does indeed download and cache any document or page
marked for prefetch by a web page.

Code:
<!--a--><div><p class=g><!--m--><link rel="prefetch"
 href="http://www.nsa.gov/selinux/"><a class=l
 href="http://www.nsa.gov/selinux/">Security-Enhanced Linux</a>
Sure enough, the first result in a google search is marked for prefetch.
Anybody else annoyed by this?
