The DHS has had a pop at Mozilla over the MafiaaFire FireFox add-on (which isn't even theirs).
(It was a news article on Newzbin)
http://www.pcmag.com/article2/0,2817,2384983,00.aspBasically the add-on will automatically redirect FF to a sites new domain if the DHS seizes the old one.
Tbh, it's probably the best bit of publicity the add-on could ever have received.

i.e. "Visitors to Torrent-Finder.com and other sites last November, for example, were met with a notice that
the site's domain name had been shut down by the Immigration and Customs Enforcement - Homeland Security Investigations department, pursuant to a seizure warrant that would apparently be issued by a judge in the future.
..that's a pretty broad brush they have.
