Where's the blocked sign?

Hello.

http://videosift.com/video/Adele-James-Bond-Skyfall-Official-Video is blocked to Americans (boo!) and people already tagged it with blocked command. However, I don't see the blocked sign in my Mozilla's SeaMonkey v2.15 web browser: http://i.imgur.com/D36gI.gif ...

What's up? I can see other videos their long and NSFW signs though! Am I blind with my old compound eyes? :(

Thank you in advance. :)
