Facebook like plugin wizard - the like button unclick itself

问题

after creating a fun-page on facebook, I want to generate the 'like' plugin button (http://developers.facebook.com/docs/reference/plugins/like/), but when I test it (the click action) in the wizard, I see the 'error' label (after click I see that my page was not found). Any ideas why it happens ?

edit:

in the firefox's error console, I receive the error:

Error: Uncaught exception: Error: Site http://www.facebook.com not been granted permission to read properties Proxy.InstallTrigger
