Firefox not renders Google fonts (bad URI or cross-site access not allowed) someone could confirm?

Like in title, in the italian forum an user have noted that Firefox 7 
don't load Google fonts. The issue is also in nightly:

The header of this page should be use the Google font "Permanent 
Marker", before to reload the cache I see the rigth font, now I see the 
Arial font, not the Permanent Marker.

Opera renders the correct font family:

In Firefox I have this error in my console:

I have searched on Bugzilla, there exist this bug:

(FIXED) Is the case to reopen it?
