The install.rdf 2.0.4 only shows a max version of 10.*. Does this addon work with FF 12.0?

I read the release info which said v13, but I was wondering about the rdf.

Questa recensione riguarda una versione precedente (2.0.4.1-signed) del componente aggiuntivo. 

Yes, it does work with FF 12.0 - I didn't update the install.rdf before upload (an oversight) but I updated addons.mozilla.org to correct this. Are you having issues installing it on FF 12?
