Its name is IdentFavIcon, worldwide Puntuado con 4 de 5 estrellas

Several localized descriptions in IdenFavIcon's install.rdf lack the line <em:name>IdentFavIcon</em:name>, which has no impact in terms of usability but only in the scope of finding the add-on in a list where its name appears as <>

Thanks for the report, I was not aware that the name should be repeated in all locales, even if it remains the same. I will fix this in the next release.
