...ignature Firefox OS tone
brandShortName resolves to "Firefox OS". That's what Stephany said to use. But Patryk said that the user visible name should just be "Firefox". In that case you want browserBrandShortName.

Unfortunately, in unofficial builds (like we developers use all the time) we will see "Web Browser" instead of Firefox.
