dear mary pass Apple ka ibook G4 hai jis mae Mac OS hai, problem ye hai k us per youtube ki videos chalti hai, per facebok(FB) per jo videos share hoi hoti hai wo us per play nai hoti, jab play karo to option ata hai k "Get flash player upgrade". pher jab upgrade per click karta hu to flash player download hota hai per wo install nai hota, mai firefox use kar raha hu.
n 2nd ye k mujhy internet download manager Mac OS k liye chahiye wo bi registered ho..

waiting for ur best repies...
