I find all my youtube in my cache folder C:\Users\Username\AppData\Local\Mozilla\Firefox\Pr ofiles\5mbx82a3.default\Cache. I just rename them in name.flv and can play them with the vlc media player. this worked fine with the sd videos but now with the hq videos I don't find 'em in this folder or it disappears as soon as it's finished. where can I find the finished HQ videos? they must be somewhere since my browser can play the videos and it's no life stream.
