Hi, Baku,
Could you help me review this patch?

The main problem is that we can't receive the "mozbrowserloadend" event. It seems that this event can't be dispatched if we enable the preload option for the "noaudio.webm". (only on the emulator-x86-kk)

However, I don't why this event can't be dispatched because I don't understand the moz-browser very well. I would open another bug to track this issue and ask kanru's feedback. In this patch, what I do is to avoid this situation happen, so I modify some logic and stop to preload the "noaudio.webm".

Very appreciate!
