Kindle Fire

I shared my app with a friend who has a kindle fire and this was her experience:

"We wanted to try your app on the Kindle but these links don't go anywhere. It just opens a new tab that says "about:blank." I clicked the Windows link on my laptop and it was the same thing."

I told her to upload the interactplayer from the app store and she says it isn't available in the kindle app store. I don't know anything about kindles...can they access the itunes app store?

Any ideas?

Thanks
