Bests & Worsts Reviews from Amazon

I was forced to download this if I want to view my messages on my kindle fire and it won't even work! I use my device for convenience as there isn't always a laptop available. Now I can't read my messages at all on here. I dislike being forced to use something that is completely unnecessary. What was it costing Facebook to allow me to check my messages in my browser? I am a very satisfied consumer.
