A:Answer Don't know if you still need an answer to your question, but if you do, here goes.
The Fire TV Stick connects directly to an HDMI port on yourvTV. You don't run it through a browser. I bought it primarily to use with Amazon Prime, but I'm also using some other apos with it. Prime movies, Prime Music, Netflix, Crackle and AllCast all work great.
Plug the stick into an HDMI port, let it download any updates, and you're good to go. I have mine plugged into an HDMI port on my A/V receiver (Yamaha). Picture quality is excellent. I have a 7 channel surround system with high quality gear, so sound quality is also excellent. Overall a great device. Got mine from Best Buy on sale for $25, but even at the regular price of $40 it's still well worth the price. I'll be buying another one to use with anothet TV (although you can just remove it from one tv and connect to another).
