download link third party source: http://apk-dl.com/files/584606824f768538382c17a1 where I got it from. Works very well. Supports Sony TV remote control to use as a mouse and store bookmarks on the front page of Puffin TV.
It apparently has native support for Flash Player. But I haven't tested that yet.
Yes! I found it while reviewing some other ATV browsers , and it was definitely my favorite!
I also had to sideload it to my Mi Box, but it works great. great mouse/pointer control compared to others, great in-built push web page from other devices, great UI.
I was in touch with the dev (who's a redditor) a couple of days ago regarding better zoom and privacy control. They seem to be on the ball.
