In case it helps anyone out, I use Chrome normally, but for NFL season, I use Firefox (just to keep the streaming in a completely separate browser). Install an adblocker - a good one should get rid of 90% of the confusion in terms of where to click, etc.
All you need to do, is close enough ads to be able to click full screen mode, and the rest will not show up.
Quality is still a toss-up, week-to-week, but I can get the game loaded up within 2 minutes.
