I used to have that problem. If the game is very lagging, you can fix that by closing your browser every once and a while. It lags if you keep the game open for too long. That's about the best explanation I can give for that.

As for the black screen, try scrolling the page up and down. That should make the game re-appear. It used to happen to me whenever I would complete a mission. It doesn't now, though, for some reason. It could've been a bug that got fixed, though. Or just my internet connection.
