Instantly plays the next episode. This script skips the wait time on auto-play and circumvents the "auto pause" that checks if you're still watching.
As I'm not currently subscribed to netflix it's a tad bit difficult to fix. But after looking around a bit they probably just changed the name of one of the selectors on line 16 from '.player-postplay-still-hover-container' to 'postplay-still-container'. However since I'm not really supporting this script anymore you might want to look at this script as it seems to do what this script does and a bit more.
It works with your suggested patch ('.player-postplay-still-container'), unlike others scripts available on Greasyfork. Edit: nevermind I have to check further.
Not working anymore
Seems something changed and now it does not work. Could you check it up please?
