Netflix doesn't provide control for the playback rate in its user interface.
What should I put in the google chrome console to set the playback rate that I want?
If you want the video to go twice as fast you set it to
document.querySelector('video').playbackRate = 2
If you want half the speed you set it to
document.querySelector('video').playbackRate = 0.5
If you want the normal speed back you set it to
document.querySelector('video').playbackRate = 1
You can add this as a bookmark url so you don't need to open the console anymore, just click on the bookmark to change the speed :
javascript:(function(){document.querySelector('video').playbackRate = 2}())
javascript:(function(){document.querySelector('video').playbackRate = 0.5}())
javascript:(function(){document.querySelector('video').playbackRate = 1}())
