Netflix Autoplayer - With System Sleep Timer for Chrome from www.mattevanoff.com
This is a simple extension that you install in your browser. If you don't want to do this, please see the instructions in the section below.
You can control the amount of time that the extension is allowed to run, so if you want to start with the first episode of a TV series, or you want to play for 30 seconds, you can do that.
If you want to auto-play an episode for a longer time, you can set the auto-play timer to a fixed time.
The extension allows you to turn off the autoplay timer completely, so you don't have to keep track of it.
You can easily turn off the extension, and if you want, you can turn it back on again.
