I love Netflix. It’s a convenient and cheep way for me to watch movies and TV shows. However when I am watching TV shows all snuggled up and comfy, I don’t like to unbundle myself to click “Play Next Episode” every 20min. I wanted a way to auto play the next episode.
So I searched the internet for a fix, and I found a JavaScript Bookmarklet written by one RTPMatt on his site Mostly Worthless. In addition to handling moving between seasons, it now also adds a little text below the movie to tell you that it is on. You can click this text to change the number of episodes it will play. Entering 0 for the number of episodes will turn this off.
- Drag the link below on to your bookmarks bar.
- Start watching a TV show on Netflix.
- Click the bookmark and enter then number of episodes you want to watch.
Netflix Autoplay Bookmarklet – With Multiple Season Support!
Note: [RTPMatt has] now tested this in IE. It does NOT work. But you wouldn’t use IE anyway, would you?
If you like this, go check out RTPMatt’s site and leave him a comment. I’m sure he would appreciate the traffic.
