I really wish this worked. It's a great idea but doesn't work, so... yeah. 3 stars for the idea, but it'd be 5 if it actually had functionality. I actually made an account just to beg you to make this work. That's saying a lot. Make it work and you'll become a millionaire :3

I never understood why Youtube allows videos to autoplay on channels. This is a very helpful script to fix this annoyance. Thanks!

Edit:
Oh, I guess I was wrong. I thought it does what it says. But obviously not working with new updated Youtube channels. For example, I tried this on Youtube channel "hotforwords" (yeah, I don't like that b*tch, but it's a good channel for testing purposes, hehe).

Mmm, I'll wait for an update ^^
