***Update***

I have to reset the options every time I go to YouTube. I need something that will kick in as soon I get there.

I saw somewhere that YouTube updated its platform. I hate to take away stars because it was perfect when I got it. It's just not keeping YouTube on a leash anymore. :-(

Exactly what I need! The thing I need most is to stop the video from using my data when the video loads. Thanks so much!

The only thing missing from this is support for keyboard pause/play buttons.
