Nice Idea
but with newer youtube UI's it doesn't work anymore, hope you can fix it

Worked once then did not work at all.

It is exactly what I'm looking for ! Just a simple way to hide YouTube controls, really helpful when I need to pause in a video in fullscreen to see all the content.

I miss just one thing to rate at 5 stars : a shortcut ! I'd love to have the same toggle system but with my keyboard, maybe the "H" key for "Hide" ? Or better, let us choose :)

But thanks, at least it works great !

i mean it does what is says on the tin; and is something i actually have needed before but never had an extension to do it
