If you want those damn annotations to go away at the start of every video, this is the right script for you!
SCRIPT ONLY WORKS ON YOUTUBE WEBSITE NOT ON EMBEDDED YOUTUBE VIDEOS:
If you want no annotations on Embedded YouTube Videos, install my script: "Embedded YouTube Videos Full HD and No Annotations"
v1.4 -- Hopefully fixed annotations not being removed. Made the script only work on Youtube.com, no embedded YouTube video support anymore, see above message.
