Any chance to not run it on every ####ing site?

Seriously...

it doesn't technically run on every site, although the script may activate it does not apply any changes to any site that is not specifically youtube.com.
the script itself is not made for greasemonkey, it was intended for stylish and because of that, this script does not have included or excluded pages which causes it to activate on every site you visit but nothing is modified or changed and in this sense the script is technically not activated but appears as if it is in the greasemonkey drop down menu.

well finally added @include and @exclude, cause i was bored and read this and thought may as well add it

Thank you! Sorry for being so harsh about it. I have over 7k scripts installed.
Back then about 1.5k of them "did nothing"... making my browser very sluggish.
