YePpHa / YouTube Center

So, I wanna say in advance, amazing script! A must have for Greasemonkey users.

But recently, it's stopped working. I haven't done anything to cause it, it just stopped showing on the Youtube page. I went through my addons and user scripts, reinstalled Greasemonkey and ensured that the script was enabled, but nothing...

Can you help?

Firefox Version: 36.0.1
Greasemonkey Version: 2.3

greetings, Ray
