I need it.

Quick and Precise. I really love empowering browsers with this addon.

脚本管理比greasemonkey更好，兼容性也更佳

I wish I could give you guys more stars. I absolutely hated the new youtube look, so I kept selecting their revert to classic button. But then they took it away, 'bad-people', they dont care what apparently a lot of their users wanted. I found the Tampermonkey and the script to keep my old youtube layout, and it really works! Since I have no idea or understand how to even use a program such as yours. You made it simple with a few clicks and 'poof' it works! I love you guys. Please keep up the good work, keep doing what you are doing.

Thanks a ton!
