中国大陆的，说实话这个很好用！免费版的网速上youtube视频720p60帧完全没问题！很早都在用了，如果有人看到了请一定耐心试一试！
I'm from china,to be honest, this extension is so good that even I can watch youtube under 720p60 and cost nothing! I'v heard this extension long time ago and it's still working! If someone else see this commit please have a try with patient!
