Replace Google CDN

Replace Google CDN with a Chinese mirror v3 > For well-known reasons, simply replacing a domain lets you continue using the public frontend libraries provided by Google. > Likewise, reference these resources with script tags to instantly speed up website access, young friend! Many websites, especially overseas ones, use Google's CDN to speed up their sites. But in China, for certain reasons, the world's fastest CDN has become the world's slowest. So I wrote this extension to replace Google's CDN with one in China. I originally used the one provided by 360. After a user pointed out that 360's did not support https, I switched to the one provided by the University of Science and Technology of China.
