Please show At least 1 place where this script works

If i understand it correctly this script should make firefox show m3u8 playback thru hls.min.js (dailymotion's development: https://github.com/dailymotion/hls.js/commits/master.atom)

But i cannot get it to work, i tried different types of CORS addons to make it work, but none of them succeeded:
https://addons.mozilla.org/en-US/firefox/addon/cors-everywhere/
https://addons.mozilla.org/en-US/firefox/addon/cors/
https://addons.mozilla.org/en-US/firefox/addon/cross-domain-cors/

Can you please give a bunch of direct links where this script works as intented for me to understand what types of media and how it should be implemented for this script to work.
Thanks!
Should be a great script, but I can't find a place where it works correctly..

Demo page: http://m.shiting5.com/tv/wlty.html Works fine with my chrome but might be very slow outside China. ps: Please paste f12-console logs and links you failed.
