khan academy: player

by default, khan academy uses youtube player to play its videos, but you can disable this behaviuor by doing the following:

At the end of a video’s link right after ?modal=1—, add this string: &disable_youtube=1. By doing this, YouTube will be blocked and the fallback player will be triggered. In case the video’s link ends in anything that’s not ?modal=1, add ?modal=1&disable_youtube=1 instead.
