https://youtu.be/SeS9afnekZw Youtube Freezes when Opening Videos on Firefox. only on Firefox. this is my youtube video. i recorded this to show what it looks like. only thing that bothers me is Youtube is perfectly fine on Chrome, which i can't stand becuase of the volume of memory that Chrome uses.

i erased both of Firefox and Chrome and install only Firefox without any addons. one time i erased cookies and still same problem.

this problem only happenas after first youtube video. only the first youtube video is fine. there's no freezing, lag, latency on the first video. </blockquote>

i think this is memory usage bug. after rebooting PC and for a while youtube is fine. but after 30 mins, this bug still happens.
