For an example, I have this
yt-player-quality value for www.youtube.com domain in my firefox local-storage which saves the visitor's youtube player quality.
The value has set to:
which means next time I play a youtube video, it loads with quality 360p
(possible values are:
I want to freeze it's value to
large in my browser. So even If I delete my browser data, It always load the quality 480p.
I don't like always logged in to youtube.com. I always clean cookies and data.
