The problem don't occur in a private window.

Firefox is set to empty cache and delete history during close.
I discovered that the extension Disable Autoplay for Youtube is the cause of this bug. When it is disabled, the problem don't happens.
I uses this extension to prevent Youtube from autoplaying the videos I watching, so I can play them manually.
