Articles on TechCrunch frequently load a mid-post JW Player alongside an additional floating Connatix video unit. Simply hiding the containers leaves the underlying media players running invisibly in the background.

Every TechCrunch article autoplays a video in the middle of the post. Hiding it isn’t enough, because the player keeps running in the background.
The video is a JW Player embed, and the page also loads Connatix’s floating ad player. Blocking their scripts stops the video from loading at all, and the cosmetic rules hide the empty box it leaves behind.
