AutoHalt од Nick Gaya

Take back control of your media viewing experience! Prevent sites from automatically playing suggested content after the content that you have selected.

AutoHalt works by scanning the website's user interface for an element such as a checkbox or button that can be clicked to disable autoplay. The extension only simulates user interactions and does not directly modify the page's content.

Supported websites: YouTube, Facebook, Hulu, Twitch, Vimeo, and Gfycat.

Functionality for each site can be enabled or disabled individually in the extension preferences in about:addons.
