Disable YouTube Autoplay
Recently, it seems that YouTube has introduced a new type of anti-feature that consistently re-enables autoplay for videos. Even after disabling autoplay, it reverts to being enabled again within a minute, and this cycle repeats continuously. Note: this behavior occurs when you're watching a single video and is unrelated to queues or playlists.
To tackle this issue, I have developed this simple userscript. It checks every 500ms (twice a second) if autoplay is enabled, and if it is, the script promptly disables it once more. Additionally, a small counter within the autoplay toggle button displays how many times autoplay has been deactivated for the current video.
Installation
To use userscripts you need to first install a userscript manager. They come as extensions for various browsers:
After you have installed a userscript manager, head over to greasyfork.org/scripts/483523 and click on the green "Install this script" button there.
