Disable Autoplay for YouTube is a lightweight Firefox addon designed to prevent YouTube videos from automatically playing, providing users with greater control over their viewing experience. The addon features a convenient toolbar button that acts as an ON/OFF switch, allowing users to easily activate or deactivate the functionality. The button's icon changes color to indicate its status, with green signifying that the addon is active and dark gray indicating it is disabled.

In addition to stopping auto-play, the addon includes customizable settings that allow users to choose whether videos should play or pause based on the tab's focus state. These options are not enabled by default, giving users the flexibility to tailor their experience. This addon is compatible with all YouTube videos, whether they are embedded or standalone, and users can opt to disable specific features through the settings page.
