Realmente diminui o processamento de CPU, uso de memória e rede. Dependendo da qualidade, chegou a 50% de melhora em CPU. Em rede houveram melhoras significativas, porém em memória RAM não chegou a ser muito expressivo (136 Mb).

Great! Particularly useful for long videos where you only see one person talking non-stop, with no other images, illustrations, graphs or anything useful to see.
I just stumbled on a video like that, and remembered I saw this extension. Installed it immediately.

FF 87.0 32b - works like described. Video is not downloaded at all. Nice addon. It would be good if addon could display snapshot screen likt it is before play is pressed instead of grey bar, but it is minor issue.

Невероятно! Спестява енергия, прави YouTube по приятно място и скоростта се увеличава драстично!

nice addon
