  4. // @description:ru На порядок ускоряет время загрузки страниц с большим количеством вставленных Youtube-видео. С первого момента загрузки страницы появляются заглушки для видео, которые можно щелкнуть для загрузки плеера, и почти сразу же появляются кавер-картинки с названием видео. В опциях можно включить режим использования упрощенного браузерного плеера (макс. 720p).
