// @name           FYTE /Fast YouTube Embedded/ Player
// @description    Hugely improves load speed of pages with lots of embedded Youtube videos by instantly showing clickable and immediately accessible placeholders, then the thumbnails are loaded in background. A fast simple HTML5 direct playback (720p max) can be selected if available for the video.
// @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).
