Doesn't work. I don't know what other people are talking about. I have rebooted my laptop, reinstalled Firefox, disabled and re-enabled--nothing works. And all those horrific "end cards" keep blocking sometimes the most critical content of the video at the end. Nice try. Did not work.

Работает! Жаль надо вручную активировать приложение, а не автоматически срабатывает. Это просто спасение от перекрывающих контент окон в конце видео

Всё работает, нужно после установки нажать на расширения для включения, работает по факту, т.е. можно зайти на ютуб и включать/отключать не перезагружая

Amazing Add-on, does just what it says it does.
I tried 3 or 4 Add-ons earlier, that promised to hide those annoying "End-cards" on YT but they did completely unrelated, unnecessary things.
Simple & honest, this Add-on easily earned it`s 5 Stars.
(Don't forget to enable the addon in the upper right toolbar - default is "off")

Works perfect, but want a button to make it active by default.

Doesn't work

Almost perfect. But! Every time I starting the browser, I must turn on this stuff. I need a default ON switch.

Does the job perfectly. Many thanks.
