It works well, however it has a huge drawback. Links with timestamps don't work. When hitting play it starts from the beginning.

Эх блин, не всё работает, очень жаль. Видео хоть и не воспроизводится автоматически, но буферизуется. Также не работает автопауза при смене вкладки. Это же расширение для Google Chrome останавливает буферизацию, хотя настройки одинаковые.

conflict with you tube ADULT VIDEOS

Great!

Sometimes is does not work.
I found another addon which always works:
Autoplay No More
by Kiko

Works as intended. Simple as that.

Work just like on chrome. bravo

Не то что нужно. Как можно увидеть превьюшку перед видео? Каким расширением? В браузере на полный экран его видно какие-то доли секунды, потом идет воспроизведение, а это расширение лишь останавливает уже начатое воспроизведение, да и то, не всегда

This is my first ever review of ANYTHING. THIS DOES NOT WORK. DON'T DOWNLOAD. WASTE OF DATA AND , WORSE, TIME

Thank You So Much Dear "James Fray" , For This Brilliant addon , But , This addon have two problem , 1. when ,open a new youtube video , by click on it , this addon doesn,t work . and 2. when open many youtube video , in a new tabs , but , dont go in video tabs , this addon doesn,t work .

It does indeed stop autoplay and pre-loading and at first appears to be an excellent solution, but unfortunately it also interferes with YouTube's ad system in such a way that the ad cycles in a loop and the video never starts. That makes it unusable for me. I tested this in Firefox 65.0.2 on Windows7-64.

Перестало работать в Youtube. Отключил, удалил. Поставил заново. Все отлично!

It didn't work - I opened one video page and it started playing immediately. I put it on pause and the load bar continued moving, so even on pause it was still loading. I have a data limit on my connection; auto-play is NOT an option for me. (This is my first attempt to use an up-to-date version of Firefox, and I've had to change almost all of my addons. If I can't find something to stop YT - or any - videos from auto-playing I'll be abandoning this version and going back to the one that works.)
