Fantastic add-on that works, has useful features and simple to use.

Muda totalmente a forma de assistir vídeos. Facilita a vida, mesmo para assinantes do serviço premium do youtube.
Só uma coisa que eu sinto falta: logo no começo, nos controles do player, para cada ícone aparece um "i', que mostra uma pequena explicação do comando. Esse recurso é bem útil e não aparece nos controles de volume.

The only things missing from this extension are :
- an option to stop the really bad and forced youtube function that translates the videos titles into our youtube langage setting. Its cheat us into thinking that's a [isert your language here] video while it's in another language, and more over with a really bad translation...
- more flexibility with the overlay vide : when we scroll down, be able to move the mini video playing where we want on the screen on the fly (the current solution forces to hide a specific part of the information, either part of the comment section or the suggested videos, and you are force to find the "X" to close it or move the page at a specific height to see what you want). With such feature, we'd just have to grab and move the video , quick and clean.

great addon for youtube experience with tweaks .whole family uses

Frequent updates, developing in the right direction. Many useful features, lots of customisability.

Install it, customize it, and forget about it. You'll come to think that how you have it setup is just how Youtube is supposed to be - whether it be colors/looks or functionality. The auto-theater mode, however, is my favorite feature, followed closely by the speed controls. Never had an issue or conflict with Youtube or Firefox.

Excelente

all these features and still no subtitles

why does mozilla and its extention devs not care about accessibility for people with hearing or attention issues
