This addon is great, but it won't keep subtitles on. I selected "Subtitles" under Player>Subtitles. Reinstalling it didn't fix this issue.

Nice extension, I will recommend it to my friends.

Too good!

great , I use it on firefox , edge and chrome, to be the greatest need , control volume by mouse wheel and add context menu search on youtube; if you do so; I will give 5 start from 3 accounts

Excelente trabajo

best

I recommend this extension

i like i can customize youtube ® to the next level by, for instance, allowing me to auto fullscreen once i click on a youtube ® video! - signed by: peach ⭐️ laurente

My most used Extension on Firefox, now working flawless!!! Thanky

Superb!

This add-on contains lots of bugs. First; it extends the lenght of player so if video is 16:9 it becomes much more long in player base and i have black bars on top and bottom of the video. My YT home page and YouTube users' profile pages also broken because of this add-on. They solved lots of bugs so i am just turning it off for now, i wish they can solve new issues without any more time.
Edit: "Limit Page Width" solved the bug which i mentioned (video width and home, profile pages). Thanks. But changing thumbnail quality breaks thumbnails to gray boxes.

This is really wonderful.

Good one

yes it is quite good

Amazing work that i will definitely try. I recommend all of you to use it.

It is just amazing

The best!!

Very nice extension
