Me ha encantado, es super útil y tiene muchas funciones interesantes

Layout is broken since a few days ago...

Love the extension, just writing this review to report that cinema mode is broken again. I see other reports saying the same. Are updates to FF itself causing the break?

My favorite extension to configure how YouTube looks and behaves.
-1 Star because certain features don't work on a 4k display currently.

The option to disable Youtube autoplay does not work. The 'Completely stop videos instead of only preventing autoplay' option works as a stop gap, but then you have to refresh the page to get back to the previous video because the back button can't go back.
I found this extension looking for a solution to this specific problem and I did not find it, however everything else about the extension looks pretty good and I'm glad I found it regardless. -1 star for the disable autoplay not working, but if that issue is fixed I think this extension is 5 stars.

Recently, the definition setting seems to be malfunctioning. Even if the definition is set to 480p, the video still becomes 1080p.

"Convert Shorts" does not actually convert shorts until you have already navigated to the short and then refreshed the page. With this feature enabled, clicking on a short should automatically go directly to the short as a normal video. Until fixed, will have to use one of the many addons that actually provide this behavior.

Thank you for the app update. Bookmaked video does not work with the app, only when go to homepage and return does it work.
I have to click cinema mode to get full screen to edge video, is is a bug?

Can confirm what Wronschien said. Changing all values of '#player-theater-container' to '#player-wide-container' makes Cinema Mode and Auto Expand work correctly. Tested on Nightly build.

sometimes need to refresh webpage because enhances stops working after skipping some part of video(only after buffering)

it's almost perfect but i'm missing a few tools still like flipping something from portrait to landscape view etc.
Fix those things and you get a purrrrrfect 5.
