Très pratique, les mises à jours sont très rapides, à conseiller.
Mais c'est comme tout produit, il faut faire des tests pour connaitre son utilisation.

best thing ever

Fixed the layout issue manually using Stylus plugin and adding

#columns.ytd-watch-flexy {margin-top: 200px !important;}

While the plug-in gets fixed, you can run this JS manually by adding it to the custom script at the bottom of the plug-in's option page:

document.getElementById("full-bleed-container").setAttribute("style","z-index: 1000;position:absolute");

The custom script icon won't be accessible because of the items to overlay the video controls, so you'll want to turn off the option to automatically expand video.

Thank you for the Update.

Normally a good extention, but fully broken as of right now. I guess youtube updated their siute yet again with no reason...

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?

cinema mode no longer functions

all good

Fantastica fuonziona per tante cose mi piace che cambia il colore a youtupe e aumenta il volume

Honestly, this makes browsing and watching Youtube videos immeasurably better than the vanilla experience. Changing color themes, making videos expand to fit the screen space, adding more controls, and giving the option to disable Youtube Chat are all immensely useful.

Also, the developer seems to be pretty quick with fixes. While the version that is current while I'm writing this (2.0.119.2) was broken one to two days ago thanks to a Youtube update, the dev has a post on his site stating the new version has been submitted and is awaiting approval.
