Amazing addon and can not stand youtube without it but there is a small problem where recently the things under the video end up blocking some of the player if you set the player to theater mode by default. However, there is a simple fix for this by switching to default view only to re-enable theater mode again after the page has finished loading. If done correctly it should be fixed but you will have to do that with every page till the addon gets fixed. That small issue was not enough to lower the raiting tho since the dev will likley have a fix for it soon and it is not that hard to do the trick above to fix it yourself till then.

Awesome....it's the best I have no problem with this extension....I like utube video filter and control of volume level with the mouse wheel...

Layout is broken since a few days ago...

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.

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
