Does not work.

Set to 1080 but plays at 720.

Options never available, except you suddenly have the idea to pin this addon to a toolbar.

Tested on !"https://www.youtube.com/watch?v=tnu571p2CCw"

Ändert die Qualität vom Video zwar nicht, aber die Anzeige auf dem kleinen Zahnrad. Bringt mir nur nichts. Video bliebt 4k anstatt 1080P.

Does nothing!

Does nothing but completely ruining player's functionality. Reloading page multiple times with huge lagging, forcing back to its default "HD" even if manually attempt to select 480p and unchecked "allow player change quality once", etc.
Other products by this "developer" suffers the same disabilities. Removed all his extensions and got back browser's performance. Completely disappointing.

Keeps taking you to a vodeo that has being watched. can not get out of that page.

Completely does not work for Firefox mobile.

nem lehet letölteni a fejlesztői változathoz!

不能使用，連個鬼都沒有
