The script blocks the new YouTube Sign-in popup very neatly - however there is a problem. On several occasions the audio from the video continues to play even when you move away to another video - I think this mainly happens when you use the browsers back arrow to go back to a previous tab without stopping the video. You then end up with two audio streams (but only one video stream) playing but with no way to stop the original audio stream. Muting that tab mutes both streams. You have to close the current video tab to end the orphaned audio stream. Pretty certain this is caused by this script as it started when I installed it and seems to go away if I disable this script.
