User Reviews
Incredibly fun addon, only issues are the danmaku not being smooth and comments with multiple timestamps showing multiple times, so if one comment has the timestamp "0:39" copy and pasted 20 times in their comment, the comment shows up 20 times

Does what it said on the hood, it scrolls the comments that contain timestamps on the video niconico style.
My only real issue with it is the low (or at least, mismatched from the video) framerate of the scrolling comments as they tend to pull my eyes away from the video, but that's more of a me problem.

Is niconico-yt Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
niconico-yt requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
