Love this extension, downloaded it on all FF browsers I have. Just few suggestions: compatibility with mobile youtube, dark mode, exception from Disable autoplay also for livestreams not just playlists. Thanks.

On FIREFOX ONLY! Volume control with the mouse wheel is just random :( Instead of following the wheel, the colume level just keeps rising for about 30 levels when wheel is moved up and vice verca for down. In effect volume control with mouse wheel is completely useless.
THe same feature works fully on my Brave browser with the Chrome extension

Very, very useful. One aspect I would like though is being able to use the modifications to videos and that they would be applied when downloading the video.

ここまで素晴らしい機能補完は見たことがない

Edit: I am now having the exact opposite problem I had in the past. The extension only seems to work in private windows now.

Amazing extension however recently I’ve noticed that it no longer works when using in a private window. The … doesn’t appear anywhere, keyboard shortcuts don’t work and it doesn’t even automatically disable autoplay anymore (the extension still does shows up in the overflow menu though). Works fine in normal windows and has many useful features so I still highly recommend.
