This is the only extension I found that adjusts brightness and volume reliably without conflicting with Dark Reader. I have no complaints about its functionality. The font can be difficult to read at larger accessibility sizes when adjusting settings, but the extension remains fully functional.

Can't believe I can actually disable playlist autoplay now. My life starts today.

J·23 Sept 2026

I love this extension, It has so much customization and does pretty much everything I would want from a YouTube extension. Been using it for a couple years. There is currently a bug with the setting "Hide Related Videos In Sidebar" where when I am signed into a YouTube account the description and comments under the video will be displayed a bit wider then the video. It ranges from slight to more noticeable. It appears to consistently scale properly if you are signed out of YouTube.
