Back to the old sidebar on YouTube door Nostrum

At the very beginning of February 2026, YouTube reduced the width of the right sidebar next to YouTube videos. YouTube Slim Sidebar reduces the width of the recommendations sidebar on the right side of YouTube videos on desktop, restoring it to how it was before 2026.

The extension helps keep the YouTube interface cleaner and less cluttered, without completely removing suggestions. Ideal for focusing on the video while keeping what matters.
