YouTube Windowed Fullscreen

Maximize YouTube videos to fill the browser window without triggering OS-level fullscreen.

YouTube Windowed Fullscreen lets you maximize YouTube videos to fill your entire browser window or tab without triggering OS-level fullscreen. Enjoy the immersive feel of full-screen video while keeping your browser tabs, bookmarks bar, and OS desktop panels fully accessible. Perfect for multitasking on wide monitors and tiling window managers (Hyprland, i3, Sway).
