YouTube Windowed FullScreen is a lightweight Chrome extension that enables you to watch YouTube videos in fullscreen mode within your browser window, perfect for users with dual monitors or those who want to multitask without losing sight of their video. It adds a handy icon and configurable hotkey to toggle the video player to a full browser page view, maximizing screen real estate while allowing you to continue working on other tasks.

The extension offers both free and premium features. Free features include the fullscreen toggle button, configurable hotkeys, persistent search bar visibility, and video title display during fullscreen mode. Premium features, available via a one-time $12 AUD payment for lifetime access, include auto-toggle windowed fullscreen, scrolling while in fullscreen, a mini-player during scrolling, and a picture-in-picture shortcut. Recent updates have enhanced user experience by adding non-intrusive notifications on updates, scrollbar hiding options, and customization to improve thumbnail interaction. Configure the extension easily through the icon or browser settings.

User reviews

Users appreciate the add-on for enhancing YouTube viewing, especially on ultra-wide monitors and during live or archived streams. However, many are frustrated that recent updates have shifted the extension from free to subscription-based, locking previously free features behind a paywall and causing privacy concerns with new permissions. Technical problems with Firefox updates and YouTube layout changes have also been reported. Several users resort to downgrading to earlier free versions to retain functionality. Despite the issues, some users find value in the premium features and smoother performance.
