## Description

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.

## Review summary

Users report that the extension helps ultrawide YouTube viewing by filling more screen space and is a long-standing tool, with some noting smoother operation after the premium update. However, the shift to a paid model and paywall, compatibility issues with YouTube updates, privacy concerns, and workarounds to bypass payments dominate the discussion.

### Pros

- Fills more of the screen on ultrawide monitors, eliminating unused space when watching YouTube in windowed fullscreen.
- Longstanding, years-long usage; trusted by users and considered a solid tool for widescreen viewing.
- Smoother performance and additional features after the premium update, with support for ongoing development.

### Cons

- Freemium/paid model; many reviews call it scummy and say it locks features behind a paywall.
- Incompatibility with the latest YouTube player; no longer works after updates.
- Privacy concerns about tab data access and permission creep.
- Downgrading to older versions to bypass the payment indicates dissatisfaction with pricing.
