## Review summary

Users praise the addon for freeing screen space by hiding UI and for letting you pop out windows and work across multiple monitors. However, Android support is often non-functional or mislabelled, behavior can be unreliable or inconsistent, updates are lacking, and Windows-specific quirks can hamper use. Overall, it’s useful for some setups but unreliable and poorly maintained.

### Pros

- Space-saving fullscreen that hides toolbars and navigation for a cleaner view.
- Supports popping out browser windows and works well on multi-monitor setups.
- Popup features and adjustable screen size reduce distractions (single-window viewing).
- Works as described for many users and keeps apps in a separate window.

### Cons

- Android support is non-existent or mislabelled, making it unusable on Android.
- Unreliable behavior; sometimes the extension does nothing or fails to exit fullscreen after playback.
- Lack of updates/maintenance appears to be a concern; not updated recently according to users.
- Windows-specific quirks (e.g., taskbar behavior) can hinder fullscreen usage.
