YouTube Dynamic Web Fullscreen

Maximize your viewing experience on YouTube with a single click.

YouTube Dynamic Web Fullscreen allows you to force the video player to fill the entire browser window without entering the traditional full-screen mode. This is perfect for multitasking with "picture-in-picture" style viewing or maximizing screen real estate on ultra-wide monitors.

Key Features:

• True Window Fill: The video resizes to fit your browser window exactly (100% width and height).
• Aspect Ratio Safe: Automatically adds black bars (letterboxing) so the video never stretches or distorts.
• Distraction Free: Instantly hides the comments, sidebar, title, and top gradient for a clean, cinema-like view.
• Smart "Always-On-Top": Uses advanced layering to ensure the video stays above all other YouTube elements.
• Zero Data Collection: This extension runs locally and collects absolutely no user data.

How to use:

• Open any YouTube video.
• Click the extension icon.
• The video will expand to fill the window.
• Click again to return to normal view.
