YouTube Window Fill

YouTube Window Fill adds a player button on YouTube watch pages that expands the video to fill your browser window without triggering browser or OS fullscreen. Use it when you want a larger, cleaner viewing experience while staying in a normal window. What it does: - Adds a window-fill button beside YouTube’s fullscreen control - Expands the player to fill the visible browser window - Hides surrounding YouTube page elements while active - Exits with one click or by pressing Escape Why use it: - Keep playback inside the browser window - Avoid fullscreen mode changes - Get a larger video view with less on-screen distraction - Stay in control while multitasking or using multiple windows How it works: - Open a YouTube watch page - Click the added window-fill button near the fullscreen button - Click again or press Escape to return to the normal page layout Notes: - Works on YouTube watch pages - Does not use browser fullscreen - May need updates if YouTube changes its page structure
