YouTube Windowed Fullscreen

Fill your browser tab with the YouTube player. Includes a player button and a customizable keyboard shortcut.

Watch YouTube videos across your entire browser tab while keeping your tabs and address bar visible. Click the windowed fullscreen button next to the player's fullscreen control, or press Option + W on macOS or Alt + Shift + W on Windows. Press Esc to return to the normal page. You can also toggle the player from the extension popup. Customize, disable, or restore the keyboard shortcut in the popup. Shortcuts do not trigger while you are typing in a text field. To open a video directly in windowed fullscreen, add &startWindowedFullscreen=true to its watch URL. Privacy: the extension does not collect or sell personal data, track browsing history, or load remote code. It runs only on YouTube pages and uses Chrome storage to save and sync your shortcut preference. This is an independent extension and is not affiliated with YouTube or Google.
