Theater Mode Everywhere από Tomasz Janusz

Theater Mode Everywhere maximizes any HTML5 video player to fill your entire browser window with a single keypress, giving you a clean, distraction-free cinematic experience.

Theater Mode Everywhere is built for anyone who wants to enjoy web videos without the clutter of headers, sidebars, comments, or recommendations. Whether you are watching tutorials, streams, or short clips, you can turn any video page into a cozy theater with a single keystroke.

KEY FEATURES
- One-Key Immersive Mode: Press T to instantly expand the active video to fit the browser viewport. Press it again or Escape to return to normal. If there are multiple videos on the page, press Shift+T to cycle between them.
- Sleek Custom Player Controls: A clean, modern control bar with vertical pop-up panels for volume and playback speed, glassmorphic tooltips, and remaining/elapsed time indicators.
- Volume Boost (Up to 300%): Amplify quiet video audio up to 300% using the Web Audio API, with a non-linear slider for precise adjustments and a settings toggle.
- Visual HUD Feedback: Get elegant animated overlays when adjusting volume, seeking, or toggling play/pause.
- Shadow DOM Support: Traverses and maximizes video players hidden inside modern shadow roots, improving compatibility with more websites.
- Custom Shortcuts & Settings: Configure your own keys for toggling, seeking, and frame-stepping. The in-player help overlay makes them easy to review.
- Exclusion List: Exclude specific domains via the browser toolbar popup or options page to prevent conflicts with native site layouts.

WHAT IS SUPPORTED
- Universal HTML5 Video: Works on standard HTML5 <video> elements across the web, including players encapsulated inside Shadow DOM.
- Embedded Players (iFrames): Detects and expands video elements embedded inside frames, such as YouTube or Vimeo embeds.
- Non-Standard Subtitles: Standard HTML5 subtitles (<track> tags) are supported. If a website renders subtitles through custom overlays, proprietary JavaScript, or sideloaded elements, those subtitles may not display inside the custom overlay.
- DRM-Protected Services: Some streaming platforms use DRM technologies that restrict video DOM manipulation, which may prevent the extension from scaling the video correctly.
