Universal Video Hotkeys

About

This is the only browser extension of its kind that actually works *everywhere* because it recursively observes iframes and shadow doms and also works in cross-origin frames by message passing.

In fact, if you find any website where this extension does **not** work perfectly, please let me know! - 09/2025

- **Smart video detection**: Automatically targets the most relevant video in viewport
- **Universal shortcuts**: Works on any website with HTML5 videos, including iframes and deeply nested shadow doms
- **YouTube-compatible hotkeys**: Uses the same shortcuts you're already familiar with. Not configurable.
- **Double-click fullscreen**: Click video twice to toggle fullscreen mode
- **Native video controls**: Aggressively forces videos to show the native controls once you interact with them by hotkey. Additional controls by the website are not hidden.
- **Disable per site** if necessary
- **Lightweight**: Pure JavaScript, no dependencies, no bundling
