jkSpeed v1.0.0
Control the speed of any HTML5 video — including YouTube Shorts and videos inside iframes. Keyboard-first, with real Picture-in-Picture.
- Works on any HTML5 video — Shorts and iframe-embedded included.
- Speed presets (1×, 1.5×) and fine-tune ±0.25× nudges.
- Real Picture-in-Picture — pops the video into a native OS window, unlike YouTube's in-page miniplayer.
- Customizable keyboard shortcuts (default: S slower, D faster). Fixes AZERTY / non-US keyboards where YouTube's built-in shortcuts don't fire.
- Speed overlay, icon lights up when a video is detected.
- Opt-in: remembers your preferred speed per site (hostnames are salted + hashed, never stored in the clear).
