Speed & Loop for Video од grad13

"Speed & Loop" adds simple playback speed and A-B loop controls to HTML5 videos.

• Increase or decrease speed, and even play in reverse.
• Set loop start and end points.
• Keyboard shortcuts: (S to slow, D to dash, R to reset), (A to start/end a loop, E to clear).

◻ Background & Feedback
This is a personal project, built first of all for my own daily use — it stores only its own settings (shortcuts, saved speeds by domain) in Firefox storage, and collects, transmits, or sells nothing. If something is broken for you, or almost works but not quite, I'd like to improve it. Feedback is welcome (anonymous, no account needed):
