Prime Speed Controller
A free Safari extension that adds A-B repeat, variable speed, and skip controls to Prime Video — handy for language study too.
Overview
Tap a start and end point to loop any scene with A-B repeat. Adjust playback from 0.5x to 5x across 15 presets, with fine-tuning down to 0.05x. Skip forward or back by 5, 10, 15, or 30 seconds. A panel tracks how much time you’ve saved by watching faster. Settings stay on-device, and nothing is sent to an external server. An independent, unofficial extension — not affiliated with Amazon or Prime Video.
