Short description: Precise speed control for videos, games, and animations in your browser: 0.1x-100x, auto-apply, and support for complex web scenarios. Full description: SpeedMaster Pro is a universal browser time controller. Speed up or slow down videos, browser games, and animations with precise control from 0.1x to 100x, including fractional values. What the extension can do: • Flexible 0.1x-100x speed range with fine control. • Video and audio control via playbackRate. • Auto-apply to newly added elements on the page. • Game-loop acceleration: requestAnimationFrame and time sources (performance.now / Date.now). • setTimeout / setInterval timer scaling. • CSS and Web Animations API animation acceleration. • Works in nested iframes and dynamically loaded content. Important: Some players and websites may limit maximum speed (often around 16x), so the effective range depends on the specific service. Privacy: The extension does not send your data to external servers and does not use tracking. Permissions are used only to store settings and apply speed on the active tab.
