About SpeedMaster Pro - video and game speed booster
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.
