Speed Up Pages

Speed up webpage timers and animation frames.

Speed Up Pages lets you speed up webpages that rely on JavaScript timers and animation frames. Use the popup to choose a speed from 1x to 100x, pause the extension on the current site, and enable or disable speed changes for setTimeout, setInterval, and requestAnimationFrame separately. The extension is useful for testing timer-heavy pages, skipping waiting periods, and quickly checking behavior that depends on browser timer APIs. It only changes JavaScript timer callbacks in pages where it is enabled. It does not speed up network requests, media playback, CSS animations, or browser-native work.
