Speeds up client-side countdown timers on download pages.
Waitless is a Greasemonkey/Tampermonkey userscript that speeds up JavaScript-driven countdowns on supported download pages by making browser timers appear to move faster.
It has no configuration panel and runs only on the hosts listed in the userscript header.
The current script accelerates:
setTimeoutsetIntervalDate and Date.now()performance.now() when the page allows it to be overridden500ms or more are accelerated, so short polling and animation timers stay at normal speedDefault behavior in waitless.js:
30x500ms10msdocument-startIf a page relies only on client-side JavaScript countdowns before enabling a button or showing content, this script may make that countdown finish sooner.
This does not bypass:
Some sites may also behave incorrectly if they depend on real-time timing for animations, polling, or anti-tamper logic.
Waitless script and click its install button.The current version was verified locally with a small Node-based harness that executed the userscript in a mocked browser environment.
Observed behavior:
3000ms timeout fired in about 100msDate.now() advanced about 30x faster than real elapsed timeperformance.now() advanced about 30x faster than real elapsed timeThat confirms the present implementation is working as written for timer acceleration. Real-world results still depend on how each site implements its waiting logic.
