A tiny, open-source Manifest V3 Chrome extension that does exactly one boring thing: plays generated white noise. One popup, one toggle, one volume slider. No files to download, no accounts, no tracking.
Source: github.com/jonnyjackson26/white-noise-browser-extension
What it does
- An on/off toggle to start and stop the sound.
- A volume slider (defaults to 35%).
- The noise is generated in the browser, so there are no audio files to load.
- Your on/off and volume settings are remembered between sessions.
Why it’s tiny
There’s no build step and no framework — just plain HTML, CSS, and JavaScript. The whole thing is a popup plus a small offscreen document so audio keeps playing after the popup closes.
It requests only two permissions:
storage— to save the toggle state and volume locally.offscreen— to keep audio playing once the popup is closed.
No content scripts, no remote code, no analytics, no ads, and no access to the sites you visit.
Privacy
Nothing is collected or sent anywhere — the only things stored are your on/off setting and volume, kept locally on your own device. See the full privacy policy .
