Is JavaScript enabled?
JavaScript powers interactive websites. If it is enabled, this page will show Yes. If not, the noscript message below still works for crawlers and locked-down browsers.
FAQ
JavaScript is a programming language that runs in your browser to make pages interactive. Most modern sites need it enabled; this tool reports whether your browser is running it.
Disabling it can improve privacy on some sites but will break many modern web apps. Most users leave it on.
- Chrome/Edge:Settings → Privacy and security → Site settings → JavaScript → Allowed / Don’t allow (or block per site).
- Firefox:about:config → javascript.enabled (true/false), or use NoScript-style extensions for per-site control.
- Safari:Settings → Security → “Enable JavaScript.”
- Reload this page afterward, if JS is off, you will see the noscript message instead of “Yes.”
