JS Toggle

Toggle JavaScript on/off per site with one click or right-click. Per-site control, global kill switch, smart reset. Zero tracking.

JS Toggle is a lightweight Chrome extension that lets you enable or disable JavaScript per website instantly. Designed for developers, SEO professionals, QA testers, and privacy-conscious users, it gives you precise, per-site JavaScript control without changing browser settings. ✦ Key Features ◉ One-click JavaScript enable / disable Click the extension icon and toggle JS for the current site. The page reloads automatically so changes take effect instantly. ◉ Per-site control Disable JS on one domain while keeping it enabled on others. Each site gets its own independent setting. ◉ Global kill switch Block JavaScript across every site with a single toggle. Re-enable just as easily. ◉ Right-click context menu Right-click on any page to toggle JavaScript instantly — no need to open the popup. Options include Toggle, Enable, and Disable. ◉ Smart Reset button When JS is disabled, a Reset button appears in the popup header. One click re-enables JavaScript everywhere — even overrides blocks set by other extensions or tools. ◉ Real-time sync Badge icons update instantly across all tabs to show JS status at a glance. Only shows an OFF badge when JS is disabled — no clutter when things are normal. ✦ Built For ▸ Web developers testing graceful degradation without JS ▸ SEO specialists checking how search engines see pages without JavaScript ▸ QA testers validating accessibility and non-JS fallbacks ▸ Privacy-focused users who want control over what runs in their browser ▸ Anyone who wants a fast, clean JS toggle without bloat ✦ Privacy First ◉ No tracking ◉ No ads ◉ No data collection ◉ No analytics ◉ No account required ◉ Works entirely locally using Chrome's built-in content settings API ✦ How It Works JS Toggle uses Chrome's contentSettings.javascript API to control JavaScript execution per domain.
