JS Toggle

About

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.

◉ 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. This is the same mechanism Chrome uses internally — reliable, fast, and no hacks.

▸ Context menu: Right-click any page → Toggle, Enable, or Disable JS
▸ Global: One toggle blocks JS on every site across all windows
▸ Reset: Re-enables JS everywhere using per-domain rules that override other extensions
