Toggle Javascript

Toggle JavaScript permissions without injecting code, modifying page content, or interfering with browser behavior. The extension directly interacts with Chrome’s built-in contentSettings API, updating JavaScript permissions at the browser level without relying on external scripts, remote servers, or custom databases.

Designed for developers, security researchers, and privacy-focused users, it allows fast site debugging, testing fallback behavior without JavaScript, or blocking scripts on unfamiliar or untrusted sites. Whether speeding up browsing on slow networks or preventing unwanted tracking scripts, it offers a simple and efficient solution.

The toolbar icon dynamically reflects the JavaScript status of the active site, ensuring clear visual feedback. The extension requires only minimal permissions (tabs and contentSettings), does not run any persistent background scripts, and has an extremely small memory and CPU footprint. It operates fully offline and never logs, tracks, or analyzes user behavior.

Built for simplicity, privacy, and speed, this tool provides granular JavaScript control per domain without altering global settings, ensuring Chrome’s native performance is preserved.
