## Description

Luminous is a powerful Chrome extension designed to give you control over JavaScript code execution within your browser. Unlike other tools that block requests or enforce HTTPS, Luminous fills the gap by detecting thousands of JavaScript executions on websites and empowering you to analyze and block unwanted event collections. This extension enhances your browsing privacy and security by uncovering hidden JavaScript activities, while also serving as a valuable tool for developers seeking greater visibility into code behavior during development.

With Luminous, users gain unparalleled insight into JavaScript events, offering the freedom to decide what scripts run and helping mitigate privacy risks associated with unchecked code execution. Whether you're a privacy-conscious user or a developer refining your scripts, Luminous provides essential functionality to control and understand web-based JavaScript activities conveniently within your browser.
