## Description

**Coin Mining Blocker** is a powerful Chrome extension designed to protect your browser from unauthorized JavaScript-based cryptocurrency mining. By blocking coin mining scripts at the network level, it prevents these resource-heavy scripts from running on the webpages you visit, ensuring a smoother and safer browsing experience.

The extension features a dynamic filtering list that updates every 24 hours to identify and block new mining scripts as they emerge. Users have full control with the ability to enable or disable the network observer to allow or disallow mining scripts execution. Additionally, it conveniently displays the total count of blocked mining scripts on the current page directly in the toolbar badge, keeping you informed in real-time.

With JavaScript mining blocked by default, Coin Mining Blocker offers an effective and user-friendly solution to protect your system from unauthorized crypto mining exploits.
