## Description

**minerBlock** is a powerful Chrome extension designed to protect users from browser-based cryptocurrency miners (cryptojacking) across the web. It employs dual methods to ensure efficient blocking: traditional blacklist-based filtering of known mining scripts and advanced detection of mining behavior within scripts to stop cryptojackers immediately. This dual approach allows minerBlock to block even inline mining scripts and those running via proxies, providing comprehensive protection for your browsing experience.

The extension is open source, with its code available on GitHub, fostering transparency and community collaboration. minerBlock is a reliable solution for users looking to enhance security and improve browser performance by preventing unauthorized mining activities.
