Block Cryptojacking with MinerBlock
Overview
MinerBlock is a browser extension designed to combat cryptojacking by actively blocking malicious cryptocurrency miners across the web. It addresses the growing threat of unauthorized mining scripts that run in users’ browsers without consent, consuming processing power and slowing down devices. The extension targets individuals and professionals who value privacy, system performance, and online security. It is particularly useful for users who frequently browse websites with embedded scripts or those concerned about digital resource exploitation.
Developed by xd4rker, MinerBlock leverages a dual-layered detection system. The first method uses a maintained blacklist to block known mining domains and scripts, a standard approach shared by many ad and tracker blockers. The second, more advanced method detects suspicious mining behavior within loaded scripts in real time, allowing it to stop inline scripts and miners operating through proxies—common evasion tactics used by malicious actors. This proactive behavior detection enhances protection beyond traditional filtering.
Real-world use cases include browsing news sites, online marketplaces, or content platforms where hidden miners may be embedded. Users benefit from reduced CPU usage, faster page load times, and improved device longevity. The extension is open-source, with its code hosted on GitHub, offering transparency and community-driven improvements. This transparency supports trust and enables independent verification of its functionality.
Key Features & Capabilities
- Multi-Stage Mining Detection – Combines blacklist filtering with real-time behavioral analysis to detect and block both known and emerging mining scripts.
- Inline Script Blocking – Stops mining scripts embedded directly in web pages, which are often missed by basic filter lists.
- Proxy and Obfuscation Resistance – Capable of identifying miners that use proxy services or obfuscation techniques to evade detection.
- Dynamic Filter Updates – Regularly updated filter list ensures protection against the latest known mining threats.
- Whitelist and Custom Filters – Allows users to exclude trusted sites or add custom rules for specific scenarios.
- Request Logging – Provides visibility into blocked mining requests, helping users monitor protection activity.
These features enable users to maintain a secure browsing environment without compromising usability. For example, a user visiting a content-heavy site with embedded scripts can rely on MinerBlock to prevent background mining without disrupting the site’s functionality. Similarly, professionals managing multiple browser tabs benefit from consistent performance and reduced CPU load. The inclusion of a settings page and user-defined filters allows for fine-tuned control, catering to both casual users and advanced privacy advocates.
User Interface, Workflow & Performance
MinerBlock features a minimal, streamlined interface that integrates seamlessly into the browser’s extension ecosystem. The UI is accessible via the browser toolbar, where a small icon indicates the extension’s active status. Clicking the icon reveals a compact dashboard showing recent blocked requests, with no complex navigation required. This simplicity ensures that users can quickly verify protection status without technical overhead.
Workflow efficiency is high, as the extension operates in the background with minimal user interaction. Once installed, it begins blocking known miners immediately. The detection logic runs silently, prioritizing system performance. No visible lag or slowdowns were reported in typical usage scenarios. However, exact performance metrics such as CPU or RAM consumption were not specified by the developer.
Stability appears consistent, with regular updates addressing bugs and improving compatibility. The changelog includes fixes for issues like false positives with minerkill.js and Cloudflare’s Rocket Loader, suggesting ongoing maintenance. The extension is designed to coexist with other browser tools, though no compatibility conflicts were documented. Overall, the user experience emphasizes reliability, transparency, and low resource impact.
Compatibility & System Requirements
MinerBlock is compatible with Windows, Mac, and Linux operating systems, making it accessible across major desktop platforms. It functions as a browser extension, meaning it requires a compatible web browser such as Chrome, Firefox, or Edge, though specific browser versions were not listed.
The installation size is 1.2 MB, indicating a lightweight footprint that does not burden system storage. This small size contributes to fast installation and minimal impact on overall system performance. The developer did not provide additional system requirements, such as minimum RAM, CPU specifications, or browser compatibility details beyond OS support.
Users should ensure their browser supports extension installation and has JavaScript enabled, as the extension relies on these features to function. Platform compatibility information is limited to the operating systems listed. No information was provided about support for mobile browsers or alternative environments.
