👁️ Overview

BlockForge is a next-generation browser extension that combines powerful ad blocking, comprehensive privacy protection, and advanced threat detection into a single, lightweight solution. Built on Chrome''s Manifest V3 architecture, it leverages the latest web technologies to provide maximum protection with minimal performance impact.

Unlike traditional blockers, BlockForge goes beyond simple filter lists — it actively protects you from fingerprinting, blocks malicious scripts, and uses AI-powered detection to identify emerging threats in real-time.

✨ Features

Multi-Layer Blocking System

BlockForge employs a sophisticated multi-layer approach to content blocking:

Category	Rules	Description
Ads	387	Display ads, video ads, pop-ups, banners, sponsored content
Trackers	364	Analytics scripts, tracking pixels, social widgets, cross-site trackers
Miners	10	Cryptocurrency miners, CPU-intensive scripts
Malware	2	Known malicious domains, phishing sites

Total Protection: 763 blocking rules

Uses Chrome''s native declarativeNetRequest API for maximum efficiency
No DOM manipulation overhead for basic blocking
Supports custom filter rules with multiple syntaxes
Automatic ruleset updates

AI-Powered Threat Detection

Advanced machine learning algorithms identify and block emerging threats:

Pattern Recognition: Detects new ad networks before they''re added to filter lists
Behavioral Analysis: Identifies suspicious scripts based on behavior patterns
Zero-Day Protection: Catches threats that traditional blockers miss
Continuous Learning: Improves detection accuracy over time
Heuristic Scoring: Assigns threat levels to unknown domains

Popup & Popunder Defuser

A sophisticated dual-layered system to crush synthetic and automated tabs:

Tab Lifecycle Interception: Hooks into Chrome's tabs.onUpdated event to physically close spawned tabs matching $popup or $popunder blocklist directives in milliseconds.
Synthetic Popup Blocking: Injects a MAIN world defuser that overrides window.open. It tracks physical user input (clicks/keydowns) and instantly blocks automated, non-interactive popups (like hidden data:uri redirects).

Anti-Adblock Evasion & Cosmetic Engine

Dynamic Cosmetic Filtering: Actively collapses native, programmatic ad grid containers (Taboola, Outbrain, Criteo, RevContent) via injected CSS, maintaining a flawless layout.
Bot Detection Bypass: Natively parses $ghide exemption rules to selectively disable cosmetic filtering on sites employing aggressive anti-bot/anti-adblock fingerprinting (e.g. Adscore).

Comprehensive Privacy Suite

BlockForge protects against all major fingerprinting techniques:

Protection	Method	Impact
Canvas Fingerprinting	Randomizes canvas.toDataURL() outputs	Prevents unique browser signatures
WebGL Fingerprinting	Spoofs GPU vendor/renderer info	Hides graphics hardware details
Audio Fingerprinting	Adds imperceptible noise to AudioContext	Prevents audio-based tracking
Font Fingerprinting	Randomizes font measurements	Masks installed font list
WebRTC Leak Protection	Blocks IP address exposure	Prevents real IP discovery
User-Agent Randomization	Rotates UA strings	Reduces browser uniqueness
Referrer Spoofing	Controls referrer headers	Protects browsing history
Battery API Blocking	Prevents battery status tracking	Stops battery-based fingerprinting

Advanced Analytics Dashboard

Real-time insights into your browsing protection:

Live Network Log: Watch a real-time, auto-trimming stream of every intercepted connection.
Threat Severity Engine: Trackers are instantly evaluated and categorized into Critical, High, Medium, or Low severity (e.g., Hotjar and Facebook Pixel are flagged as Critical).
Historical Trends: Charts showing blocks over time (daily, weekly, monthly)
Category Breakdown: Visual representation of threat types
Top Blocked Domains: Most frequently blocked trackers and ad networks
Bandwidth Savings: Estimate of data saved by blocking content
Privacy Score: Overall privacy protection rating
AI Detection History: Timeline of AI-detected threats

🛠️ Technical Details

Manifest V3 Architecture

BlockForge is built exclusively for Manifest V3, Chrome''s latest extension platform:

Advantages:

Better security (service workers instead of persistent background pages)
Improved performance (declarativeNetRequest API)
Enhanced privacy (limited host permissions)
Future-proof (MV2 deprecated in 2024)

Key APIs Used:

chrome.declarativeNetRequest  // Network-level blocking
chrome.storage.local          // Settings & statistics persistence
chrome.tabs                   // Tab management
chrome.webNavigation          // Navigation events
chrome.scripting              // Content script injection

DeclarativeNetRequest (DNR)

BlockForge uses Chrome''s native DNR API for maximum efficiency:

Benefits over traditional blocking:

No performance overhead (browser-native)
No need to intercept every network request
Rules evaluated in C++ (much faster than JavaScript)
Lower memory usage

Rule Types:

{
  "id": 1,
  "priority": 1,
  "action": { "type": "block" },
  "condition": {
    "urlFilter": "||ads.example.com^",
    "resourceTypes": ["script", "image", "sub_frame"]
  }
}

Privacy Protection Implementation

Canvas Fingerprinting

// Intercept canvas.toDataURL()
const originalToDataURL = HTMLCanvasElement.prototype.toDataURL;
HTMLCanvasElement.prototype.toDataURL = function() {
  // Add imperceptible random noise
  const imageData = this.getContext(''2d'').getImageData(0, 0, this.width, this.height);
  for (let i = 0; i < imageData.data.length; i += 4) {
    imageData.data[i] += Math.random() * 2 - 1;  // 1 on RGB
  }
  return originalToDataURL.apply(this, arguments);
};

WebGL Fingerprinting

// Spoof GPU information
const getParameter = WebGLRenderingContext.prototype.getParameter;
WebGLRenderingContext.prototype.getParameter = function(parameter) {
  if (parameter === 37445) return ''Generic GPU'';  // UNMASKED_VENDOR_WEBGL
  if (parameter === 37446) return ''Generic Renderer'';  // UNMASKED_RENDERER_WEBGL
  return getParameter.apply(this, arguments);
};

Storage Schema

BlockForge uses Chrome''s local storage with the following structure:

{
  "settings": {
    "blockingLevel": "moderate",  // minimal|moderate|aggressive
    "privacyProtection": {
      "canvas": true,
      "webgl": true,
      "audio": true,
      "fonts": true,
      "webrtc": true
    },
    "customRules": ["||example.com^"],
    "whitelist": ["trusted-site.com"]
  },
  "statistics": {
    "totalBlocked": 12847,
    "blockedByCategory": {
      "ads": 8234,
      "trackers": 4012,
      "miners": 15,
      "malware": 0
    },
    "blockedByDomain": {
      "ads.example.com": 234,
      "tracker.example.com": 189
    },
    "historicalData": [
      {"date": "2024-01-15", "blocks": 847}
    ]
  }
}
