CleanClick od RviK

CleanClick is a privacy-first browser extension that detects and blocks malicious navigation techniques used by spam sites, ad farms, and phishing pages. It runs entirely in your browser - zero data collection, zero cloud services, zero telemetry.

Features:

• 🛡 Redirect Protection - Blocks unwanted redirects and pop-under ads triggered by clicks, hover events, or page load
• 🔍 Hidden Link Scanner - Detects invisible, off-screen, zero-opacity, and transparent overlay links that trick you into clicking
• ✅ Link Verification - Catches hover spoofing, href mutation, homograph domains (lookalike URLs), and Base tag hijacking
• 🚫 Popup Blocker - Intercepts window.open calls and closes unwanted tabs
• 📋 Clipboard Guard - Warns when sites silently modify copied content (e.g., crypto wallet address swapping)
• 🔗 URL Shortener Bypass - Previews actual destination of shortened URLs (bit.ly, tinyurl, t.co, etc.)
• 📊 Link Density Analysis - Flags pages with excessive outbound links (keyword stuffing / link farms)
• 🩺 Link Health Checker - Hover over a link to check if the destination is responsive (HEAD request)
• 🔐 Navigation Guard - Monitors form hijacking, meta refresh, Service Worker redirects, History API abuse, and postMessage navigation
• 🎭 Scam Overlay Detector - Detects fake CAPTCHAs, "Your PC is infected" scareware, and fake close buttons
• 📝 Fake Download Button Detector - Scores and flags fake download buttons on freeware/shareware sites
• 🧹 Link Sanitizer - Strips tracking parameters (utm_*, fbclid, etc.) automatically
• 🧩 Custom Rules Engine - Add your own glob/regex patterns for blocking or flagging
• 📜 Whitelist - Per-domain enable/disable with import/export
• 🌐 16 Languages - Auto-detects your browser language; switch anytime from popup or options
• 🎨 Theme Support - Auto (follows system), Light, or Dark

Privacy:
CleanClick does NOT collect, store, or transmit any personal data. All processing happens locally in your browser. No accounts. No cloud services. No analytics. No telemetry. Your browsing stays yours.
