A Premium, High-Performance, Privacy-First Ad Blocker for Chromium Browsers.
Version 1.2 • Powered by ITFORSEC
AdBlockX is a professional-grade ad blocking extension built entirely on Google's strict Manifest V3 architecture. Unlike massive, legacy ad blockers that bloat your browser memory and secretly harvest telemetry, AdBlockX is engineered for raw speed, zero latency, and absolute data privacy.
- 🔄 Automatic Blocklist Updates - AdBlockX now syncs with a remote, community-maintained blocklist every 24 hours via secure CDN
- 🛡️ Enhanced Security - Strict domain validation and safety checks prevent malicious blocking rules
- ⚡ Improved Performance - Optimized YouTube ad detection with faster debounce timers
- 🎯 Custom Domain Blocking - New UI to manually add annoying ad domains on the fly
- 📊 Better Statistics - More accurate ad counting with session and lifetime tracking
- 🔒 Privacy-First Remote Updates - No telemetry, no tracking, no data collection — just safer browsing
How it works: You don't have to do anything! The moment you install AdBlockX, it uses native Chrome APIs (declarativeNetRequest) to silently sever connections to over 70+ major ad networks and tracking pixels before the browser even attempts to load them.
🆕 v1.2: Now includes automatic updates from a remote blocklist, ensuring you're always protected against the latest ad networks without manual updates.
How it works: AdBlockX automatically downloads and validates new blocking rules from our GitHub-hosted blocklist every 24 hours via the lightning-fast jsDelivr CDN.
Security features:
- ✅ Strict domain validation (only valid DNS names accepted)
- ✅ Protected allowlist (never blocks Google, GitHub, Chrome Web Store, etc.)
- ✅ Size limits (max 5,000 rules to prevent abuse)
- ✅ Content-type verification (JSON only)
- ✅ No duplicate rules
- ✅ Rate-limited to prevent bandwidth abuse
Privacy guarantee: The sync is completely anonymous. No IP logging, no tracking, no analytics. Just pure blocking rules.
How to use it: Found an annoying ad domain that slipped through?
- Click the AdBlockX shield icon in your toolbar
- Scroll to the bottom of the popup
- Type the domain (e.g.,
annoying-ads.com) into the input field - Click "Block Domain"
- Done! AdBlockX will now block all requests to that domain across all websites
Use cases:
- Block specific analytics trackers
- Block annoying pop-up domains
- Block social media trackers
- Block cryptocurrency miners
How to use it: Did a sneaky newsletter popup or an empty ad banner slip through the automated filters?
- Right-click the annoying image, video, or box
- Look at your standard Chrome context menu for two new options:
- "Block element on this site" (domain-specific)
- "Block element everywhere" (global blocking)
- Click your choice. AdBlockX instantly vaporizes the element, calculates its CSS path, and permanently remembers to hide it the next time you visit the page!
Pro tip: Use domain-specific blocking for site-specific annoyances, and global blocking for common ad containers that appear everywhere.
How to use it: Many news and sports sites now detect your ad blocker and throw up a massive wall that says "Please disable your ad blocker to read this article".
- Click the AdBlockX shield icon in your toolbar to open the popup
- Flip on the Stealth Mode switch (amber/gold color)
- Refresh the page! AdBlockX quietly injects a sophisticated payload that:
- Mocks anti-adblock detection libraries (
blockAdBlock,FuckAdBlock, etc.) - Spoofs bait element dimensions (makes hidden ads appear visible to detectors)
- Bypasses Google Funding Choices and Admiral paywalls
- Intercepts GDPR/CMP consent APIs
- Mocks anti-adblock detection libraries (
How to use it: Open the gorgeous glassmorphism popup menu anytime to see exactly how many ads have been blocked this Session and over your Lifetime.
Support your favorite creators: If you want to support a website owner or YouTube creator you love, simply click the "Whitelist this site" button. AdBlockX will instantly back down and reload the page to allow their specific ads through.
Real-time updates: Watch the counter tick up as you browse — see exactly how much cleaner your web experience has become!
How it works: YouTube is notoriously difficult to block because they constantly change their code. AdBlockX features a dedicated, highly optimized code scanner that:
- ✅ Removes video ads (pre-roll, mid-roll, post-roll)
- ✅ Skips unskippable ads automatically
- ✅ Hides sponsored video recommendations
- ✅ Removes masthead banner ads
- ✅ Blocks sidebar promotional content
- ✅ Eliminates in-feed ad units
- ✅ Fast-forwards through ad countdowns at 16x speed
- ✅ Auto-clicks "Skip Ad" buttons
- ✅ Removes overlay advertisements
🆕 v1.2 Improvements:
- Faster ad detection with optimized debounce timers (50ms vs 500ms)
- Fixed audio unmute bug after ads
- Better detection of new
#ad-badgecontainers - Improved sponsored content filtering in search results
How it works: AdBlockX automatically detects and removes annoying GDPR cookie consent banners from thousands of websites, including:
- OneTrust
- Cookiebot
- Google Funding Choices
- Sourcepoint
- Quantcast
- Generic cookie notices
Smart dismissal: AdBlockX attempts to click "Accept" buttons first, then falls back to removing the entire banner if no button is found, ensuring your consent preferences are respected when possible.
AdBlockX is distributed directly via this open-source repository so you always have the most direct, developer-signed code with no middleman.
