UltraBlock Pro — Advanced Ad Blocker

About

Browse faster, safer, and without interruptions. UltraBlock Pro blocks ads, trackers, malware, and invasive scripts before they ever load — keeping your browsing clean and your data private.

🚫 AD BLOCKING Removes banner ads, video pre-rolls, pop-ups, sponsored content, and newsletter overlays across all websites. Cosmetic filtering hides empty ad containers so pages look clean, not broken.

👁 TRACKER PROTECTION Stops cross-site tracking scripts from following you around the web. Blocks third-party trackers, analytics beacons, and data collection requests in real time.

☣️ MALWARE & THREAT DEFENSE Blocks requests to known malicious domains before your browser connects. Protects against drive-by downloads, phishing redirects, and browser-based crypto miners.

🍪 COOKIE CONSENT BLOCKER Automatically dismisses cookie banners and GDPR pop-ups. No more clicking "Accept All."

▶️ AUTOPLAY BLOCKER Stops videos from auto-playing when you open a page. No unexpected audio, no wasted bandwidth.

PRO FEATURES

🕵️ STEALTH MODE — FINGERPRINT PROTECTION Most ad blockers only block network requests. UltraBlock Pro goes further. Stealth Mode protects against browser fingerprinting — the technique advertisers use to track you even without cookies.

Protected APIs: • Canvas fingerprinting — adds imperceptible noise to canvas pixel output • WebGL renderer — spoofs GPU vendor and renderer strings • Audio context — introduces subtle noise to audio processing data • Font detection — blurs font measurement results • Battery API — blocked entirely • Network Information API — returns normalized values • Tracking beacons — blocks sendBeacon calls to known tracking domains

Your privacy score is shown live in the Stealth tab.

📊 ANALYTICS DASHBOARD See exactly what UltraBlock Pro is doing with a full 30-day blocking history: • Daily bar charts of ads, trackers, and threats blocked • Hourly heatmap of your peak browsing activity • Top blocked domains • Category breakdown (ads vs. trackers vs. malware) • Export your full history as a CSV file

☁️ CLOUD SYNC Sync settings, whitelist, and custom rules across all your Chrome devices automatically. Uses Chrome's built-in sync storage — no account required, no data sent to third-party servers. Manual backup and restore also included.

🌍 ADVANCED FILTER LISTS • EasyList — the gold standard for ad blocking • EasyPrivacy — comprehensive tracker protection • Fanboy Annoyance — cookie notices, social widgets, and more • uBlock Origin Filters — community-maintained rules • Indian Ad Filter — optimized for Indian websites • YouTube Ad Filters — aggressive YouTube ad blocking • Anti-Cryptominer — blocks browser-based mining scripts • Custom Lists — add any EasyList-compatible list by URL

📱 WEBSITE REPORTS Report missed ads, broken sites, false positives, or malware directly from the extension — helping improve blocking for everyone.

CUSTOM RULES & WHITELIST Write your own blocking rules using URL patterns or regular expressions. Whitelist any domain to allow all content through.

REAL-TIME STATS Live counts for ads, trackers, and threats blocked on the current page, plus estimated data saved. A badge on the extension icon shows the block count at a glance.

PRIVACY FIRST UltraBlock Pro does not collect, transmit, or sell your browsing data. All blocking happens locally using Chrome's declarativeNetRequest API. Stats and settings stay in your browser's local storage. Cloud Sync uses Chrome's own infrastructure — your data never touches our servers.
