BlitzLoad Chrome extension security report

## Detailed Description BlitzLoad is a high-performance browser extension that combines ad blocking, tracker prevention, and intelligent page speed optimization into a single lightweight package. ### What It Does BlitzLoad goes beyond traditional ad blockers. It blocks ads and trackers to protect your privacy, then actively optimizes how pages load so you see content faster -- especially on slower or metered connections. ### Key Features - **21,000+ Blocking Rules** -- Comprehensive coverage from EasyList, EasyPrivacy, Peter Lowe's list, uBlock Origin filters, URLhaus malware protection, and phishing defense. Ads, trackers, cryptominers, and malware domains are blocked before they ever reach your browser. - **Content Priority System** -- Automatically identifies and prioritizes critical page content (text, layout, key images) while deferring heavy non-essential resources like third-party widgets, analytics scripts, and autoplay video. - **Connection-Aware Loading** -- Detects your connection speed and adapts loading behavior accordingly. On slow or metered connections, BlitzLoad becomes more aggressive about deferring heavy resources so you get usable pages faster. - **Speculation Rules Prerendering** -- Uses the modern Speculation Rules API to intelligently prerender links you are likely to click, making navigation feel near-instant. - **Cosmetic Filtering** -- Removes ad placeholders, empty containers, and visual clutter left behind after network-level blocking. Pages look clean, not broken. - **Scriptlet Injection** -- Neutralizes anti-adblock scripts, cookie nags, and tracking workarounds using targeted scriptlet injections that run in the page context. - **Anti-Evasion Protection** -- Prevents sites from detecting that an ad blocker is active by intercepting common detection techniques at the JavaScript level. - **Cookie and Annoyance Blocking** -- Automatically dismisses cookie consent banners and removes other common page annoyances without requiring manual interaction. - **Regional Filter Support** -- Optional filter lists for China, Germany, France, Korea, Spain, and India for users who browse region-specific sites. - **Tracking Parameter Removal** -- Strips tracking parameters (UTM codes, click IDs, etc.) from URLs to prevent cross-site tracking through link decoration. ### Privacy First BlitzLoad processes everything locally on your device. There is no telemetry, no usage analytics, no data collection of any kind. Your browsing history and habits stay on your machine. Filter lists are fetched directly from their public sources and applied locally via Chrome's built-in declarativeNetRequest API.
