Analytic Firewall - Block tracking from GA4 од Sourabh Nagori

Analytics Firewall is a powerful, privacy-first extension designed to block intrusive tracking from the web’s most widely used analytics tools — Google Analytics 4 (GA4), Meta (Facebook) Pixel, and Microsoft Bing Analytics.

Whether you're a privacy-conscious user, web developer, or digital marketer, Analytics Firewall helps you take control of your online footprint by blocking behavioral data collection and improving your browsing speed.

🛡️ What It Blocks
Google Analytics 4 (GA4)
Blocks all outbound tracking requests to GA4 and earlier versions of Google Analytics (gtag.js, analytics.js, etc.), preventing websites from logging your behavior and events.

Meta Pixel (Facebook Pixel)
Disables tracking via fbevents.js, Meta’s powerful pixel script used across millions of websites for retargeting and analytics.

Microsoft Bing Analytics (UET Tag)
Blocks Bing's Universal Event Tracking (UET) scripts and analytics beacons used to record user behavior and ad performance.

⚙️ How It Works
Analytics Firewall runs quietly in the background, using declarative blocking rules to intercept and cancel tracking requests at the network level. It does not slow down your browser or collect any personal data.
