How Manifest v3 forced us to rethink Browser Guard, and why that’s a good thing 

This article outlines how Malwarebytes Browser Guard has been reengineered for Manifest v3, shifting from complex, real-time blocking logic to a combination of static DNR rules and a new pattern- and behavior-based system that detects scams and phishing (including regex URL checks, DOM/content analysis, and favicon spoofing), with rapid rule updates every 30 minutes. It explains the constraints imposed by DNR (size limits, update cadence, simpler matching), notes differing support in Firefox and Brave, and previews integration of AI-driven Scam Guard to enhance detection capabilities.
