Google Chrome Blocks Over 7 Billion Unwanted Notifications Daily on Android

Google reported that its Chrome protection systems blocked more than 7 billion unwanted notifications every day on Android during the first quarter of 2026. Websites increasingly use browser notifications to deliver phishing attempts, fraudulent payment requests, and malware. Chrome applies a multi-layer "Swiss cheese" defense model where several overlapping filters compensate for each other's weaknesses. The browser automatically revokes notification permissions from sites that have not been visited recently or that trigger repeated security warnings, and it can also cancel associated subscriptions. For particularly noisy resources, Chrome enforces a hard limit of 1,000 messages per minute and returns HTTP 429 responses to excess traffic. Google also made permission prompts less intrusive on Android, which reduced background activity and improved battery life. Users can review and manage notification permissions through Safety Hub on both desktop and mobile versions of Chrome.
