Google said its Chrome browser blocked more than 7 billion unwanted notifications daily on Android during the first quarter of 2026, as notification abuse has been increasingly used to distribute scams, malware and phishing attempts.

The company uses overlapping defense systems to catch abuse at different stages, including automatically revoking notification permissions from sites users have not recently visited and those that repeatedly trigger suspicious warnings. Chrome also limits sites classified as disruptive to 1,000 messages per minute, with excess requests returning an error, Mayank Parmar reports for BleepingComputer.
