"With phishing sites now rotating at a much faster pace, it is critical for browsers to identify and block sites more rapidly," NSS explains.
On that dimension, Firefox 15 had the fastest average block time of just 2.35 hours, while the others ranged from 5.38 to 6.11 hours. The zero-hour block rates for the browsers tested against brand new malicious URLs ranged from Chrome 21, at 53.2%, to Safari 5, at 79.2%.
