Edge bested Chrome and Firefox by decisive margins. For instance, Chrome blocked 74% of all phishing attacks, and 88% of SEM attacks. Meanwhile, Firefox came in third in both tests, stopping just 61% of the phishing attacks and 70% of all SEM attempts... Both Chrome and Mozilla's Firefox rely on the Safe Browsing API (application programing interface), but historically, Mozilla's implementation has performed poorly compared to Google's. No shock: Google created the API. Edge also took top prize in blocking attacks from the get-go. In NSS's SEM attack testing, for example, the Microsoft browser stopped nearly every attempt from the first moments a new attack was detected. Chrome and Firefox, on the other hand, halted 75% and 54% of the brand-new attacks, respectively. Over a week's time, Chrome and Firefox improved their blocking scores, although neither reached Edge's impressive 99.8%.
The researchers spent three weeks continuously monitoring the browsers on Windows 10 computers. But in the real world, Edge runs on just 5% of all personal computers, while Firefox runs on 13% and Chrome on 60%.
