Where do Firefox and Chrome get their list of malware & phishing sites from?

Question

When you click on a hyperlink, Firefox and Chrome both check it against a list to see if the domain has been reported as a phishing site or a site containing malware. Where does that list come from? Do Firefox and Chrome (and maybe others) use the same list? Who manages it?

Answer 1

Firefox and Chrome use Google's Safe Browsing utility, which is managed by Google, as the name implies. They have a transparency report with statistics viewable at: http://www.google.com/transparencyreport/safebrowsing/
