“According to Cenzic, Firefox accounted for 44 percent of all
browser vulnerabilities reported in the first half of 2009. In
contrast, Apple’s Safari had 35 percent of all reported browser
vulnerability, Microsoft’s Internet Explorer was third at 15
percent and Opera had just six percent share.“The 2009 figures stand in contrast to Cenzic’s Q3/Q4 2008
report, where IE accounted for 43 percent of all reported Web
browser vulnerabilities and Firefox followed closely at 39
percent.“As to why Firefox’s numbers were so high, Cenzic has a few
ideas.”
