Now check out security firm Secunia’s pages on Known Firefox 1.x vulnerabilities and known IE 6.x vulnerabilities. Compare the number, severity and age of still-unpatched vulnerabilities. There are 2-year-old vulnerabilities in IE that have never been fixed!
This may help explain the “double standard” Photomatt and others see in the way many people react to security flaws found in the two browsers. If nothing else, Mozilla is perceived as having a faster reaction time and, overall, a better track record. So it’s a matter of “Eh, they’ll fix it in a few days,” vs. “My God, man, not another one!”
