Secunia is reporting that Firefox is the most vulnerable web browser that is widely adopted on the market today.
“This year, Secunia published advisories for the four most widely used web browsers: Internet Explorer (IE), Safari, Opera, and Mozilla Firefox. 31 vulnerabilities were reported for Internet Explorer (IE 5.x, 6.x, and 7), including those publicly disclosed prior to vendor patch as well as those included in Microsoft Security Bulletins. Safari and Opera each had 32 and 30 vulnerabilities, whereas 115 vulnerabilities were registered for Firefox in 2008.”
Mozilla has chosen to respond to the findings here.
Firefox was percieved to be the most web secure browser. Looks like perceptions do vary from facts.
