A fix for the recent TURKTRUST certificate kerfuffle is included in the update, as Firefox has removed the company’s most recent root certificate from its code and marked two other intermediate certificates previously issued by the Turkish authority as untrusted. A post by Michael Coates, Firefox’s Director of Security Assurance on the company’s Security Blog last week notes that TURKTRUST’s new certificate had been included in the Firefox 18 beta but has since been suspended.

According to a post on Mozilla’s blog yesterday, Firefox 18 also boasts a new phishing and malware protection component. Now the browser will warn users when they stumble upon sites that may be spreading malware or trying tFirefoxo phish users.
