Mozilla fixes "critical" bugs in new release of Firefox

Share this article:

Thirteen security vulnerabilities were fixed this week when Mozilla released Firefox 13. Four of the seven patches were deemed "critical," meaning an attacker could leverage the flaws to install malware on a user's machine without their knowledge. The critical bugs were related to buffer overflow, memory and privilege escalation issues. The new iteration of the popular browser is installed on most users' computers automatically, or will install once they restart the browser.
