This week, Mozilla released patches for 12 vulnerabilities in Firefox 11, the newest version of its web browser. According to a Firefox Security Advisories report, five of the eight vulnerabilities were deemed "critical," giving attackers the opportunity to run malicious code and “install software, requiring no user interaction beyond normal browsing.” While users currently have to opt in to update their browser, Mozilla reports it is in the process of adding a silent automatic patching feature to its Firefox 13 release, expected in June. The company says this will relieve “update fatigue,” experienced by users who don't keep up with the browser's security updates. While Firefox does currently offer an automatic updater, users still have to apply patches once they've downloaded the fix.
