Security Updates for Firefox, Opera Browsers

KrebsOnSecurity reports "Mozilla has shipped a new version of Firefox that corrects a number of vulnerabilities in the browser. ... Firefox version 3.6.4 addresses seven security holes ranging from lesser bugs to critical flaws. Mozilla says this latest version of Firefox also does a better job of handling plugin crashes, so that if a plugin causes problems when the user browses a site, Firefox will simply let the plugin crash instead of tying up the entire browser process. Firefox should auto-update (usually on your next restart of the browser), but you can force an update check by clicking “Help,” and then “Check for Updates” (when I did this, I noticed that in its place was the “Apply Downloaded Update Now,” option, indicating that Firefox had already fetched this upgrade.)"

According to Krebs, "Mozilla also shipped, 3.5.10, an update that fixes at least nine security vulnerabilities in its 3.5.x line of Firefox. The software maker will only continue to support this version of Firefox for another couple of months, so if you’re on the 3.5.x line, you might consider upgrading soon."

Krebs reports that a new version of Opera is also available that fixes at least five security flaws in the software. Opera’s update brings the browser to version 10.54. Opera is urging users to upgrade to the latest version, available here.
