Anyone using the Firefox browser should be more than happy to hear about a security update to FF that fixes a minor quirk, which could potentially cause Denial of Service. While not a threat in the system compromise sense, it's still nice to know that the fix was rolled out so quickly. If you are using Firefox already, your browser may have let you known about the update. If not, head on over to Mozilla's site and get the 220.127.116.11 release. The problem lies within JavaScipt, and results only in a browser crash, so if you are having an issue with this I definitely suggest you get the update. You can read about the vulnerability itself here.
