FYI: Firefox users should be noticing the automatic update pretty soon - unless of course, you're really secure and not running as administrator. :-) If you are responsible for other machines, please be sure to get machines updated to this.

MozillaZine: Mozilla Firefox 1.5.0.3 Released: "Mozilla Firefox 1.5.0.3 has been released. This update fixes a publicly disclosed denial of service weakness. All users are encouraged to upgrade to this version.

The bugfixes previously planned for Firefox 1.5.0.3 were shifted to 1.5.0.4, and a quick update was released shortly after the recent 1.5.0.2 release to address the publicly reported issue. "
