QuoteMozilla on Monday released security updates for Firefox 2 and Firefox 1.5. Security updates for Firefox 1.5 will be available only until April 24, 2007, when Mozilla will stop supporting the earlier version. Mozilla is encouraging current 1.5 users to upgrade to 2.0 soon. Current users of Firefox 2.0 and 1.5 will receive an automatic update notification and will need to reload the browser for the changes to take effect. Changes in this update patch a flaw in the FTP protocol used by Firefox.
