On September 6 a security vulnerability affecting all versions of Mozilla Firefox and the Mozilla Suite was reported to Mozilla by Tom Ferris and on September 8th was publicly disclosed.
On September 9, the Mozilla team released a configuration change which resolves this problem by explicitly disabling IDN in the browser. The fix is either a manual configuration change or a small download which will make this configuration change for the user. Instructions on administering these changes can be found below.
