From the mozilla.org webpage:

"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, as a temporary measure to work around this
problem, disables IDN in the browser. IDN functionality will be
restored in a future product update. 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."
