The open-source Mozilla Foundation has released a temporary fix to its Firefox browser to protect it against attackers running malicious software on users’ machines.
The downloadable fix protects users against a problem related to the way Firefox handles internationalised domain names, or IDNs.
IDNs are domain names that use local language characters. The fix disables support for such web addresses.
Mozilla said it is currently working on a permanent fix to the problem which will still permit users to use IDNs.
Mozilla issued a fix earlier this year which prevented fraudsters from using IDNs to steal cash from users via spoofed website addresses.
