Mozilla offers temporary fix for Firefox flaw
The problem has to do with the way the Firefox and Mozilla browsers handle International Domain Names, or IDNs. IDNs are domain names that use local language characters. The fix disables support for such Web addresses.
In addition to the downloadable fix, Mozilla on its Web site also offers instructions to manually disable IDN:
- Type “about:config” in the address bar, hit Enter
- Type “network.enableIDN” in the filter toolbar, hit Enter
- Right-click the “network.enableIDN” item and select Toggle to change value to false
