See also Bug 479520 as it might be related.

The issue is not adding the ß character to the .de domain, but implementing IDNA2008 in bug 479520.

As Jo says, this is a change for IDNA2008, and will be fixed when we implement that standard. Gerv

Any News about this Bug? The Bug is from 2010 and now we are in 2013 and nothing have change there. The Only Browser that manage the ß correct is Opera. The ß is Important in the German Language and Firefox is one of the Important Browser so i thing this Bug needs to be fixed and 3 Years for this are to long.
