Does anyone know when FF will have full IDN support?

The first IDN ccTLD is now available.
http://blog.icann.org/2010/05/idn-cctlds/

I have tried FF 3.6.3 and Chromium 5.6.396.0 (46380). They both
displayed this

<http://xn--4gbrim.xn----rmckbbajlc6dj7bxne2c.xn--wgbh1c/ar/default.aspx>

instead of this

<http://وزارة-الأتصالات.مصر>

TIA

Best asked at the Moz developers group...
or maybe Herb might have an idea...

Three things which you need to be aware of

1. If you want to see the above as an IDN instead of as punycode,
simply add the following to your Firefox about:config

network.IDN.whitelist.xn--wgbh1c boolean true

2. To prevent IDN homograph attacks, Firefox displays IDNs for
some TLDs and not for others. Firefox contains a whitelist
of TLDs which have a domain registration policy which prevents
IDN homograph attacks. See
http://www.mozilla.org/projects/security/tld-idn-policy-list.html

3. I trust that you know what an IDN homograph attack is.
If not, read this:
http://en.wikipedia.org/wiki/IDN_homograph_attack


Just so everyone knows: The TLD مصر (xn--wgbh1c) for Egypt
went live only three days ago, on 5 May 2010.
The TLD xn--wgbh1c is not (or not yet) in Firefox's whitelist.

If the Egypt TLD registry has a published policy which prevents
IDN homograph attacks, then they should notify Mozilla and
so that their TLD will be added to the next release of Firefox.

It is unlikely that Firefox would drop all safeguards against
IDN homograph attacks. That would make Firefox vulnerable
to phishing and IDN homograph attacks.

Ralph, that is pretty interesting - thanks. And I thought calculus was
hard...

The first IDN ccTLDs officially went live on 5 May 2010
(Country Code Top Level Domains written in non-ascii scripts).

Here is a news article about this:
http://news.bbc.co.uk/2/hi/technology/10100108.stm
The official announcement from ICANN:
http://www.icann.org/en/announcements/announcement-05may10-en.htm

Firefox's will correctly display the IDN TLDs listed on on this page:
http://idn.icann.org/#The_example.test_names
These are test IDN TLDs which have been around for a couple of years,
and they are already in Firefox's whitelist.
