Background

When Mozilla’s IDN support was first being developed, the standard itself had not completely stabilized. As such, the prefix used to denote punycode-encoded strings was still changing from revision to revision. When IDN support was first checked in, the prefix was “IESG--”; now it’s “xn--” (per RFC 3490).

This preference is largely for debugging purposes.

Possible values and their effects

This string preference determines what characters denote the beginning of punycode-encoded domain names. The default value is xn--.

Caveats

  • As the IDN standard has been finalized, changing this preference will break IDN support.
