Please update for Firefox 3.6+. You could add support for the IE-specific "urn" attribute (), though I'm hopeful to see a more comprehensive defaultURI attribute instead which could allow trying other protocols (including URNs) before falling back to "href", maybe with some scripting to allow, e.g., optionally alerting the user before redirecting them to the "href".
