This is not working for me in google chrome 12.
Although the script is a good space-saver on the email pages on GMail but as soon as you switch to GMail Contacts (click Contacts on left), the script causes the links to not work any more.
When the script is enabled and you go to Contacts page, all links stop working. You can't add any more contacts. After you disable the script, the Contacts page starts working again.
The author should fix this.
