Thunderbird Addon Demonstrating Autocomplete With Addrbook And LDAP

This Addon creates a textbox at the end of Thunderbird main window into which you can type name and E-Mail addresses that will be autocompleted by searching the local addressbooks and the globally configured LDAP server, extra work has been done to make it with Thunderbird 2.x (Gecko 1.8) and 3.x (Gecko 1.9).

Here is a quick walkthrough:

First, in the overlay, both autocompletesearch (Gecko 1.9) and searchSessions (Gecko 1.8) are specified:

        <textbox flex="1" id="ldap-autocomp" timeout="300"
                 maxrows="4"
                 autoFill="true"
                 autoFillAfterMatch="true"
                 forceComplete="true"
                 minResultsForPopup="3"
                 ignoreBlurWhileSearching="true"
                 type="autocomplete"
                 autocompletesearch="mydomain addrbook"  
                 searchSessions="addrbook" />              

Then, in the js code, the LDAP search session gets added:

  // This function originates from setupLdapAutocompleteSession:
  // https://hg.mozilla.org/comm-central/f...oseCommands.js
  //
  // It was modified in the following ways:
  // - Modified to support both Gecko 1.8.x and 1.9+
  // - Modified to take in an array of textbox ids to which the LDAP
  //   autocomplete should be attached
  // - Removed mail.autoComplete.commentColumn support to keep code simple
  // - Removed observers on pref changes to keep code simple 

  setupLDAPAutoComplete: function(textBoxIds) {
    var autocompleteLdap = false;
    var autocompleteDirectory = null;
    autocompleteLdap = getPref("ldap_2.autoComplete.useDirectory");
 
    if (!autocompleteLdap) {
      return;
    }
    else {
      autocompleteDirectory = getPref("ldap_2.autoComplete.directoryServer");
    }
    var LDAPSession= Components.classes["@mozilla.org/autocompleteSession;1?type=ldap"];
    LDAPSession = LDAPSession.createInstance().QueryInterface(Components.interfaces.nsILDAPAutoCompleteSession);
    var url;
