# AJAX throwing JavaScript errors?

 * Hi,
 * I am having some difficulties with some WordPress files throwing a “Components
   is not defined” error in Firefox.
 * That is e.g. tw-sack.js and wp-gears.js.
 * They both try to create an ActiveXObject (for IE, I guess), which does not seem
   to work with Firefox.
 * I have posted about this here:
    [http://www.saphod.net/2008/10/17/firebug-and-the-mysterious-components-is-not-defined/](http://www.saphod.net/2008/10/17/firebug-and-the-mysterious-components-is-not-defined/)
 * Please also see the comment section.
 * Maybe someone knows the reason for the error and/or a solution?
 * Thanks!
