I'm trying to build internet radio and add it to my toolbar,
when I try to create the component like this:

var wmp = new GeckoActiveXObject("{6BF52A52-394A-11d3-

I get the next error

Error: uncaught exception: [Exception... "Unable to create an instance
of the desired COM classCOM Error Result = 80004005" nsresult:
"0x80570039 (NS_ERROR_XPC_COM_CREATE_FAILED)" location: "JS frame ::
chrome://sampletoolbar/content/sampletoolbarRss.js :: anonymous ::
line 128" data: no]

Any help is appreciated. I know that it may concern security or other
issues but I can't seem to solve it.
Thanks very much
