publishes problem

Gud day!

i currently doing my flash document,the concept was if the button will click there will be a open new tab and the website will appear(hyperlink button) but when i publish it, there's an error appearing on my screen said " adobe flash player has stopped a potentially unsafe operation. the ff local aplication on your computer or network blah.. blah:

my code was:
mybutton.onRelease = function(){
getURL("http://www.completethecircuit.com/?page_id=17", "_self");
}

and then i found out on the internet that the flash has a problem when it plays to firefox, there is a code given on that forum, and then i changed my code to :

var swfUrl:String = _root._url;
var lastSlashIndex:Number = swfUrl.lastIndexOf("/");
var pipeIndex:Number = swfUrl.indexOf("|");
var baseUrl:String;
if (pipeIndex >= 0)
{
baseUrl = swfUrl.substring(0, pipeIndex);
baseUrl += ":";
}
else
{
baseUrl = "";
}
baseUrl += swfUrl.substring(pipeIndex + 1, lastSlashIndex + 1);

btn_About.onRelease = function()
{
var targetUrl:String = baseUrl + "http://www.completethecircuit.com/?page_id=17";
getURL(targetUrl, "_blank");
};

but when i published and test the movie, the error appear on my screen was:
"Firefox can't find the file at /C:/Documents and Settings/F3/Desktop/http://www.completethecircuit.com/?page_id=17."...


any solution to my problem??
thanks in advance! :)
