Loading external url probs

I can’t seem to get a link to open in a new window, no matter what I try. I thought this was a problem with firefox, but I’m not sure. I’m simply using getURL like this… the link is loaded from an XML file

mainBtn.onRelease = function():Void {

                        if (this.gallery == "yes") {
                            logo_mc.unloadMovie("MD_imagefader.swf");
                            loadGallery(this.link);
                        } else {
                            logo_mc.unloadMovie("MD_imagefader.swf");
                            mcLoader.loadMovie(this.link);
                        }
                        if (this.extlink == "yes") {
                            getURL(this.link, "_blank");
                        }
                        else {}
                
            };

Basically, firefox just says “transferring…” on the bottom when clicked forever, and never loads anything nor does it open a new window. When I test it on my local hard drive, firefox returns a security error that it’s trying to communicate with a web source.

Any ideas would be much appreciated. thanks!
