Hello! I'm developing a website and I have a Skype Call button on it. So if someone clicks it, then they can call me on Skype. It works in literally ALL browsers, except for Firefox, which simply opens Skype application and that's it. I don't know how and where to change that default FF browser's behavior? The issue is resolved. It was just a misconfiguration of Skype in FF's Options - Applications menu. Must choose Skype (default) in a drop down menu
