Open Firefox using a JavaScript

Question

I currently have a Java Script which Opens Internet Explorer with a specific website. I want to change this script to open Firefox instead. Copies of the scripts are listed below:
Button programmed with;
C:\WINDOWS\system32\wscript.exe "N:\Client Folder\FF_clientscript.js"
which calls;
var navOpenInBackgroundTab = 0x1000;
var oIE = new ActiveXObject("InternetExplorer.Application");
oIE.Navigate2("http://www.client_website/");
oIE.Visible = true;
So far I haven't been able to find anything similar for Firefox. Can anyone assist?

Executing this code from the JS console will change the font size of all the Measurement annotations to 20. You can change the value in the first line to use a different font size:
var newTextSize = 20;
this.syncAnnotScan();
var annots = this.getAnnots();
for (var i in annots) {
    var annot = annots[i];
    if (annots[i].type=="Line") {
        var richText = annot.richContents;
        for (var i in richText) {
            richText[i].textSize = newTextSize;
        annot.richContents = richText;
