Convert code to open Firefox instead of Internet Explorer

Question

How do I change Internet Explorer to Firefox?

#include <IE.au3>
    Func _CreateIE()
        If Not IsObj($oIE) Or Not ProcessExists("iexplore.exe") Then
            $oIE = _IECreate($sURL, 0)
        EndIf
    EndFunc   ;==>_CreateIE

Answer 1

To just open the Firefox browser the following native AutoIt code suffices:

local $url="www.google.com"
$off=Run(@ProgramFilesDir & "\Mozilla Firefox\firefox.exe " & $url, "", @SW_MAXIMIZE)

For full support you'll need the user defined function FF.au3, which in turn requires the add-on mozrepl.

Don't forget to start MozRepl. FF-menu: Extras/Menu or check there "Activate on startup".

Then you can do:

#Include <FF.au3>
_FFStart([$sURL = "about:blank"[, $sProfile = "default"[, $iMode = 1[, $bHide = False[, $IP = "127.0.0.1"[, $iPort = 4242]]]]]])
