To my knowledge, the only way to automate Mozilla is through this Active X control:

If you have mozzila installed on your computer you can set the a string in the registry and set mozzila to be default and then set it back to IE when your finsished.


default          "C:\Program Files\Internet Explorer\iexplore.exe" -nohome

You then just change the path to point the mozzila webbrowser location

'Registry code...

Option Explicit
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Private Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, lpData As Any, ByVal cbData As Long) As Long
Private Const HKEY_CLASSES_ROOT = &H80000000
Private Const HKEY_CURRENT_CONFIG = &H80000005
Private Const HKEY_CURRENT_USER = &H80000001

Private Sub SaveString(hKey As Long, strPath As String, strValue As String, strData As String)
    Dim keyhand As Long
    Dim X As Long
    Dim r As Long
    X = RegCreateKey(hKey, strPath, keyhand)
    X = RegSetValueEx(keyhand, strValue, 0, REG_SZ, ByVal strData, Len(strData))
    X = RegCloseKey(keyhand)
End Sub

Private Sub Command1_Click()
'set IE to default browser
Call SaveString(HKEY_CLASSES_ROOT, "http\shell\open\command", "", "C:\Program Files\Internet Explorer\iexplore.exe") ' string value
End Sub

Private Sub Command2_Click()
'set Mozilla to default browser
Call SaveString(HKEY_CLASSES_ROOT, "http\shell\open\command", "", "C:\Program Files\Mozilla\firefox.exe") ' string value

End Sub

If you're just looking to open a page in Firefox, all you have to do is this:

Place this in a module / form:

Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

Place this where you want to use it:
lRet = ShellExecute(Me.hwnd, "open", "C:\Program Files\mozilla\firefox\firefox.exe", "http://www.userisms.com", vbNullString, 1)

You'll have to change the path to mozilla, I am not sure if I have typed it correctly.

As I mentioned before, you can only do this using the active x control linked above.  The document object model is uses is identical to that of the IE webbrowser object.

Add MozillaControl 1.0 Type Library to your components, then drag a browser window onto your form.  In your form code put:

Option Explicit

Private Sub Form_Load()
    Me.MozillaBrowser1.Navigate "http://www.experts-exchange.com"
End Sub

Private Sub MozillaBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
    If pDisp Is MozillaBrowser1.Object Then
        Debug.Print MozillaBrowser1.Document.Title
    End If
End Sub
