So I want to change the user agent to this

Mozilla/5.0 (Windows NT 10.0; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0

I've tried the following

PHP Code


<?php 
Dim sUserAgent As String = "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0"
Gecko.GeckoPreferences.User("general.useragent.override") = sUserAgent 


PHP Code


<?php 
Imports System.Runtime.InteropServices

<DllImport("urlmon.dll", CharSet:=CharSet.Ansi)> _
    Private Shared Function UrlMkSetSessionOption(ByVal dwOption As Integer, ByVal pBuffer As String, ByVal dwBufferLength As Integer, ByVal dwReserved As Integer) As Integer
    End Function
    Const URLMON_OPTION_USERAGENT As Integer = &H10000001
    Public Function ChangeUserAgent(ByVal Agent As String)
        UrlMkSetSessionOption(URLMON_OPTION_USERAGENT, Agent, Agent.Length, 0)
    #End Function

ChangeUserAgent("Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A537a Safari/419.3")
 
WebBrowser1.Navigate("http://se-board.com/index.php?/index/", "_self", Nothing, "User-Agent: Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A537a Safari/419.3") 


Does Gecko no longer support user agent change anymore ? Or I'm probably doing something wrong
