I have written a code for web data downloading using selenium VBA, it works good in Firefox, but many time Firefox is crashing. I tried to launch chrome/IE from vba but it's not properly happening. Below is my code....please help.

Public Sub Untitled_2()

  Dim selenium As New SeleniumWrapper.WebDriver
  Dim By As New By, Assert As New Assert, Verify As New Verify, Waiter As New    Waiter

  driver.start "firefox", "https://indexes.nasdaqomx.com/Account/LogOn"

  'below 2 line don't work
  driver.start "ie", "https://indexes.nasdaqomx.com/Account/LogOn"
  driver.start "chrome", "https://indexes.nasdaqomx.com/Account/LogOn"


  selenium.setImplicitWait 10000
  selenium.Type "css=fieldset > div.editor-field > #UserName", "xxxxxxx"
  selenium.Type "css=fieldset > div.editor-field > #Password", "xxxxxxx"
  selenium.clickAndWait "css=fieldset > p > input.button.submit"
  selenium.Click "id=menu-5"
  selenium.Click "id=menu-1"
  selenium.clickAndWait "link=U.S."
  selenium.clickAndWait "id=NDX"
  selenium.clickAndWait "link=Weighting"
  selenium.Click "id=tradeDate"
  selenium.Click "link=20"
  selenium.Select "id=timeOfDay", "label=End of Day"
  selenium.Click "id=update"
  selenium.clickAndWait "id=exportLink"

  selenium.Stop

End Sub
