When we publish a website URL via Citrix, we always to lockdown the website user can access.
The easiest way is to use IE lock down mode. To enable lock down mode is simple, you only need to add “-p” parameter.
For example,

iexplorer -k http://wwww.google.com

Then when user start the application, they will get a full screen IE with no addressbar, no bottons.
But please be aware that, in lock down mode there is no exit botton, so User need to press ALT+F4 to close IE.

Is there any better option?
Yes, you can use below script:

Set objArgs = WScript.Arguments
If objArgs.Count = 0 Then
WScript.Echo "No URL provided, please supply a URL to open" & VbCrLf & VbCrLf & "e.g. CScript OpenURL.vbs http://www.google.com"
wscript.quit
End If
 
Set objIE = CreateObject("InternetExplorer.Application")
 
With CreateObject("internetexplorer.application")
   .navigate "about:blank"
   With .document.parentWindow.screen
     iHeight = .height
     iWidth = .width
   End With
End With
 
objIE.StatusBar = False
objIE.Visible = True
objIE.AddressBar = False
objIE.MenuBar = False
objIE.ToolBar = False
objIE.Top = 0
objIE.Left = 0 + 8 'Move to the side just a bit to show the desktop
objIE.Width = iWidth - 16 'Shrink to let a bit of the desktop show on the sides
objIE.Height = iHeight - 28 'Shrink a bit to see the taskbar
objIE.Navigate (objArgs(0))

Then publish “IE.vba www.google.com”
