By using "micclass", we should create Description object.
Then using For loop we count the Dialog objects, and close 
it.

can u explain it clearly plzzzzzz

By using
SystemUtil.CloseProcessByWndTitle "*.*", True

if  Browser("micClass:=Browser","index:=0").Exist(0) Then
						
Browser("micClass:=Browser","index:=0").Close


Above line of code will close all the open Browsers.

closedCount = SystemUtil.CloseProcessByName("iexplore.exe")

'Display # of closed windows
MsgBox closedCount


If you want to know more refer this link

You can use the following function. or simply 
SystemUtil.CloseProcessByName "IEXPLORE.EXE"

Public Function CloseBrowser()

    SystemUtil.CloseProcessByName "IEXPLORE.EXE"
   
End Function

Option Explicit
Dim ObjBrow,ObjName,ObjBrowName
Set ObjBrow = Description.Create()
ObjBrow(micClass).values = "Browser"
ObjName = Desktop.ChildObject(ObjBrow)
msgbox = ObjName.count
for i = 0 to  ObjName.count
	ObjBrowName = ObjName(i).getROproperty("Name")
	msgbox(ObjBrowName)
	ObjName(i).close
Next

If u are using iexplore then use this function
SystemUtil.CloseProcessByName ("iexplore.exe")

For mozilla only change the name i.e iexplore.exe
