Next, I have a timer that fills 2 fields in a webbrowser, it does the following function ...

var 
  pega : string; 
begin 
  pega := Listaimportados.Items[i]; 
  I := i +1 
  nome.text := Copy(pega, 0, 10); 
  Webbrowser1.OleObject.Document.all.Item('login', 0).value := nome.text;

In this he repeats the action every 4 seconds, as you can see i + 1 jumps to the next line, which in case it is imported into listboxes (listbox).

But I have a problem, if I enter less than one item in the listbox, it starts to give error, list of bounds, how to solve?

You said in the comments that when it came to the end, you should stop the timer. Home In this case it's simple:

var 
  pega : string; 
begin 
  if I = Listaimportados.Count then
  begin
    timer1.Enabled:= False;
    Exit;
  end;
  pega := Listaimportados.Items[i]; 
  I := i +1 
  nome.text := Copy(pega, 0, 10); 
  Webbrowser1.OleObject.Document.all.Item('login', 0).value := nome.text;

In this code, I'm assuming that ListItems is an instance of a class TStringList
