As @John pointed out, on modern browsers you can use the HTML5 valid autocomplete attribute, in your screenshot I see many textboxes, if you want to disable autocompletion on the whole form you can set this attribute directly at the form element:

<form name="form1" id="form1" method="post" autocomplete="off"
  action="http://www.example.com/form.action"&gt;
[...]
</form>

@CMS: John had it right but I wanted to apply it globally to all text input controls. Applying `autocomplete` to the form completely disabled them all as I intended. Thanks
