Removing the autocomplete or F5 Refresh in Firefox from remembering field values…
With a normal input field, the value will be “remembered” by Firefox when you hit F5 or Refresh. ctrl-F5 will clear the value, but most users won’t know to do that. So if you need a value to remain blank, or set to it’s default value, on a regular refresh, simply add the following attribute: autocomplete="off"
That was easy.
