What could be causing a form to not clear despite clearing the browser history in Firefox?

The form may not be clearing due to the browser cache storing the form data. To solve this issue, you can add the `autocomplete="off"` attribute to the form fields in the HTML code. This will prevent the browser from auto-filling the form data. 

<form action="submit.php" method="post">
  <input type="text" name="username" autocomplete="off">
  <input type="password" name="password" autocomplete="off">
  <input type="submit" value="Submit">
</form>
