I’ve found what I believe to be a bug with Firefox and I’m wondering if this actually is a bug, as well as any workarounds for this.

If you create a basic webpage with the following source:

<html>
  <head>
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.min.js"></script>
  </head>
  <body>
    <div>
      <input id="txtTest" type="text" />
      <input type="button" onclick="$('#txtTest').attr('disabled','disabled');" value="Set Disabled (jQuery)" />
      <input type="button" onclick="document.getElementById('txtTest').disabled = true;" value="Set Disabled (js)" />
      <input type="button" onclick="$('#txtTest').removeAttr('disabled');" value="Remove Disabled" />
    </div>
  </body>
</html>

If you disable the textbox dynamically and then refresh the page, the textbox will remain disabled instead of resetting back to its original state of not disabled. I’ve tried this in IE8 and Chrome and those behave as I would expect, resetting the textbox back to not disabled when I refresh.

Another interesting bit of information is that it still does the same thing if the input is a checkbox instead of a textbox.

    This is a “feature” of Firefox which remembers form input values across page refreshes. To fix this behavior, you simply set autocomplete="off" on the form containing the inputs, or just directly to the input.

    This stops autocomplete from working and prevents the browser from remembering the state of input fields.

    Alternatively, you can just “hard-refresh” by clicking CTRL+F5. This will completely reset the current page.
