I have a big problem with the functionality in Firefox that keeps data that the user have filled in on reload F5. If i use Ctrl+F5 the forms
In case you want to keep the autocomplete feature of the browser (see other valid answers), try adding the name attribute to the form and give it a random value. It has worked for me:
<form id="my-form" name="<random-hash>">
...
</form>
I think easier and quicker way to do that is
$('input,textarea').attr('autocomplete', 'off');
