joetrombone on "[Plugin: Contact Form 7] Placeholder text no longer disappears upon clicking (Firefox)"

As stated, when I click inside a field with placeholder text using Firefox, the text doesn't disappear anymore. I tested it in IE10 and the text still disappears when clicking in the field.

You can see an example of this at http://contactform7.com/setting-placeholder-text/

Is there a way to get this old functionality back in Firefox?
