Firefox does not support HTML5 Date type fields. As such, the Date of Birth field is treated as text. This means that the data inserted into the database may not be in the correct format.
Solution
Create a form of validation for these fields. Possible include a new date picker with jQuery UI just for Firefox. The format should translate to yyyy-mm-dd
This is no longer an issue as all new versions of Firefox now support HTML5 date types. For the ones that don't, Modenizer has been used to create a custom date picker with the correct format.
