Here's a solution for you. Let me know if it worked.
1. Install the Firebug extension for Firefox. 2. Open the passport website where you're facing problems 3. Click on the green coloured tick-mark at the lower right corner. This will open the Firebug window. 4. Click on Console 5. Execute the following statement with the appropriate field name. The example given below till change the column for DD Date to 01/01/1983 : for(i=0, a=document.getElementsByTagName('input'); i<a.length; i++) {if (a[i].name=='DDDATE') {a[i].value='01/01/1983'; break;}}
