Add the following line, and retest in firefox to verify that the country is being passed properly:

if ($row_cust['bcountry'] != "United States"){
echo '<!-- '.$row_cust['bcountry'].' -->\n';
echo " <tr>\n";

View source, and look at the beginning of the form fields, and it will show the value of the variable. Most likely there is a difference in the way variables are passed between browsers and that is what is causing the issue.
