PHP contact form not working in FF but working in Edge IE chrome and safari
Question
Dear folks the following code could be perfectly executed in IE (newest), Edge, Chrome and Safari but times out in FF, also it has issues with displaying the form in firefox.
In Firefox once i press submit, it starts running the sendform.php it executes correctly, but it gets stuck once everything is filled out properly and it should send the form / email to me .
the page is also in use. Tips and tricks for better / more secure code is appreciated.
The contact from code ( as in kontakt.php):
<?php
session_start();
$success='';
if($_SESSION['sent'] == '1')
{
$success='<div class="container">
<h3>Vielen Dank. Ihre Nachricht wurde übermittelt.</h3>
</div>';
$css='<style type="text/css">#phpcontactform{display:none;}</style>';
unset($_SESSION['sent']);
}
?>

I honestly do not know what causes, the issue, could be it is only my Firefox though i doubt it. Cheers and Thanks in advance.

My guess is there are errors and Firefox is not sending a referrer so the redirect never gets sent.
Could you by any chance be sending any text that might accidentally become less than 3 characters when converted to UTF-8 or when otherwise processed?
Being able to see the contents of $err would help narrow that down or exclude that possibility.
