title: PHP Code working in Chrome but not Firefox
body: <pre><code>$redirect = $_GET["a"];
  
  if(isset($redirect))
  {
      $get302 = mysql_fetch_assoc(mysql_query("SELECT url, redirect from urls where redirect = '" . $redirect . "'"));
      header("Location: " . $get302["url"]);
      exit();
  }
  </code></pre>
  
  <p>As far as I know this code works fine logically. (Made sure there won't be any loops so I put an isset(). But for some reason firefox doesn't like it and I'm not sure how I can edit the code much more for it to work. </p>
  
  <p>Edit: I should also note that the code does work fine on Google Chrome.</p>
