PHP Session not getting updated in FireFox - session

Question

I am facing a strange error. It is related to updating the php session.
I have a site whose login/logout works perfectly in chrome,safari and IE etc. But in firefox it is not working. When I login using firefox, the logout button seems to be dead or something. It just doesnt let me logout. Even if I manually type the logout link, it still doesnt do anything and keeps me logged in. I am not doing anything complex at all.
Any ideas why the same code works in chrome, IE and safari but not in firefox?
Let me know,
Thanks.
============================LOGOUT CODE===============================
public function logout() {
$this->session->unset_userdata('smallpoint_username');
$this->session->sess_destroy();
redirect(base_url() . 'forum/update_session.php?hasher = ' . time() . time() . time() . time() . time() . time() . '&&nohasher=' . time() . time() . time() . time() . time() . time() . '&&op=2', 'location', 301);
}
================SESSION SETTING CODE in LOGIN===============================
$session_array = array(
'smallpoint_username' => $insertData['username'],
'smallpoint_full_name' => $insertData['full_name'],
'smallpoint_user_type' => $insertData['user_type'],
'smallpoint_user_id' => $userData['id'],
'smallpoint_user_snap' => '',
'is_logged_in' => 1,
);
$this->session->set_userdata($session_array);
redirect(base_url() . 'forum/update_session.php?hasher = ' . time() . time() . time() . time() . time() . time() . '&&nohasher=' . time() . time() . time() . time() . time() . time() . '&&thisisid=' . $userData['id'] . '&&thisisrole=' . $insertData['role'] . '&&thisisname=' . $insertData['username'] . '&&op=1', 'location', 301);
=====================update_session.php======================
session_start();
require 'includes.php';
if ($_GET['op'] == 1) {
$_SESSION[TABLES_PREFIX . 'sforum_logged_in'] = true;
$_SESSION[TABLES_PREFIX . 'sforum_user_id'] = $_GET['thisisid'];
$_SESSION[TABLES_PREFIX . 'sforum_user_role'] = $_GET['thisisrole'];
$_SESSION[TABLES_PREFIX . 'sforum_user_username'] = $_GET['thisisname'];
} else {

unset($_SESSION[TABLES_PREFIX . 'sforum_user_role']);
unset($_SESSION[TABLES_PREFIX . 'sforum_user_username']);
setcookie(TABLES_PREFIX . COOKIE_NAME, "", time() - 3600);
}

Try to add the following to your code.
session_save_path("/tmp");
session_start();
I got the same problem in firefox and it works fine
session_save_path("/tmp"); // CREATE this Folder in the root
session_start();
require 'includes.php';
if ($_GET['op'] == 1) {
$_SESSION[TABLES_PREFIX . 'sforum_logged_in'] = true;
$_SESSION[TABLES_PREFIX . 'sforum_user_id'] = $_GET['thisisid'];
$_SESSION[TABLES_PREFIX . 'sforum_user_role'] = $_GET['thisisrole'];
$_SESSION[TABLES_PREFIX . 'sforum_user_username'] = $_GET['thisisname'];
} else {
unset($_SESSION[TABLES_PREFIX . 'sforum_logged_in']);
unset($_SESSION[TABLES_PREFIX . 'sforum_user_id']);
unset($_SESSION[TABLES_PREFIX . 'sforum_user_role']);
unset($_SESSION[TABLES_PREFIX . 'sforum_user_username']);
setcookie(TABLES_PREFIX . COOKIE_NAME, "", time() - 3600);
}
header('Location: ' . $_SERVER['HTTP_REFERER']);
