Session cookie expiry based on local time

Maybe another difference: have you switched cookie encryption off?

I only use encrypted cookies, and that works file with all browsers I have at my disposal here. I'll try some testing without encryption.

EDIT: that's the issue. To fix it, in _get_cookie_data(), encode the data if no encryption is used:

Code:

// if encryption is not used, we provide an md5 hash to prevent userside tampering
$cookie_data = rawurlencode($cookie_data).md5($cookie_data.$this->encryption_key);
