[Plugin: WP Splash Image] Splash Screen Re-appears Firefox

I have sorted this issue with firefox, I had to enable custom setting for cookies, which solved the problem for me but needing to do this for the plugin to function properly may cause issues for some folks who like me normally only accept cookies from sites that I am very confident about, is there no other way that a timer can be integrated other than cookies ? , this is a great plugin that would be fantastic if cookies weren’t involved or would it be ?
