Sanity check - sessions and Firefox's save tabs feature

[eluser]WanWizard[/eluser]
Ran some tests here. If you choose the restore tabs (or restore a session in case FF crashes), all cookies of that session are restored as well. So you'll end up with a valid cookie, as if the session never stopped.

Amazon doesn't rely on only a session cookie, it also creates a session-id-time and a session-token cookie. The session-token cookie has a 10 minute expiry, so they don't work with expire on browser close, but with a fixed timeout. Which you can also do with the CI session cookie...
