Yes. "Keep until: I close Firefox" deletes cookies on exit. "Allow" exceptions override that global setting, keeping the respective cookies indefinitely.

Edit: Please note that due to bug 1406675, for the time being you also need to create Allow exceptions for most add-ons that need to store data. What you enter for "Address of website" is moz-extension://Internal UUID. Each add-on's internal UUID is different for each Firefox profile; to find it, enter about:debugging into the location bar.
