User Agent: Mozilla/5.0 (X11; Linux i686 on x86_64; rv:36.0) Gecko/20100101 Firefox/36.0 SeaMonkey/2.33
Build ID: 20150308222504

Steps to reproduce:

Start firefox via "firefox --ProfileManager --safe-mode".
Create new profile and start browser with it in safe mode.
In Privacy Preferences change Remember History to Never Remember History and let Firefox restart.
Go to URL courseware.ku.edu and login to application there.
Open New Tab by clicking +
Wait at least one minute.
Go back to original tab (courseware.ku.edu) and click a link that leads to restricted content (only available to logged in user).



Actual results:

Access is denied because no cookies are sent with request.


Expected results:

Cookies previously set by login process should have been sent with request, allowing access to restricted content.

Note, this problem also happens on Windows and Mac but is much more difficult to reproduce.  On Fedora Linux it seems 100% reproducible.

I'm also attaching a cookie log showing my cookies being received and then disappearing.
