According to FAQ of Caching Mechanism (mozilla.org), it is by design to cache “documents specifically marked for "not caching" through-- "Pragma: no-cache" or a "Cache-control:" directive specified as an HTTP response header” in memory to improve performance. So, it is possible for you to view sensitive information from the Firefox memory cache after you log out an web application and keep Firefox open.
