Comment 10 for bug 236901

Steps to reproduce:
1. Configure Firefox to open the "windows and tabs from last time" at startup and to clear private data at shutdown
2. Load any page (for a nice effect, log into your email account)
3. Close Firefox and tell it to clear all private data (at least history and cookies)
4. Launch Firefox

Expected result:
Firefox loads blank since there should be nothing to reload, i.e. sessionstore.js has been purged at shutdown.

Actual result:
All the opened pages are nicely restored, you even remain logged in.
