Values and purpose: session restore.
Positive integer or -1 means store POST data. Which will be send again.
Therefore the other mentioned pref must be also created before use and must be set to prevent re-sending POST data like buy orders or mail from secure sites.

is used for pref browser.sessionstore.privacy_level.
