suggested priv. setting: Max Tabs Undo

[ajay-gh]

Setting recommended: browser.sessionstore.max_tabs_undo = 0 (or 1), default value is 10

Title: Disable FF Sessionstore Description: Even with Firefox set to not remember history, or delete history at a certain event or timer, your closed tabs are stored temporarily at Menu -> History -> Recently Closed Tabs. The user may not be aware of this behavior when setting / choosing history related preferences. It may, under certain circumstances compromise privacy. With the variable set to 1 instead of 0 (not recommended where privacy is priority) one retains the option to easily reopen the last tab after it has been closed by accident.

See https://www.privacytools.io/ for more details.

Thank you. I consider adding it to "private browsing only" or a new hardened profile. I think there are not many people using the default profile, which would really disable such a feature. But having it for a hardned profile e.g. for using Firefox with tor is nice.
