restore-last-session Chrome flag

--restore-last-session

What does --restore-last-session do?

Indicates the last session should be restored on startup. This overrides the preferences value. Note that this does not force automatic session restore following a crash, so as to prevent a crash loop. This switch is used to implement support for OS-specific "continue where you left off" functionality on OS X and Windows.
