In Mac OS X v10.7 and later, the "~/Library" folder in the Home directory is a hidden folder. ~/Library/Application Support/Firefox/Profiles/.Location used for the main profile that keeps your personal data (Root Directory on about:profiles). Otherwise check "History -> Restore Previous Session" and "History -> Recently Closed Tabs/Windows". Make sure to "Quit Firefox" with all windows still open. Note that on Mac closing Firefox can be more complicated because you can close all open windows, but keep Firefox running with the menu bar visible or minimized in the Doc.
