Some times I close windows that I wish reopen later. Please add to the contextual menu of a tab the option "Reopen closed window". Just below the option "Reopen closed tab".
(A) Keyboard shortcut Ctrl+Shift+N (on Mac, Command+Shift+N) to reopen the last closed window
(B) History menu > Recently Closed Windows
The History menu is available either from the main menu button at the right end of the main toolbar, or the top menu bar (optional on Windows -- tap the Alt key or F10 key to reveal).
