How to enable Chrome's "continue where you left off" for OS X El Capitan? I need Chrome to restore last session tabs after closing its whole window. 
Simple "continue where you left off" does not work when I close Chrome's window.

I was looking for the resolution but all I got is useless answers provided by apple fanboys "that is the proper way - closing window does not mean closing a program". Sincerly, I don't accept it.

How to achieve proper behaviour of "continue where you left off"?
First, you want to make sure the setting is enabled in Chrome.    In the upper left corner of the screen, you'll want to click on Chrome -> Preferences and make sure the "continue where you left off" button is checked.

Next, please do understand there is a difference between closing a window and closing a program.   Command - Q is used to exit a program completely.    In OS X, if you close a window using the "red x" in the upper left corner, you are closing out a window, and not the program.    

To see this work correctly...  try opening 3-4 tabs.   Then press  Command - Q.    Then relaunch Chrome.   You should see all your tabs there.
