I know, I meant that "configuring it back" is just one click on "Warn Before Quitting" in the Chrome menu. See https://apple.stackexchange.com/a/340517
Oh wow. I thought you were referring to simply clicking Quit in the menu. Thank you for this. I hadn’t realized that was an option. It has bugged me for a long time.
FWIW, I turned this option (to not quit on Cmd+Q) a long time before it was the default, and it's saved me time so many times - I absolutely love it. Before, I would constantly try to hit "Cmd+W" and accidentally tap the Q, and the whole browser would close.
I’ve turned to using Alfred and typing “qgc” to Quit Google Chrome, although I use Alfred for most navigation now.
