In the settings, there is an option that says “Continue where you left off” under “On Startup” option. That should keep your tabs intact when you close and launch chrome every time.
This will work for both the hotkey and manual close.
On a Mac (MacBook Pro)
Use the “command –> Q” shortcut or click on your screen’s top-left menu option “Chrome –> Quit Google Chrome” or from your Dock (typically at the bottom of your screen) right-click on the Chrome icon then choose Quit. Any of these will preserve your tabs. That is… if you have already selected the Chrome option to ‘Continue Where I Left Off’.
Using the Red ‘X’ icon at the top-left of your Chrome browser window, to close the browser, will not preserve the tabs.
You need to select Quit Google Chrome from the dropdown menu and the next time you open up the browser your tabs will be in tact. When you use the hotkeys it doesn’t work.
Mac & PC
Go to settings and under On Startup select ‘Continue Where I Left Off’
The latest versions of Chrome automatically save your most recently closed tabs.
I have also verified that this works when using the Ctrl + Shift + Q command.
This process is much better than using “Continue where you left off”. Because if you actually do want to close all the tabs you do not have to close them all one by one.
