Did you close all your tabs on accident?
You can customize “On startup” to automatically reopen all the same tabs you had open when you quit.
- Go to the top right in Chrome, and click More –> Settings.
- Click On startup to display options.
- Click Continue where you left off.
Note, that you can also click the 3 dots in the top right corner of Chrome –> click history –> and. you should see an open all tab to relaunch everything that was closed.
