You can set Microsoft Edge to open the tabs that were last active when you last used the browser.
To do this, go to Microsoft Edge Settings. You can do this by clicking the ellipses and clicking "Settings", or you can skip the below and type this into the URL Bar:
edge://settings/?search=Open%20tabs
Search "Open tabs" and then select "Open tabs from the previous session"
Now when you close and re-open Microsoft Edge, the tabs from your previous session will re-open.
