The Last Tabs extension for Google Chrome allows you to find out how you were browsing. It's a very simple and fast-to-use extension, which displays the last three tabs you were on in a separate menu and allows you to flip between them by clicking the current tab in the browser. This way, you can remember the last tab you had open, even when you were browsing the Internet.

This extension offers various keyboard shortcuts, so you won't have to use the mouse. It is possible to shift-click the tab you wish to open, so you can quickly select a lot of tabs to open a new window. You can use the keyboard to move between tabs, close them or open a new one. There are also a lot of other options. It's very convenient and easy to use.
