Once installed and enabled, this extension will automatically suspend tabs that have not been used for a default, or user-configurable, time interval. As a result, resources such as memory and CPU that the tab was consuming are freed.

If you have suggestions or problems using the extension, please submit a bug or a feature request.

3. Click Load unpacked extension....
4. Browse to the src directory of the unarchived folder and confirm.

The "welcome" page will open indicating successful installation.
