Site Sleeper
Site Sleeper reduces the strain on your computer's processor by putting any tab that is not currently in use "To Sleep".
To set up and use Site Sleeper, follow these instructions:
Open the Clean & Speed Up extension
Click the Sleep Tab
Turn on the Site Sleeper Button
Now, if you are not using a browser tab, the tab will go to sleep. If you would like to access your tab again, you simply click on the tab and click Refresh or Click to Reload.
Site Sleeper comes with a few customization options. These options are:
Awake List - Customize which websites sleep mode doesn't affect
