Tab Staler

This extensions allows you to create a Configuration to close tabs after they get stale. A stale tab is defined after a certain it is not active. It is possible to configure a Regular Expression (follow the JavaScript Regex Styleguide) and a certain time per Regular Expression. Every tab that matches this Regular Expression will get automatically closed if it is in the background for the specified time. Note the extension checks every 5 Seconds if a tab is stale. That means that the time the tab actually gets closed can be delayed by the 5 Seconds.
