GUI automatically logs off the users when using Google Chrome or Mozilla Firefox

If the GUI is accessed through Google Chrome or Mozilla Firefox browsers and the tab is in the background for more than 30 minutes, the users get logged out of the GUI.

This issue is reported if no timeout is specified on the Services > GUI > Preferences page. If a timeout was specified, the GUI session expires when there is no user activity for that period of time, regardless of the active browser tab.

Note: This issue is reported on Google Chrome version 57 or later, and Mozilla Firefox 58 or later.
