Abstract: A network browser is provided with working list maintenance and creation facility which contains an indicator for each URL's listing duration level of permanence for controlling how long a URL will be kept or maintained in the working list and also includes an activity duration permanence level indicator for controlling how long the URL will be kept active. This enables the browser to maintain multiple, concurrently active URLs and thereby enable the browser to provide the functional emulation of a desktop working environment to the user.
