Certain dynamic websites that are paranoid about security log you off automatically if you haven’t been active on the site for sometime. If you need to use such sites very often you will surely be disturbed to login time and again. So, you’ll need to do something that will keep the session running for a longer time. Session Keeper is a Firefox addon that keeps your sessions on websites with inactivity timeout for a longer period.
With Session Keeper Firefox addon installed, you can keep a session for a longer time for any web application that has invactivity timeout. After installing the addon, you’ll see a red colored icon at the bottom right hand of Firefox. Click on it to bring up the options dialogue box. You’ll need to enter the Start URL, End URL, URL to ping to keep the session live and the time interval for the ping. By default you’ll see a localhost login URL and a logout URL for the same in the start and end URL boxes.
In the Session Keeper’s settings, you need to enter the URL of the page that you see after logging in, inside the Start URL box. One drawback of this plugin is that you can only use it for a single website at a time; you cannot run multiple instances of this Firefox Addon.
