Reload All Tab:
This Mozilla Add-On helps me reload the page when I am not in front of the system.
In testing, it helps me Reload the page so that Server doesn’t log me out of the application. You can easily set the time when a page should reload like 5s, 10s, 1m, 10m etc. It can be enabled for the single tab or all the tabs.
