This add-on doens't work at all ! In a new tab I loaded an online newspaper webpage that refreshes every 5 minutes and selected on "Tab Reloader" the option "Do not reload if tab is active", then I wait and find out that the web page was actually reloading itself as usual, so I concluded that this add-on is not working and for that I'm uninstalling it immediately this non-operative add-on !
I DO NOT RECOMMEND IT !
