I did try different pages and it didn’t work. I mainly use it on a single forum page. The only think is that I am wondering if it is working now but I don’t have a good test page. Setting it to one minute and I can see activity. Changing it to 5min and it still seems to reload after 1min.
In the past I tried a custom reload and it seemed to continuously reload so I abandoned that.
How should I be able to see if it is enabled? I would have expected some sort of check mark in the context menu or icon on the tab
