Cannot see refresh action

Hi,
I try to use tab-refesh with a website of a cable modem. I have to test it and would like not to be logged out during creating tickets. Therefore it is exactly what I am looking for!

I defined to refesh in an intervall of one minute for a first test.

Mouse hover tells me the correct time, when the next refresh will occur. I waited until this time and checked every second, whether this time point will change or not. Short before the time point will pass, a future time will be shown already, but no refresh will occur.

I assume the same action like pressing F5, when a refresh takes place.

"Do not refresh the tab if you are using" is active. What events are true for the state "used"?

When the "in use" option is off, it works as expected. I assume, that "Tab Refresh" thinks an event has been taken place and will not refresh. The event recognition seems too sensitive. I moved the mouse not inside the webwindow of the testes tab. The movement was only from the AddOn Icon to the tab area and back. This will be already valued as "in use", as it looks like.

When the "in use" option is on, I have to activate another Tab, then a refresh takes place. It is enough th have the Tab active to shift the timer. Is there a way to decrease the sensitivty?

Regards,

Onurbi
