Thank you for installing X-notifier, how can I disable the popup?

Hi all,

Is there an option to disable the popup at every update? I have it installed on my grandmother's pc and it would only confuse her...

I don't get any pop-up so I asume I turned it off.  There are many options.  Go to Add-ons, select extensions on the left and then find X-Notifier and click on the Options button.
