i have a very simple firefox addon that essentially just displays the total number of open tabs.
So far it works beautifully, however after right clicking on the toolbar and selecting Customize… it only shows the default text until a tab is opened or closed.
i presume that i need to add an event listener for this event and call updateWidget(), however i can’t find it in the API doc. So does anyone know how to do it?
