I frequently research using multiple FF windows with multiple FF tabs. When the open number of FF windows exceeds 5 or 6, all the open windows group together under one task bar button. Clicking this button brings up a list/menu of all the open FF windows with information from the last viewed tab.
Is there a way to uniquely name the open FF windows as they appear in the task bar FF group button. I had hoped that using the Group Tabs function would give what I want as the tabs group displays it's (user)given name in the FF window title bar but this name is not transfered to/under the task bar grouped window button.
