Given Firefox 18, when I use "File" -> "Close Window"
(or hit Ctrl+Shift+W)
with another browser window open and multiple tabs in the current window, I am asked "You are about to close [some number of] tabs". However, when I do the same thing in the last open Firefox window, it asks me if I want to quit and whether to save the tabs for the next invocation, without specifying how many tabs I have open in that window.
Often, I want to get a quick count of the number of tabs open, and aborting closing the window is a quick way to get that number. But as it is, if I have only one browser window open, I need to open another browser window simply to get the question I want.
Can Firefox be configured to display the count of the number of tabs also when closing the last browser window of the running instance? How?

Consider to use Tab Counter Firefox add-on - the simplest one for the task.
