Comment 124 for bug 230102

Win 2000; Firefox 3.0 and a clean installation of 3.1b2 (both behave the same way)

I- If we agree that the goal of seeing a warning can be achieved via an incorrect method as mentioned in comment #118; i.e. a warning to save tabs to be used instead of the old warning that multiple tabs are being closed; then the easiest method is to set the existing parameter
browser.warnOnQuit to true (no need to create a new one).

II- I find it both inconsistent and definitely confusing when in both versions 3.0 released and 3.1b2 the default setting "out of the box" is
       In firefox.js file: pref("browser.warnOnQuit", true);
and yet when looking at about:config we see
                browser.warnOnQuit user set boolean false

so who and how does this default change and more importantly, how many more of them are there that do not follow the preference settings of the file?
