Comment 215 for bug 230102

To <email address hidden> and everyone else, you can install the simple "always ask" addon
https://addons.mozilla.org/en-us/firefox/addon/always-ask/
It adds an additional quit dialog that will appear when Firefox would not normally prompt (for example, when you have session restore on).
It even prompts when I by mistake shut down my windows PC and Firefox is still open.
