Preferences dialog is not modal. It is possible to close all other browser
windows while the preferences dialog still remains open.

Reproducible: Always
Steps to Reproduce:
1. Start the browser.
2. Edit | Preferences...
3. Close the browser window (possible since preferences dialog is not modal)

Actual Results:  
Browser windows close and only preferences dialog remains

Expected Results:  
Should not be able to close browser window if preferences dialog is open.

bug 206651 requests that the preferences dialog be made non-modal for Firefox.

A non-modal preference dialog could be useful (for example, copying proxy
addresses to the proxy configuration from the browser window), but one should
not be able to close the main browser window if the dialog is showing.

Nothing to do with modality.  The close handler should check that there are no
random windows hanging about.  It's not specific to prefs; you get the same
issues with page info, bookmarks, view source, download manager, etc.  Those
should none of them be modal.

I think this bug is pretty serious. For example, when doing something that
causes a dialog to be displayed (such as loading a secure page with some
unsecure content or submitting a form), you can close all browser windows before
the dialog actually pops up. So now you have a dialog window with no browser. Eek.

A typical Mozilla can summon preferences from the browser, editor, mail,
compose, inspector, there may be others, there's no way we can make preferences
dependent let alone modal.
