I sometimes close Firefox while I have downloads in progress that do not support resuming. Then when I open Firefox again I have to go to the original download location and start from scratch. It would be useful if there was a way to get a warning from Firefox before I close the application when downloads are in progress. Anyone know of a way to configure it to do this?
I'm using DownThemAll! addon and even if I close Firefox, the download window remains open as a separate window. This prevents me from stopping my unresumable downloads accidentally.
You may also want to consider to set
browser.showQuitWarning in Firefox's
true to get a warning when closing the browser, not only when a download is in progress. This might save you some headaches when you accidentially try to close Firefox and were typing text into some input boxes for example. See http://kb.mozillazine.org/Browser.warnOnQuit.
browser.download.manager.quitBehavior doesn't exist anymore; it has been removed in recent FF versions.
One (slightly clunky) workaround is to go to
Show all downloads when you're downloading something big you may forget about. It will show a new download window, independent from FF. But you have to remember beforehand.
The missing preference is just screaming for a bug report, though.
