I also get this popup when I use "Close Other Tabs" in a tab's context menu; this has nothing to do with "carrying out the Close Window operation" and everything to do with closing multiple tabs.

It seems that the missing warning when quitting the browser aims at avoiding two consecutive "Are you sure" popups if browser.warnOnQuit is also set.

I'm using
Mozilla/5.0 (X11; Linux x86_64; rv:15.0) Gecko/15.0 Firefox/15.0a1 SeaMonkey/2.12a1 ID:20120505003004
with many extensions installed including "Duplicate This Tab" but not TabMixPlus which is (alas) not available for SeaMonkey.
