Updated link describing the behaviour from Comment 10: https://hg.mozilla.org/mozilla- central/file/934fe0bd6062/browser/components/nsBrowserGlue.js#l1248
Also pasting it here for easier search: > There are several cases where we won't show a dialog here: > 1. There is only 1 tab open in 1 window > 2. The session will be restored at startup, indicated by > browser.startup.page == 3 or browser.sessionstore.resume_session_once == > true > 3. browser.warnOnQuit == false > 4. The browser is currently in Private Browsing mode > 5. The browser will be restarted. > > Otherwise these are the conditions and the associated dialogs that will be > shown: > 1. aQuitType == "lastwindow" or "quit" and browser.showQuitWarning == true > - The quit dialog will be shown > 2. aQuitType == "lastwindow" && browser.tabs.warnOnClose == true > - The "closing multiple tabs" dialog will be shown > > aQuitType == "lastwindow" is overloaded. "lastwindow" is used to indicate > "the last window is closing but we're not quitting (a non-browser window is > open)" > and also "we're quitting by closing the last window". ---- Cases 2 and 4 are the most annoying. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/583797 Title: "Warn on closing with multiple tabs open" not honored Status in Mozilla Firefox: Invalid Status in firefox package in Ubuntu: Triaged Bug description: Binary package hint: firefox 1) lsb_release -rd Description: Ubuntu 11.10 Release: 11.10 2) apt-cache policy firefox firefox: Installed: 11.0+build1-0ubuntu0.11.10.1 Candidate: 11.0+build1-0ubuntu0.11.10.1 Version table: *** 11.0+build1-0ubuntu0.11.10.1 0 500 http://us.archive.ubuntu.com/ubuntu/ oneiric-updates/main i386 Packages 500 http://security.ubuntu.com/ubuntu/ oneiric-security/main i386 Packages 100 /var/lib/dpkg/status 7.0.1+build1+nobinonly-0ubuntu2 0 500 http://us.archive.ubuntu.com/ubuntu/ oneiric/main i386 Packages 3) What is expected to happen in Firefox, with Edit -> Preferences -> Tabs -> "Warn on closing with multiple tabs open" checkbox checked, is when one click the X, File -> Quit, Ctrl+Q , or Alt+Space -> C, one get's the confirmation box: Confirm close You are about to close x tabs. Are you sure you want to continue? 4) What happens instead is one is not warned and the window closes. PARTIAL WORKAROUND: about:config -> browser.tabs.maxOpenBeforeWarn -> change from 15 to 2. This will pop up the confirmation box clicking the X and Alt+Space -> C only. WORKAROUND: Disable Ctrl+Q quiting the browser by installing keyconfig add-on: http://mozilla.dorando.at/keyconfig.xpi Then Tools -> Add-Ons -> Extensions -> keyconfig Preferences -> highlight Quit -> Disable Original Reporter Comments: I found a "workaround" that says to set "open to a blank page" somewhere else, and I set this, but it still doesn't warn me. I work from home and frequently spend an hour or so putting in data, all on one screen. If I accidentally hit the stupid little x (which is now in the left hand corner just where you don't need it, it is too easy to hit it by accident, but i can't change this, it comes with the distro), i lose all that work.
