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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/583797 Title: "Warn on closing with multiple tabs open" not honored To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/583797/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
