FIREFOX REFRESH PAGE WHEN OPENING A PREVIOUS SESSION TAB WINDOWS

In fact, it’s a new intentional change so that if Firefox is configured to enable session restore by selecting “Show my windows and tabs from last time” startup option ( pref is equal to 3), where Firefox will re-open and restore all opened tabs automatically on next restart, Firefox does not warn or prompt for confirmation when user closes a Firefox window of a Firefox session with only single window with multiple tabs or quit the Firefox application with multiple Firefox windows and/or tabs opened, as long as Firefox deems that these tabs and/or windows can be saved and reopened automatically by Firefox on next start up.

However, this new behavior looks like not going to be classified as a bug, according to replies from various developers in (see bug 422040, 434961, and 419009). In Firefox 3, this is not the case, and Firefox closes and quits without warning and confirmation even with more than one open tabs, even with “browser.warnOnQuit” preference set to true. Are you sure want to continue?”, as practiced in Firefox 2 shown in illustration below. With the “Warn me when closing multiple tabs” option selected, Firefox supposed to pop up a dialog box titled “Confirm Close” asking “You’re about to close x open tabs. The warning when closing multiple tabs not working ‘error’ happens despite that the “Warn me when closing multiple tabs” option in Tabs section of Firefox 3 Preferences has been checked and enabled.

After upgrading from Firefox 2 and installing Firefox 3, many users may notice that Firefox 3 no longer prompt or warn user before closing or exiting Firefox window with multiple tabs opened in the window.
