Since the installation of FF4, I wonder is if I want to save the tabs to close, and they are not open during the seizure of the next session. The only way answer correctly is opening in safe mode.

As suggested in the troubleshooting guide, I have disabled all of the Plugins/extensions, search for corrupted files potential and checked all the settings (although it does not seem to have one for this feature) all to nothing does not. FF behaves as I hope however when closing and reopening in safe mode. All previous versions of FF I got does not show this problem.

One of the changes in Firefox 4: by default Firefox 4 does not display the warning "Save tabs and exit" then to the closure of several tabs, but it can be turned on again by changing some preferences.

  • Record of the tabs was not removed from Firefox 4, but it works a little differently.

    • By default, Firefox 4 will not ask to save tabs, but instead it will always save your tabs in the output. You can restore the next time by selecting "Restore previous Session" in the history menu, or by pressing the button restore Firefox's default homepage.
    • Note: This was a decision by the developers. On this forum, we are all volunteers without compensation here to help other users. Develop them and employees of Mozilla/Firefox rarely, if ever visit here.

Browsing history must be saved

  • Button Firefox: Firefox button > Options > Options > privacy > [X] Remember my browsing history
  • Menu bar: Tools > Options > privacy > [X] Remember my browsing history

Also, make sure that you do not erase "Browsing history" when you use clear recent history or when Firefox is closed

  • Using clear recent history

    • Button Firefox: Firefox button > history > clear recent history
    • Menu bar: Tools > clear recent history
  • When Firefox is closed
    • Button Firefox: Firefox button > Options > Options > privacy (verified) > settings
    • Menu bar: Tools > Options > privacy (verified) > settings
  • See: https://support.mozilla.com/en-US/kb/Clear%20Recent%20History

To display the message "save tabs and exit" when closing multiple tabs, you can do the following:

  1. Type of topic: config in the URL/address bar and press the Enter key
  2. Accept the warning message (promise to be careful)
  3. Open the preferences/list page
  4. Filter = browser.tabs.warnOnClose
  5. If its value is set to false, double-click top (in the lower panel) to toggle its value to true
  6. Repeat steps 4 and 5 for the 3 following preferences also:
    • browser.warnOnQuit
    • browser.warnOnRestart
    • browser.showQuitWarning

  • I don't have a navigation bar and firefox does not open in safe mode to return to the default configuration. Does not work reinstall. Any help please.

    I have no navigation bar since I closed it to have more space on the screen. It will not re - open. Firefox does not open in safe mode, but immediately opens in normal mode with the new configuration incorrect, so I can't reset to default configuration. I deleted Firefox and re-installed and it always opens with the same faulty configuration.

  • Could not open in safe mode; Impossible to uninstall ESET; Impossible to uninstall RegEdit

    1 problem started trying to uninstall ESET antivirus.  Error message says that C:\Program Mechanic\Data\map.ddat Registry; C:\Program mechanic\DAta\values.dat Registry; and this: \Program Files\Registry mechanic\Data\keys.dat is missing and need to reinstall.  Don't know how to do this.  With this number, ESET says to uninstall in safe mode.

    2. for safe mode, by Windows F1 help, the "shut down" instructions say, select "restart and you select 'safe mode'.  I "turn off computer" but not "shut down" and have all the options to select Safe mode.  I tried several times to restart the computer and tapping F8 to open in safe mode.  It does not work.  By Windows, a virus may prevent it from working?   I don't know how to fix.

    3 tried to uninstall Reg Edit (don't know where that came from).  Say unistall file error message is missing.  Don't know what to do.

    Help, please.  I have no antivirus protection at the present time.  Your help would be greatly appreciated.

    Reference error messages Registry Mechanic, which has nothing to do with the antivirus/ESET security products. Using a "cleaner" as Registry Registry Mechanic probably corrupted your computer. I don't know why you try uninstalling NOD32, but to switch to secure Mode, you must turn off your computer, and then restart it. As the computer restarts, repeatedly press the F8 key. That you will get the diagnosis menu where you can use your arrow to select Mode without failure.

    I don't know what you mean by "Reg Edit" either, but my guess is that your computer is infected and that you or someone else using the computer installed all kinds of registry cleaners/optimizers garbage in a vain attempt to get it repaired. Uninstalling these programs and perform in-depth analysis of malware.

    Go through these stages of systematically General malware removal:
    http://www.elephantboycomputers.com/page2.html#Removing_Malware

    Do not skip the preparatory work.

    If you can't do the work yourself (and there is no shame in admitting this isn't your cup of tea), take the machine to a professional computer repair shop (not your local equivalent of BigComputerStore/GeekSquad). Please be aware that not all shops are skilled at removing malware, and even if they are, your computer may be so infested that Windows will have to be properly installed. If possible, have all your data backed up before taking the machine into a shop.

    The alternative is to backup your data and do a restore clean factory/install of Windows.

    Please do * not * leave the text above in a question to ask you. Delete it.
    It has nothing to do with your question. And please ask your question
    in the body of the message, not in the title.
     
    How to get deleted? If you remove them normally, they must be
    in the trash. If they are not, read point 1 below (but also pay
    Special notice to the point 2):
     
    1. "deleting" a file does not actually delete it just marks the
    available space be used. There are third-party programs that can
    sometimes recover deleted files. The problem is that the space used by
    the file is likely to be replaced very quickly, and it makes
    the unrecoverable file.
     
    So your chances of successfully recovering these files are decent if
    you try to recover immediately after their deletion and quickly
    down from there. If you use the computer since
    (for example to read this answer and write that question), your
    chances may be very weak now.
     
    But if the file is large enough, it's still worth a try. Stop
    using the computer in question immediately, if you have not done
    already. Download an undelete program (and here's one:)
    others to choose from; Do a search) on a friend's computer and bring
    it to you on a floppy disk, CD or USB to try.
     
    If that fails, your only recourse is to bring or send the disc
    a company of professional file recovery. This kind of service is very
    expensive and may or may not work in your case.
     
    2. If you have files that are important to you, and you do not
    back them up regularly, you are playing with fire. It is not a question
    to know if you lose them, it's a question of * when *. You could
    you want to read this article on the backup that I wrote:

  • Can not open in safe mode / clear the cache because firefox is frozen

    I tried to load a page which seems to have had a built-in buggy video ad, and now Firefox is stuck. It stops responding, but when I force quit and reopen it, it opens the offending page, still too and it freezes again. I tried to restart my computer and reinstall Firefox and the problem continues to be. I can't follow the advice I've seen here on open mode without failure or clear my cache, because Firefox crashes before I can do it. I there a way to make these Firefox outdoors? I use Mac OS X 10.6.8 if that matters.

    Thank you!

    Hello

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    If Firefox does not work, you can start Firefox in Mode safe as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.
