When I close the Firefox window, I get the warning that I am closing multiple tabs. The tabs back on reboot.

When I have more now open tab and I use the x in the window close the browser I get the warning that I close x number of tabs. If I click on continue it closes the window. It's still all I had to do to end the session and close all. Now when I restart Firefox all tabs that were closed at the previous session appear on the new page. If what is expected, why do I get the warning. This just started happening. Version is 32.

Did you remove the user.js file because this file is the main cause of the problem?

With the extensions.autoDisableScopes pref, you can control where extensions can be installed.
It is one of the predefined files that define the default values for preferences (you can check these files through the address bar).

  • Resource:///defaults/Preferences/Firefox.js
// Disable add-ons that are not installed by the user in all scopes by default.
// See the SCOPE constants in AddonManager.jsm for values to use here.
pref("extensions.autoDisableScopes", 15);
  • Resource://GRE/modules/AddonManager.jsm

  • When I close firefox it tells me that I am closing multiple tabs. and will not let me save them. the only option is to cancel or OK.

    This has just begun. When I close firefox it tells me that I am closing multiple tabs. and will not let me save them. the only option is to cancel or OK. When I say OK and restart Firefox all my tabs go :-( This happens every time now. I know how to recover my old tabs but whenever I close Firefox it always warns me that I'm closing multiple tabs.

    Do not use 'Clear history of Firefox closing' to clear the 'browsing history '.

    Using the "Show my windows and tabs from last time" is a more reliable way to restore the session data.

    • Tools > Options > general > startup: "When Firefox starts": "show my windows and tabs from last time '.

  • How can I stop Firefox closes when I close the last window open?

    I had to get Windows 7 reloaded and my backup was corrupted (i.e., I couldn't use my custom Firefox.) So I downloaded the new Firefox and now it closes automatically when I close the last window opened. I prefer that Firefox stay open until I chose to close it. How to achieve this?

    Hello 1DKG, do you mean when you close the last open tab? If yes you can replace it as follows:
    enter on: config in the address bar of firefox (confirmed the message information where it appears) and search for the preference named browser.tabs.closeWindowWithLastTab. Double-click it and change its value to false.

  • my firefox closes when I close the window, but the process is not stopped since I got the update to firefox

    Since I upgraded to firefox 2 days ago, there a reboot problem. When I close the firefox window, it closes as it normally does, but whenever I try to restart firefox it shows the notification that firefox still works and I first need to stop the previous process before you can start a new one. Finally after I manually stop the firefox process it restarts again.

    What fixed it for me, but I am running v.15 because of other problems. I have to say I tried a hundred things and nothing works. I made the note never stop, even hours later, if I forgot to go to the Task Manager to end the process. It seems not important to know if I had extensions or modules running or not. I tried this before today. My graphics driver updated a couple of months. In any case, THANK YOU for this, finally something is going right.

  • Closed Firefox tabs without giving me a warning, even if I have checked "notify me when I close the tabs.

    So far, Firefox always pop - up would be the "danger; you are about to close x number of tabs"window when I tried closing Firefox with several tabs open. Today, however, it just closes directly on my desktop, regardless of the number of tabs are open. "Warn me when I close the tabs" checked in my menu "Tab of Options", but this still does not work. I always get warned if trying to open too many tabs at once, but he refuses to tell me when I close my tabs.

    I tried checking and unchecking options, restart the computer, checked my plugins for exceeded those (the only potential problem is Shockwave Flash 17, but the other options to aide said Shockwave Flash 16 was the problem), sought user.js and went almost all the suggestions on the forums. Nothing's worked, and at this point I'm stumped.

    (Also, I'd rather have Firefox clear my history when I go out, so just having my restored tabs when I restart Firefox is not my preferred option).

    This problem started this afternoon; It was fine earlier in the day. This is due to an update of windows, an update of Firefox, or some strange virus?

    THE SECOND UPDATE: I managed to locate the problem. Tab Mix Plus add-on is apparently not compatible with the latest Firefox update. Turn it off seems to have solved the problem for now.

  • Firefox 4 warn me / restore when I close the multiple tabs.

    Even if in the Options, I checked "Warn me when closing multiple tabs" Firefox 4 don't warn me or restore the tabs when I close the multiple tabs. I use Windows Xp SP2.

    If you want Firefox to display the message to save the session, it can be turned on again by changing some preferences.

    1. Type of topic: config in the address bar and press on enter
    2. Accept the warning message that appears, you will be taken to a list of preferences
    3. Find browser.tabs.warnOnClosepreference, if its value is set to false, double-click on it to change its value to true
    4. Repeat this for 3 preferences browser.warnOnQuit, the browser.warnOnRestart and the browser.showQuitWarning

  • Windows 8 do not sleep when I close the lid

    I just got the Elitebook 850 G1 and I put all the parameters of sleep when I close the lid and wake up when I open it. I checked the two settings in windows and in the BIOS and it's all good, but when I do actually, he does not wake up but restarts the computer instead. So when I was away typing on Word, fortunately I constantly save it but it's not back to where I left off. I thought it was one of the graphic drivers first, because he has dual graphics, intel and ati. He had a few problems with the ATI card, but I think that I fixed it. I am running windows 8.1 Pro.

    What can I do else?

    Edit:

    I tried changing the settings to hibernate instead, and what he gave me was a BSOD.  Video_dxgkrnl_fatal_error. I remember that what made the first time I tried to do it before when he was on the way 'sleep'. any suggestions?

    is not serious, I fixed it. It turns out that the new graphics driver intel was the culprit. I had to revert to a previous version. works perfectly now
