Second firefox.exe appearing in the process in Windows Task Manager...

Hi all!

I started facing this problem a few days ago and do not know what is the cause:

In my Windows Task Manager, there are two firefox.exe that appear under the process (under Applications, Firefox only appears once). I used to complete the process to close each of the firefox.exe that appear and the result was special. Depending on whether one I finish, either the window closes completely as well as all tabs or hangs the tab that is currently open and I get the message: "bad new first: this tab broke down."

I scanned my computer with AVG for viruses and everything was clean back. I've also scanned with ESET for malware and nothing was found.

Any idea what I can do to fix this? Any help would be appreciated.

You may see the new multiprocessue feature in Firefox.

Code name for Firefox multiprocessu 'e10s. https://wiki.Mozilla.org/Firefox/multiprocess

Started with Firefox 48 for a very small percentage of users with noi extensions installed; expanded in Firefox 49 to a slightly more large group of users; expansion in Firefox 50. Automatically disabled when too many installed extensions are detected and extensions that do not yet support e10s are detected.

Compatibility of the extension for the most popular extensions that are hosted on AMO are listed here: http://arewee10syet.com/

To disable multiprocess:

Type of topic: config in the address bar, press ENTER, accept the warning. This in the search field at the top of the browser.tabs.remote.autostart page. Double-click this preference in the reduced list located under the search box to switch to the 'value' of True to False.

  • Version 5.0 will not offload the memory when I close. This translates not being able to open FF later unless I manually go and close the application in Windows Task Manager. Any ideas because it becomes very frustrating.

    I have this problem on 3 computers just updated with FF 5.0. When I close FF, the application "Firefox.exe * 32" remains in memory. Trying to open FF later greets me with the error that FF can't open because another instance of FF is already running. Previous versions is completely discharged and has never caused this problem...

    You can check your add on for compatibility, there may be conflicts.

    For now, you can use the command "End task" in the Task Manager to close Firefox before opening another version.

  • CS5-> CS6 upgrade hangs, block the windows Task Manager, does nothing else

    Got the CS6 Design Standard update, hoping to upgrade from CS5 Design Premium. Could it be the problem? I don't have all the added bonus and this stuff is ridiculously expensive.

    In any case, I put the disc, nothing happens. I run the set - up.exe, the disc spins, then nothing continues to happen. I watched it for up to 5 minutes and nothing.

    Set - up.exe isn't in Applications, but it's in the process in windows Task Manager. However, there is no real activity at all. When I try to end the process, WTM crashes. I have to every hard reboot or eject the disc in order to recover.

    What gives? I can post PDApp.log if need be, but I don't know how much help it will be.

Just in case someone else stumbles across this post with a similar problem, make sure that you do not install the update of an external USB DVD drive, specifically a Samsung SE-S084. It won't work.

    Note that your list of details of the system shows that you have a user.js file in the profile folder to initialize prefs each time you start Firefox.

    The user.js file is present than if you or another software has created this file and normally it wouldn't be here.
    You can check its contents with a text editor (right click: open with) If you do not create this file yourself.

    The user.js file is read whenever Firefox is started and initializes the preferences to the specified value in this file, so the preferences set via user.js can be changed temporarily for the current session.

    Delete a possible user.js file and files numbered prefs-# .js and rename (or delete) the file prefs.js to reset all the prefs by default, including the prefs set via user.js and pref which is no longer supported in the current version of Firefox.

    You can use this button to go to the Firefox profile folder currently in use:

    Hey AvisTilly,

    Unless you have installed a program called ITIBITI, it would be a good idea to scan your computer for malware. Run a full scan using the Scanner below the link Microsoft to see if he can identify or remove malicious programs from your system.

    Hi MAMARDA,

    Welcome to the Microsoft Vista answers Forum!

    I would like to ask you a few questions in order to get a better understanding of this issue so that we can better help you.

    (a) what version of Windows 7 use you?

    (b) what is the exact error message you are getting?

    Method 1: You can also try to perform a file system (scan SFC) verification tool. This tool will fix the system files are corrupted.

    Scan SFC enforcement procedure:

    1. click on the Start button

    2. on the Start Menu, click all programs followed by accessories

    3. in the menu accessories, right-click on command line option

    4. in the drop-down menu that appears, click the "Run as Administrator" option

    5. If you have the User Account Control (UAC) enabled, you will be asked permission before the opening of the command line. You simply press the button continue if you are the administrator or insert password etc.

    6. in the command prompt window, type: sfc/scannow then press enter

    7. a message is displayed to indicate that "the analysis of the system will start.

    8. be patient because the analysis may take some time

    9. If all the files need replace SFC will replace them. You may be asked to insert your Vista DVD for this process to continue

    10. If all goes although you should, after the analysis, see the following message "Windows resource protection not found any breach of integrity.

    11. once the scan is finished, close the command prompt window, restart the computer and check.

    Method 2: If this is a recent problem that has developed you can try to perform a system restore and check if it works very well.

    To restore the operating system to an earlier point in time, follow these steps:

    1. Click Start, type system restore in the search box, and then click System Restore in the list programs.

    If you are prompted for an administrator password or a confirmation, type your password or click on continue.

    2. in the System Restore dialog box, click on choose a different restore point and then click Next

    3. in the list of restore points, click a restore point created before you started having the problem, and then click Next

    4. click on finish

    Note: When you perform the system restore to restore the computer to a previous state, programs and updates that you have installed are removed.

    For more information, please follow the below given link:

    How to repair the operating system and how to restore the configuration of the operating system to an earlier point in time in Windows Vista

    http://support.Microsoft.com/kb/936212/

    Method 3: you can try to start safe mode and restore the system, if you are unable to do it in normal mode.

    For a safe boot, you can follow the below given steps:

    1. remove all floppy disks, CDs and DVDs from your computer and restart your computer.

    Click the Start button, click the arrow next to the button lock and then click on restart.

    2. do one of the following:

    a. If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then stop and restart your computer.

    b. If your computer has multiple operating systems, use the arrow keys to select the operating system you want to start in safe mode, and then press F8.

    When you are in safe mode, follow the steps mentioned above to complete the restore of the system.

    Hope the helps of information.
    Please post back and we do know.

  • Essbase Service does not appear on the list of Windows Services

    Hi gurus,

    I tried to install the Hyperion Essbase 6.2.4 on Windows Server 2003 version and most of the thing works except that the Essbase Service itself does not appear on the Panel of Windows Services, whether on the previous installation of Windows 2000 Server.

    I tried reinstalling the software but the problem is still not resolved. I need to have Essbase Service on the list to allow the availability of service 24 x 7.

    I know that the Essbase version is quite outdated, but I'd be happy to hear from you guys.

    All advice please?

    Thank you.

    In version 6, you need to set your ip to the service. Go to start run and type cmd and click ok
    Then in the command window type
    Essbase.exe - service installation and press ENTER. The device must install.

    I can't boot from a disc XP system either.

    Could this be a HW problem?

    I've extracted the original HD and put it in a usb interface

    I can read it without problem with another PC (so the HD should not be the problem)

    Thank you all

    Kind regards

    NTOSKRNL is a software, and it must be there for the machine to start.  The recovery discs should fix this.
