When I try to open firefox, and other things appear the next tex said thatt was not able to load XPCOM

Since yesterday, I could not access internet firefox, pops up a window with the message unable to load XPCOM


Loïc Macarena SilviaFigueroa,

Do a clean reinstall and delete the program folder before Firefox to (re) install a new copy of the current version of Firefox.

Download a new copy of Firefox and save the file to the desktop.

Uninstall your current version of Firefox, if possible, the settings in the software security and cleaning of the Windows registry.

  • Do NOT remove the data personal when you uninstall your current version of Firefox, because all profile files will be deleted and you lose personal data such as bookmarks and passwords from other versions of Firefox profiles.

Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

  • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
  • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but make sure that 'delete personal data' is NOT selected when you uninstall Firefox.

If you keep problems also create a new profile.

    What have you tried so far?

    Can you try reinstalling Firefox? Uninstall it from your control panel > programs and features/add / remove programs (if you want to keep your bookmarks and other information, not deletion of personal information). After uninstallation, delete the Mozilla Firefox folder to remove the remnants of files damaged uninstallation (your profile is in a different location, so will not be affected by the present):

  • When I try to open Firefox and explore, I get a menu of recommended programs and asked me to choose the program with which to open the file.

    Original title: open Firefox and explore

    When I leave early to Mozilla Firefox or Explorer, I get a menu of recommended programs and asked me to choose the program with which to open the file. When I do, I get a security warning asking if I really want to do. If I check "Run", I get redirected to the previous list, and I find myself in a circle without end. It does not matter what choice to make. Used to be that I went from starting Firefox directly.  I can get in if I have Firefox right click and choose to run the file as an administrator and then give permission to open the program. How can I cut these two additional and direct access, that I used to enjoy. I run Vista. The same thing happens if I have to explore. Would be grateful for the help.


    1 during how long have you had the problem?
    2. don't you make changes to your computer before the problem?

    I suggest that you follow the steps below and check if the problem persists.

    Method 1:

    When you run an .exe on a Windows Vista-based or Windows 7 computer file, the file may start another program
    Method 2:
    Step 1:
    Make SFC scan and check if this is related to missing or damaged system files.
    Step 2:
    After the SFC scan, set the file association and check.

    Method 3:

    Test the issue in a new user account .

  • Receive an error about a missing file message when I try to open Firefox

    When I tried to open Firefox today I received a message about a missing (Wrusr.ddl) file and that Firefox was not able to open. I tried uninstalling and reinstalling, but it did not work. I have no idea what this file is or where it went. I used Firefox 2 days ago and it was working fine. The only thing that changed between then and now was that I renewed my antivirus software but I certainly did not remove all the files and I made sure that Firefox is permitted to access the internet. I use this same software (Webroot) with Firefox for years and never had any problems until today. Any help would be greatly appreciated! I've included a screenshot of the error message below.

  • When I try to open Firefox it says it is already running... I tried to uninstall, but it says it works... but it's not.

    It will not only open when I try to open... it says, he is already running, but is not. I tried to uninstall it, but it won't uninstall, because he says that the program is running.

    These questions can also be caused if the profile is set as default (default = 1) in the profiles.ini profile is missing.

    One possible cause is a discount action zero who has failed somehow to supplement and update the profiles.ini file correctly.

    Borrow a Microsoft Vista DVD(not Dell, HP, etc Recovery DVDs) to do a repair installation

    If you see a startup Neosmart repair disk download here, this is NOT what you want.

    You want a good Vista DVD that contains the operating system files.


    If you need a recovery media for your laptop back to factory settings, read this info:

    How to get Vista recovery Media and/or to use the Vista recovery Partition on your computer.

    There is no Vista free download legal available.

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.


    In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

    See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

    Normally, you have to press F10 or F11 at startup to start the recovery process...

    Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.


    Ask them if you can also make recovery disk/s for the recovery Partition in case of a system Crash or hard drive failure.

    They will tell you how to do this.

    Every computer manufacturer has their own way of making recovery disk/s.


    Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu


    MS advice on the conduct of clean install.


    A tutorial on the use of a clean install


    Super Guide Windows Vista Installation

    After installation > go to the website of the manufacturer of your computer/notebook > drivers and downloads Section > key in your model number > get latest Vista drivers for it > download/install them.

  • When I try to open Firefox I get a message: "update could not be installed. Make sure that there is not another instance of Firefox. Restart and try again. »

    Something.on 29 started w/FF SP3 Win XP (Home)

    Any ideas greatly appreciated.

    Back to SeaMonkey yet.

    Much thanks ideato.

    There was no possibility of not installing the update (in custom installation) as in the installation from the heel, but I went ahead anyway.
    This seems to have done the trick.
    No error messages in my my profile and FF made a successful update (see screenshot).

  • When I try to open Firefox it says "Firefox is already ongoing enforcement... » ? !

    It started yesterday after I did a reset of Firefox. It worked perfectly after that, but when I closed and tried to reopen the program I constantly get a message saying "Firefox is already running but is not responding... »

    Here are the steps I have already taken to try to resolve the problem:

    1A sought the Firefox process in my task manager to complete but impossible to locate
    2 restarted my computer
    3 has tried to open an older version of a restore point but get the same message "Firefox is already running...". ».
    4A sought solutions in support of mozilla, but couldn't find one that worked.

    Help, please!

    It turns out that I have had accidentally ticked the 'Read only' box in my AppData folder in my user account properties. This had somehow apparently prevented Firefox from termination or restart... or both, I don't know exactly why. After going back and uncheck the read-only Firefox starts fine.

    Thanks for your suggestion if ideato!
