Firefox to start says failed to load XPCOM

I use the latest version of Firefox on my Windows XP SP2 and when I try to run Firefox, it says that was not able to load XPCOM and also no other browsers (I tried IE, Chrome) just doesn't work, they do anything - Please HELP.

Seems a bit default solution for "could not load XPCOM" - uninstall FF.

  • All of a sudden I can't launch firefox, message says: unable to load XPCOM, what should I do?

    Can't get on the line, the browser says "failed to load XPCOM" icon, what can I do? Help, please. I'm not very savvy computer. Please keep it very simple.

    This may be caused by an update of Firefox failure that left you with a mixture of old and update files in the Firefox program folder.

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

    If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.

    • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

    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 do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.

  • At the start of what Firefox says "could not load XPCOM.

    My desktop is running Windows 8, which recently crashed. Since then, whenever I start, 17.1 Firefox (which is in the folder startuo) does not load, but shows an error window saying (unable to load XPCOM). Rejecting the window then allows me to start Firefox myself. I uninstalled Firefox (but not personal stuff), downloaded a new copy of Firefox 17.1 and re-installed... same thing happens.

    Just to clarify... This only happens only once, after the initial start of the desktop computer. I close the error window and everything is fine after that.

    Bright ideas please?

    What makes XPCOM reference? A missing dll file? can I find this file elsewhere and move it to the correct location?

    Many ways.

    Thanks again for all the responses.
    I now put Firefox in my 8 and restarted Windows startup folder.
    All right, Firefox (or Thunderbird) starts as it is supposed to and there is no sign of an XPCOM related error message!
    So... I have to assume that the problem was (somehow) caused by crash my Windows 8 and that (somehow), remove the Win 8 of Firefox startup folder, restart, then put Firefox in the startup folder, and then restart, has put things back where they used to be. A little strange, but I hope that the above may be useful to someone else with a similar problem in the future.
    Well cordially to all.

    Hi Madoo17,

    Welcome to the community of Microsoft and thanks for posting the question. I've surely you will help find a solution on the issue.

    1. Once you get this error message?

    2. it worked before?

    3 did you changes to the computer before the show?

    Perform the steps:

    Method 1:

    Put the computer in a State of boot is a way to know which application is causing this problem.

    To help resolve the error and other messages, you can start Windows by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    Step 1:

    Put your boot system helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.

    Follow the steps in the link below to do the same thing:

    How to configure Windows XP to start in a "clean boot" State

    Note: After troubleshooting, be sure to set the computer to start as usual as shown here:

    Step 2: To configure Windows to use a Normal startup state

    After you have used the boot is a way to solve your problem, you can follow these steps to configure Windows XP to start normally.

    a. Click Start and then click Run.

    b. type msconfig and click OK. The System Configuration Utility dialog box appears.

    c. click on the general tab, click Normal Startup - load all services and device drivers and then click OK.

    d. When you are prompted, click on restart to restart the computer.

    Method 2: Use the (SFC) System File Checker tool.

    SFC system gives an administrator the ability to scan the files all protected to check their versions. If the System File Checker detects that a protected file has been replaced, it retrieves the correct version of the file in the folder cache (% Systemroot%\System32\Dllcache) or the Windows installation source files and then replaces the incorrect file. System File Checker verifies and repopulates the cache folder also. You must be logged in as an administrator or as a member of the Administrators group to run the System File Checker.

  • I can't open Firefox, it says could not load xpcom. Who is wrong?

    I have windows vista. After the updates of windows, Firefox does not work. What should I do?

    I did exactly what suggested you - went to the Mozilla website and clicked on the Download"" button. He did his thing, I restarted my PC - to be sure and then clicked on the "Mozilla Firefox" icon on my toolbar and its openness.
    The more frustrating is that while "Firefox" wasn't working, I was forced to use other browsers - I couldn't believe all the crap and pop ups that me presentations.
    Thanks heaps

  • At startup I get a box with "Hotkey failed" and the right to another says 'Failed to load DLL' Please help!

    When I turn on my computer, WindowXP rises and few seconds more late two small boxes with the "DLL Load Failed" and doesn't have a keyboard shortcut appears.  I rebooted into «Safe Mode "and it's good that someone can give me a solution?»

    Looks like you may have a virus or other malware. Get your updated antivirus program and boot into Safe Mode. Note that some viruses can hide from your normal antivirus program, so you really need to scan in Safe Mode. To enter in Safe Mode when you turn on first, press F8 on every seconds until you get the menu, and then select Safe Mode. Then run a complete system scan.

    If that suits him fine. If this is not the case, use system restore to go back to an earlier date at the beginning of the problem. To run system restore, click Start-> programs-> Accessories-> System Tools-> system restore. Click on the box that says show more restore points.

    You can check the corrupted system files. Open an administrator command prompt and run SFC if the above does not help. Click START, and then type sfc in the search box, right-click to SFC. EXE and click run as administrator. Then, from the command prompt type sfc/scannow.

    Finally if all else fails, you can look at the rather cryptic system event log. To make, click Start-> Control Panel-> administration-> event viewer tools. Once in Event Viewer system log-click and scroll entries looking for these "error" with indicator see if you can find guidance on where the problem may be.

    I hope this helps. Good luck.

  • When I click on the Firefox icon, it says: "cannot load XPCOM. What can I do?

    When I started this morning at the computer and clicked on the icon of Firefox, I received the message "unable to load XPCOM. What can I do to fix this?

    Hi, this problem can often be solved by performing a clean reinstall. This means that you delete your Firefox program files, and then reinstall Firefox. This process does not delete your Firefox profile (such as bookmarks and passwords) data, since this information is stored in a different location.

    To do a clean reinstall of Firefox, follow these steps: Note: you can print these steps or consult them in another browser.

    1. Download the latest version of Firefox from mozilla.org office (or choose the download for your operating system and language on this page) and save the file to install it on your computer.
    2. Once the download is complete, close all Firefox Windows (or open the Firefox menu

      Click the close button

      ).

    3. Remove the Firefox installation folder, which is located in one of these locations, by default:
      • Windows:

        • C:\Program Files\Mozilla Firefox
        • C:\Program Files (x 86) \Mozilla Firefox
      • Mac: Delete Firefox in the Applications folder.
      • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
    4. Now, go ahead and reinstall Firefox:
      1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
      2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

    More information on the resettlement of Firefox can be found here.

    WARNING: Do not use an uninstaller to third parties as part of this process. This could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and passwords saved. They can be retrieved easily unless they have been backed up on an external device! See back up and restore the information contained in the profiles of Firefox.

    Please report to say if this helped you!

    Thank you.

    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):

    • (installation of 32-bit) C:\Program Files\Mozilla Firefox
