I am getting the following reading when I click on Firefox: "The application or DLLc:/programfiles/mozillafirefox/xul.dll is not a valid windows image

I am getting the following pop up reading when I click on the Mozilla Firefox icon located on my desktop: "The application or DLL c:/program files/mozillafirefox/xul.dll is not a valid windows image" I have always used mozilla and now I have no connection to the internet with it. I have tried to go to Mozilla.com to download again and I can't seem to locate a version to download.

michaeleen, you can fix this with a clean install of Firefox:
1. Download the Firefox installer from [http://www.mozilla.com/products/download.html?product=firefox-3.6.7&os=win&lang=en-US this direct link] and save it to your desktop or other location.
2. Make sure that Firefox is closed completely
3. Delete the Firefox installation directory (On Windows, this is typically the C:\Program Files\Mozilla Firefox folder that contains "firefox.exe" and other Firefox program files and folders).
4. Reinstall Firefox by running the installer you downloaded previously.
Your personal settings, including bookmarks and history, will not be lost.

  • Error message: Bad Image: The application or DLL C:\Program Files\Mozilla Firefox\MOZCRT19.dll is not a valid Windows image. Please check this against your installation diskette.

    I was in Firefox but I exited. Soon I opened it again, it
    installed updates and this message showed up. I tried
    scanning the file, looking at it, and everything short of
    reinstalling Firefox (which every other person with this
    problem has tried but it has not worked.). I installed
    Firefox by USB drive, not a diskette, and I no longer have
    it with me, so I can't check it from there. What should I
    do to fix this problem?

  • Am getting this message when I attempt to open Firefox: "The application or DLL F:\Program Files\ Mozilla Firefox\nss3.dll is not a valid Windows image. Please check this against your installation diskette."

    I had responded favorably to the upgrade message from Firefox but after the download I kept getting a Firefox message that I had to close all other instances of Firefox running before the installation process could complete. There were no other open Firefox programs! I re-booted and tried to open Firefox, and the Windows alert already cited started, and Firefox will not open.
    Checking via Windows Explorer it appears that I still have version 3.6.

    I resolved the problem. I went to CNet and re-downloaded the upgrade. It proceeded as intended and the upgrade is installed and running with no loss of plug-ins, bookmarks, etc.

  • Tried many of your suggestions but still can't get past "mozalloc.dll is not a valid windows image" when trying to install and run firefox 6

    I have downloaded new copies, deleted everything including install directory, run three different av programs and eliminated anything found. the only other copy of this file in my computer is in the thunderbird directory. Any other suggestions? FF 5 was running ok until I tried the upgrade. Now I can't install any version.

    Solved problem. ran a registry cleaner, ran chkdsk and defrag on partition that now has the program installed on it, and on the partition that contains the "'temp" directory. also cleaned out the latter.

  • When I click on my Firefox desktop shortcut, this message appears "The application or DLL C:\Program Files\Mozilla Firefox\MOZCRT19.dll is not a valid Windows image. Please check this against your instillation diskette". I cannot enter the program.

    I believe that my question gave all the details. I am wireless in my home and the other computers connected to this wireless have no problem getting into Firefox. What is MOZCRT19?

    clementem,
    This means there is a problem with the files you need to run Firefox.
    Try a clean reinstall:
    1. Download the Firefox installer from [http://mozilla.com Mozilla.com] and save it to your desktop or other location.
    2. Make sure that Firefox is closed completely
    3. Delete the Firefox installation directory (On Windows, this is typically the C:\Program Files\Mozilla Firefox folder that contains "firefox.exe" and other Firefox program files and folders).
    4. Reinstall Firefox by running the installer you downloaded previously.

  • I have uninstalled and re-downloaded firefox 3 times now and each time I get and error message saying that firefox is not a valid windows image? I download it from your website but to no availe

    This is the error message I get when I try and open Firefox:
    ''The application or DLL C:\Program Files\Mozilla Firefox\WSOCK32.dll is not a valid Windows image. Please check this against your installation diskette.''

    wsock32.dll is a Windows System file which is used to connect to the internet. if you are seeing this error message then its probably because either your Antivirus program might have moved this file to the Virus Chest or this file was Deleted mistakenly. Try Restoring this file from your Anti Virus software or check if it is still available in the Recycle Bin folder.
    If above suggestions don't work, see this:
    ''This error is a tough one as it severely limits the programs or apps that you can run in Windows. This error pops up every time you try to open a program in windows, well not every program but most. Most spyware programs can’t be ran because this error pops up and prevents it.''
    ''One would think that the solution would be to repair the invalid .dll, but what ended up fixing it for me was extracting a fresh copy of explorer.exe. It looks like explorer.exe had gotten corrupt for some reason and was causing the bad image errors with certain .dll s.''
    ''To repair the problem open up '''msconfig''', it is actually one of the few programs in windows that would still open. To open it click on Start -> Run ->Type in '''msconfig''' and hit Enter. Once it is open click on the button that says “Expand File”. From there you will select the file that needs replaced and the location of the good file. Most of the time the good file can be found in the i386 folder of your XP install cd. My msconfig didn’t like the directory “C:\Windows\System32\ that was already filled in, so browse to the Windows\system32 directory and it should work just fine.''
    ''Expand the file, it will look like nothing happened, that is normal. Reboot the computer and you should not get the errors anymore.''
    ''To be safe, I expanded the Wsock32.dll file as well, so if for some reason your error still persists try expanding the dll file too.''

    You don't have to be "in" Safari for it to cancel logout.
    You have several different Applications open, and any one of them may cancel logout if conditions are just right.
    Quit the Applications you are no longer using and your Mac will run better and faster. And it will logout instead of cancelling.

    I've tried uninstalling and reinstalling with the same problem

    Hi gfrancom-
    I do not know precisely why you are getting this error. I would suggest doing a full uninstall, and then installing the latest version.
    * Get the latest version here: http://www.mozilla.org/en-US/firefox/new/
    * Uninstall your current Firefox version.
    * Do not remove personal data when you uninstall the current version.
    Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
    * It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
    I hope that helps!

  • Newly installed firefox has left an blue "drive" icon on my (Mac) desktop that I cannot erase. When I click on firefox in applications, it always brings this up and won't start firefox directly. I cannot erase this "firefox" drive icon, it won't let me. E

    The icon is blue with a white firefox logo on it. My only options are to "Burn 'Firefox'" or "Eject 'Firefox'" when I click on it to edit it, but I cannot cut, paste, or move to trash. It won't let me. When I click on "Eject 'firefox'" it says "The disc firefox is in use and could not be ejected". Even when I am running no applications whatsoever.
    When I click on this icon, a small window appears with two icons in it: one the firefox browser icon, and the other the applications folder icon with an arrow inbetween the two. When I drag the icon into the application folder it tells me:
    "An item named 'firefox' already exists in this location. Do you want to replace it with the one you're moving?"
    And no matter how many times I "replace it" the icon never goes away.
    And no matter how many times I replace it, whenever I click on the firefox icon in applications, it brings up this tiny window on my desktop before it will actually start running the firefox web-browser. And it will never reload my previously saved tabs is also my main concern.
    == This happened ==
    Every time Firefox opened
    == a few weeks ago since I installed...

    Maybe you copied the icon show in the window to your application and into your dock directly. Try closing your Firefox again. Eject the disc again. Then go to your application folder. You should see Firefox with a circle and cross through it. Open it. It should open without the blue icon appearing on your desktop again.

  • WHY DO I GET AN UNENCRYPTED CONNECTION WHEN I CLICK ON FIREFOX

    WHY DO I GET THIS MESSAGE WHEN I OPEN MY MOZILLA BROWSER - (ALTHOUGH THIS PAGE IS ENCRYPTED, THE INFO YOU HAVE ENTERED IS TO BE SENT OVER AN UNENCRYPTED CONNECTION AND COULD EASILY BE READ BY A 3RD PARTY. WHEN I HIT CONTINUE I GET IN - WHEN I HIT CANCEL, NOTHING HAPPENS. AM I SAFE OR NOT

    I can work around it - found a forum post that helps, amidst all the other crap and guesses out there. Or perhaps it just really depends on what the root problem is, which may (conceivably) vary from machine to machine.
    https://discussions.apple.com/thread/3074512
    For me, if I right click on one of the downloadable trailers and open it in a new tab/window, and then save that once it has been loaded, I can view the trailer. Although about 25% of them come out with distorted aspect ratios and flipped on the x-axis. Very annoying workaround. It is a bit of a shock that Apple managed to screw this up somehow and is not really addressing it very well - calls to support (and from what I read in the forums echo this) result in "Apple does not officially support Quicktime". Bother!
