On leaving Firefox I get an error message, instruction could not be read or could not be written or privileged instruction

This error started when I had problems with >NET Frameworks It is annoying, not critical. When I close Firefox I get an error message, 1 of 3. Instruction could not be written, or could not be read, or Privileged Instruction. The location of the error varies each time. I have tried IE and it does not generate the same problem.

See [[Firefox crashes when you exit it]].
Does it send crash reports to Mozilla? If it does can you post some of the crash report IDs as this may help identify the cause of the crashes. For details on getting them see the [[Firefox crashes]] article.

    If there are problems with updating or with the permissions then best is to download the full version and trash the currently installed version to do a clean install of the new version.
    *Trash the current Firefox application (open the Applications folder in the Finder and drag the Firefox application to the Trash) to do a clean (re)install
    *Install the new version that you have downloaded

  • When I open firefox I get an error message "update could not be installed check for duplcates"

    Error message: The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox and try again.
    I have uninstalled all versions of Firefox. Then went to the Internet through Explorer and downloaded from scratch. A few days later I started getting the message again.

    If there are problems with updating then best is to download the full version and uninstall the currently installed version and delete the Firefox program folder to remove any leftover files.
    Download a fresh Firefox copy and save the file to the desktop.
    *Firefox 10.0.x: http://www.mozilla.org/en-US/firefox/all.html
    Uninstall your current Firefox version, if possible.

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

  • I have tried uninstalling and reinstalling Firefox several times. Every time I try to open Firefox I get an error message saying "Close Firefox"," A copy of Firefox is already open. Only one copy of Firefox can be open at a time."

    I uninstall Firefox, then reinstall Firefox, try to open Firefox, and get an error message in a popup box saying,
    "Close Firefox"
    "A copy of Firefox is already open. Only one copy of Firefox can be open at a time."

    Create a new profile as a test to check if your current profile is causing the problems.
    See "Basic Troubleshooting: Make a new profile":
    *https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
    If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

I thought if I were to completely uninstall and re install it might help, but I cannot seem to find instructions to do this....

    After installing a new version of Firefox, I get the error message "The procedure entry point JS_GetOperationLimit could not be located in the dynamic link library js3250.dll" when I try to start firefox. Elsewhere in the forum a complete reinstall is suggested; however, I can't do that because of my company's IT policies. Is there any way to solve this problem WITHOUT a complete reinstall? Thank you!

    If you can't reinstall Firefox yourself then you need to contact your IT department and ask them to check the Firefox installation.
    It is possible that some files got broken with the latest update.

    Go to settings for google shortcuts, follow link to homepage and upload latest version, it has not yet been approved by Firefox, but works and solves the bug.
    Hope this helps.

    Close all iWork applications
    2
    Uninstall Keynote; this must be done with an application remover tool to delete the installation properly. Appcleaner is known to work correctly for this purpose, it is free and can be downloaded from here: Appcleaner Download
    3
    empty the trash
    4
    shutdown the Mac and restart. After the start up chime, hold down the shift key until the apple logo appears
    let the Mac complete the start up procedure completely, it will take longer than usual as the hard drive is being repaired
    5
    Reinstall Keynote by logging into the Mac App Store using download / install

    Just had this same problem. Based on other suggestions I found on the web, went to C:\Program Files\Mozilla Firefox and deleted all files that ended with upgrade and/or delete. Then I was able to uninstall Firefox and then reinstalled. Hope this helps!

  • Ever since upgrading to Lion I keep getting the error message "disk was not ejected properly."

    Ever since upgrading to Lion on my iMac G5 Intel Core 2 Duo, I keep getting the error message "disk was not ejected properly."  I have repaired permissions and reformatted my external LaCie 2TB USB hard disk, but the error continues.  I use this disk for my Time Machine backups.  This always seems to happen when the computer wakes from sleep, but not consistently.  The computer was asleep overnight and backed up as soon as it awakend this morning.  Two hours later I get the improper ejection message.  I have used the same external disk with Snow Leopard (all versions), but never had this error message or problem.  This disk has been in use without any problems since February, 2011. Upgrading to Lion is when this problem began. This is the below message (but from online image from Snow Leopard, but Lion message is essentially the same).

    I had a similar issue. Mine was with a Seagate GoFlex drive. The solution was to install GoFlex for Mac 1.1.2 which included a 64-bit driver to disable the drives built in sleep timer:
