I can not open Firefox. I keep getting the message "Failed to read the configuration file. Please contact your system administrator." I have tried uninstalling Firefox and then reinstalling it but without success. What should I do?

Which Fx version? When you uninstalled Fx, did you <b>reboot</b> computer before reinstall?
Also, check for / delete any leftover files in the Fx programs install folders, before reinstall?
Is your profile in the default location or custom location?
Have you tried creating a <u>new, <b>completely</b> clean profile</u> - to test (then make sure to select that profile to start Fx - from the Profile Manager)? (no addons or plugins installed).
Does the user acct (that Fx fails under) have access ("rights") to all locations - especially for Fx profiles location?

  • 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.

  • When I try to open iTunes, I get this error message: Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item. I get a different error message if I try to uninstall it.

    When I try to open iTunes, I get this error message: "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I've been able to uninstall all Apple products except iTunes as I get this error message: "The Installer has insufficent privileges to modify this file: C:\Program Files\i Tunes\Acknowledgments.rtf." I've had the iTunes on my laptop for a year and a half with no problems until now.

    Any suggestions please?

  • HT4623 I keep getting an error message "cannot connect to the internet."  Is this a problem with my internet provider, or has anyone else had this problem.

    I keep getting an error message "cannot connect to the internet."  Is this a problem with my internet provider, or has anyone else had this problem.

    I get that problem once in a while and I will not be able to connect to the Internet with any of the 5 or 6 (or 7 or 8 ) web browsers that I use on my iPad. The one thing that I do that has never failed to work for me is to close all apps on my iPad and reset the device. I can't guarantee that it will work for you, but this works for me every time I get the server failed to load/can't connect to the Internet message.... Or whatever the exact message is.
    If you have a ton of apps in the multitasking display, it can take a while to close them all, so you could just trey resetting the iPad first and that might be all that you need to do.
    Closing apps in iOS 7 works like this. Drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
    Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

    I keep getting an error message that says that the hard drive cannot be repaired.  Therefore I cannot get the computer to start up.

    It doesn't sound like you are doing anything incorrectly from what I can see. Have you tried restarting the iPad and then see if you can backup?
    Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
