After installing the latest update, firefox keeps giving me "not responding" message and has slowed down

In addition, whenever I open tabs the browser starts pausing for a while. This didn't happen before. I think there might be some sort of inconsistency in the latest update of firefox which was automatically installed yesterday.

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] (don't forget to select ''Disable all add-ons'' when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and themes and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem does not disappear when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.

  • After downloading the latest update, Firefox starts but is not responsivc

    Mac Version
    When I opened Firefox a message appeared that an update was available. Soon there after another message appeared that said and error occurred while attempting to update. It was suggested I download the update manually which I did.
    After the download was complete, I tried to open Firefox and it opened with all of the menu items showing but the browser window was blank. (I had Google as my home page)
    I could click on all the menu items but nothing dropped down.

  • My iPhoto keeps crashing after installing the latest update, can't do anything!

    My iPhoto keeps crashing after installing the latest update, can't do anything! It used to crash when importing but now I'm at the point where I open the software and after 2 seconds it crashes (nothing connected either). What to do? Can't access any photos

    Try this:  launch iPhoto with the Option key held down and create a new, test library.  Import some photos and check to see if the same problem persists. If you can create a new library and import some test photos then the problem lies with your original library. 
    If that's the case make a temporary, backup copy (if you don't already have a backup copy) of the library and apply the two fixes below in order as needed:
    Fix #1
    Launch iPhoto with the Command+Option keys held down and rebuild the library.
    Select the options identified in the screenshot. 
    Fix #2
    Using iPhoto Library Manager  to Rebuild Your iPhoto Library
    Download iPhoto Library Manager and launch.
    Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
    Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
    In the next  window name the new library and select the location you want it to be placed.
    Click on the Create button.
    Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
    If iPhoto crashes while trying to create a new library then try this:
    Make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
    1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
         User/Home()/Library/ Preferences folder.
    2 - delete iPhoto's cache file, Cache.db, that is located in your
         User/Home()/Library/Caches/com.apple.iPhoto folder. 
    Click to view full size
    3 - launch iPhoto and try again.
    NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
    If that fails to help a reinstall of iPhoto is indicated. To do so you'll have to delete the current application and all files with "iPhoto" in the file name with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/  folder,
    Click to view full size
    Then install iPhoto from the disk it came on originally and apply all relavant updaters.
    P.S.  If you're still running Tiger, 10.4.6, then the above may not apply.  If you're running a newer system you should update your profile so we have a better idea of where you're at.

  • Since installing the latest update, Firefox will not load; it gives me the following error -- XML Parsing Error: not well formed.

    since installing the latest update, Firefox first operated with some errors but now will not load at all; it gives me the following error --
    XML Parsing Error: not well formed
    locations chrome://browser/content/browser.xml
    Line Number 1191, column 20:
    utton id="back-forward-dropmarker" type="menu" chromedir="&locale.dir;"-------------------
    please note that the words "utton ID" are exactly as the error message gives it; and at the end of the message there are exactly 19 hyphens.
    I don't know why this faulty code is referencing things to do with "chrome"... the Chrome browser is not installed on this PC or anywhere on our network.
    Also, this is not the first problem I had after clicking Firefox's prompt for the latest update. Before Firefox retreated into this error message, it was loading but running with some faults...
    1. the bookmark symbol was not appearing on the right hand side of the URL line, so I had always to click on "bookmark this page", after which the bookmark symbol did appear; however I don't know if the bookmarking function worked properly.
    2. the back and forward buttons were not highlighted, as if I had not come from a previous page; so once I clicked on a link to a new page I could not go back to where I came from because Fiefox thought I hadn't come from anywhere.
    3. there may have been other errors, but I did not find them.
    How do I reinstate my Firefox program to work properly please? do I have to download the latest version and reinstal? if so, do I have to remove the old version first? or is there a fix?
    Even to write this message I have been forced to use (yuk -- I don't like to say this!!!) Internet Explorer. So please -- I need help urgently.
    Thanks,
    NOEL

    Some how I solved my problem by opening a user account and downloading Firefox 4.0 beta and installing it, I did try it, worked fine, so I did close the user account and did go back to my own account(switched user), the main page that I had problem with Firefox which would not open, I dabble click on Firefox it start working again!! I hope that solves your problem too.
    firefox will not open, it gives me this cod and would not turn off, Error on switching in renew: NS_ERROR_UNEXPECTED, Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref] id: none

    Yes, it confuses a handful of you. Just not the other 3 million plus users who downloaded it. Maybe tell Apple instead of yelling at we other users.

  • After installing the latest updates, my iMac will constantly crash and reboot.

    After installing the latest updates for Mac OS X yesterday, my iMac constantly crashes and reboots. It will only boot properly in safe mode. Even when starting with command+R for recovery the kernel crashes. I have had this iMac for about 3 years and never had an issue until last night, when this problem started and it seems to have gotten worse over night. I already tried the <option><command><R><P>, but it seems that that made it worse as well.

  • HT4623 When I try to do the iOS7 update, it keeps giving me an error message saying "an error has occured in dowloading." What could this mean? It doesn't tell me anything specific as the error...?

    When I try to do the iOS7 update, it keeps giving me an error message saying "an error has occured in dowloading." What could this mean? It doesn't tell me anything specific as the error...?

    Got the same thing. Was in the middle of the download (11 mins remaining) and a blasted text message came through. Answered it, like a moron, and when I went back to download it gave me the error.. Very annoying. Anyway, perseverence paid off as after 10th or something re-attempt, it began again. (32 mins remaining). Like the guy above says. Severs will be going mental at the moment so stick with it.

    Hi mcclausky, you may need to manually remove a policy setting from the registry. You also should scan for malware that might have created this problem.
    This article lists scanning and cleaning tools other Firefox users have found helpful: [[Troubleshoot Firefox issues caused by malware]].
    To check your Windows registry for policy settings that might affect Firefox or other programs, I suggest consulting a Windows forum or Microsoft's forums. For example:

    Is there a bug with the latest update to iTunes because I am unable to install it, I get constant error messages if I try to open it after installing

    Hey there Mambo822,
    It sounds like you are unable to open iTunes after installing a recent update. I would recommend the troubleshooting in the following article:

    http://support.apple.com/kb/TS5376
    Follow these steps to resolve the issue:
    Check for .dll files
    Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.
    If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
    Reboot your computer.
    Note: Depending on your operating system, you may only have one of the listed paths.
    Uninstall and reinstall iTunes
    Uninstall iTunes and all of its related components.
    Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
    Re-download and reinstall iTunes 11.1.4.
