We usually advice first to Reload web page(s) and bypass the cache in case of such problem and then do a check for extensions to see if any are causing the problem.
* Press and hold Shift and left-click the Reload button.
* Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
* Press "Cmd + Shift + R" (MAC)
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

  • Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight etc. It was fine before the upgrade and I have all the system preference set to "never turn off"

    Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight (cd's  / recording etc. It was fine before the upgrade and I have all the system preference set to "never turn off" - Help !!!

    Good advice from Linc Davis that should sort out your query i think...
    However you dont want to set your MBP to never go to sleep...
    Adjust reasonable sleep settings...
    And the download an APP called caffiene...
    When you click it you can have your MBP never go to sleep with a single click of your menu bar... and with another click it can go to sleep normally to maintain the laptop...
    Simply click the cup... To toggle never sleep/sleep

  • I have lost the system preferences application. How do i restore it?

    Hi,
    I have lost the system preferences application. How do I restore it?

    If you have had Time Machine running on your computer, you may be able to get it back from a backup.
    However, since System Preferences contains more than just the application (it also contains modules that are kept in [$HOME]/Library/PreferencePanes on your startup disk), then you may need to restore them too if they do not exist on your system either.
    Granted, having a missing System Preferences could be disasterous... at the least, you can't set your preferences, but at the most, system services (whether Apple or 3rd party) could be broken.  Because of this, the above advice is not guaranteed.
    The only sure-fire way of getting your System Preferences back is to re-install your system.
    Important note: TheDave413's note about the Dock is also a very useful tip, since the Dock keeps an alias of the System Preferences app rather than a copy of it.  If that is all that's missing, you can easily re-create it yourself without any of the above drastic action!

  • Some how I have deleted the system Preferences application. I had already deleted everything from the trash bend before I realized system pref. was deleted. How can I recover or get it downloaded?

    Somehow I have deleted the system Preferences application. I had already deleted everything from the trash bend before I realized system pref. was deleted. How can I recover or get it downloaded? Everything has been transferred to my new mac pro, but would like to give this old mac to son-in-law.  Can I download system preferences back into this old mac?

    How Restore Deleted or Missing OS X Components
    A few of the basic OS X installed applications can be restored from the Optional Installs installer located in the Optional installs folder on your Installer DVD.  However, if what you need is not there then follow the instructions below.
    How to Use Pacifist to Restore Deleted or Missing OS X Components
    Insert the OS X Installer DVD into the optical drive.  Use a simple utility like TinkerTool to toggle invisibility so you can see invisible items.  Alternatively, open the Terminal application in your Utilities folder and at the prompt enter the following:
    defaults write com.apple.finder AppleShowAllFiles Yes
    Press RETURN.
    To turn off the display of invisible files repeat the above command substituting No for Yes.
    The install packages are located in the /System/Installation/ folder on the DVD.
    Download the shareware utility Pacifist. Use it to extract a fresh copy of the missing item(s) from the file archives on your OS X installation DVD. The file archives are in the /System/Installations/ folder (use Go to Folder option in the Go menu of the Finder.)
    Here are Four Basic ways to use Pacifist (courtesy of George Orville.)
    Drag a .pkg icon onto the Pacifist window .....proceed to step 7.
    Click on “Open Package ....” and navigate to package desired and click “Open” in the open/save window.....proceed to step 7.
    Insert Mac OS X installer CD and when it mounts, navigate to .... Menu->Go->Go to Folder. In the path field enter or paste ....
    /Volumes/disc name/System/Installation/Packages (where disc name is the name of the CD/DVD that you inserted.)
    Click on the  "Go" button ..... • Drag a .pkg to Pacifist..... proceed to step 7.
    The package you'll need will have to be discovered by trial and error, but for most applications you should start with the Essentials.pkg and/or Additional Essentials.pkg.
    D. Insert your Mac OS X install disk 1 .... and open Pacifist.
    1.          In Pacifist, select "Open Mac OS X Install Packages" ... dialog may appear asking for disk 2, then disk 3 and finally disk 1 again.... {if DVD is not used)...If “Stop Loading” is selected...the procedure will stop!!!
    2a. When loading is complete, a new window appears, click the triangle to display contents of each package...Select item and proceed to step 7.
    2b.          or click the “Find” icon in the Pacifist window and type the name of the software you need.
    3.          In the list that comes back, click the top most entry for the item that you want. ..... that is the one for the English language.
    4.          On the top of the Pacifist window, click “verify” .... you will probably be prompted for your password.
    5.          Enter checks for.... “verify permissions” and “verify file contents.” and click “verify” ....enter password when prompted.... you will get back output which may look like this:
              20 files were scanned. 20 of 20 files were present on the hard disk. 0 of 20 files had file permissions that did not match those specified in the package. 0 of 20 files had checksums that did not match those specified in the package.
    6.          Click “close”. Go to step 7.
    Extract or Install........
    7.          In the Toolbar (upper left), you now have the option to extract or install. Click a file in the lower list and those two icons will be enabled.
    8.          If “Extract to...” is selected.... navigate to the location where the file will be placed, select “choose”, select “extract” in new dialog that appears,authenicate , if prompted, click “OK”.
    9.          In the next dialog, click “Extract”.
    10.          If “Install” is selected... dialog will appear with the location/path of the installed software. Click “Install”
    11.          Type in your password, click “OK”
    Pacifist will begin to extract files.
    12.          In steps 8/10ß.... you also have the choice to “cancel”
    Notes:          Pacifist may find that a file it is installing already exists on the hard disk. Pacifist will present you with an alert panel....
    Stop
    Leave original alone
    Update .....
    Default selection
    Replace .... (Replace option should only be used on full install packages)

  • HT2490 my desktop and screen saver option is no longer available in the system preferences. meaning it is no longer listed. how would i go about getting it back?

    my desktop and screen saver option is no longer available in the system preferences. meaning it is no longer listed. how would i go about getting it back?

    If you used system cache cleaning software it can mess up Apple software.  Stop using such software.  Remove Mackeeper if present using these directions:
    https://discussions.apple.com/docs/DOC-3691
    If you started typing something in the search field of the System Preferences, it might be hiding.   Quit and reopen System Preferences to be sure it isn't hiding because it is searching for another panel.
    Lastly, if none of the above apply, go to your hard drive -> System -> Library -> PreferencesPanes folder and see if it is hiding there.  If it isn't, get your 10.5 installer disc that installed 10.5 on your Mac, and restore it with http://www.charlessoft.com/ 's Pacifist, and then run the 10.5.8 combo update to ensure the version matches the operating system.

  • I have lost the system preferences settings icon and want to reinstall my os  to orig settings unfortunately I have lost thrown out disc due to moving house, can i get a copy of hardware drivers as can buy os disc

    Can anybody help I have no problems duyinng new os system,
    but unable to find which hardware and drivers required for system to work

    All hardware drivers are included with the Operating System, OS X.
    You will need the Original system discs to Reinstall the OS clean. You can get them from Apple for a fee. So call Apple and have the serial # of your Mac and order the Replacement System Discs. And this time try not to lose or throw them away.

  • TS1468 itunes is a joke.  Many of my songs are either separated into single albums when it is a compilation or are outright missing without a trace.  They did this with their crap software and the solution?  I have to go thru an manually group them...sure

    Now I find that my audiobook of WWZ is also nowhere to be found.  You have to practically promise your firstborn in order to get a new computer authorization key...I've just had it, and they keep making it worse. grrrrrrr.  Any idea on how to get itunes to put the albums back together into a single album again?

    one last thing: I'm also getting this problem here too:

  • This is a question for all my adobe applications in the CS6 suite. How do i manually update them? I have not gotten any updates in about 6 months and they are running really slow. I really think this is the issue. How can i do this?

    I am a full sail university film student and I need all my adobe applications running strong. Everything is running slow and sluggish. I think this might be the issue. Does anyone know how to manually update the adobe Cs6?

    What does your computer's sluggishness have to do with any potentially missing updates? That's pretty much nonsense. The last AE update was the 11.0.4 one from November, anyway, and it's only relevant for Mac people more or less. Whatever issues you have have nothing to do with that but rather poor system configuration and maintenance - fragmented cache disks, disks almost full with temp files, too many other processes/ programs running and gobbling up resources, aggressive external tools like virus scanners blocking access to files and functions and so on. Really, you are completely looking in the wrong place. Bring your computer up to speed and AE will run a lot better.
