When I try to reopen Firefox, it says its already running and to restart my computer or close it down. But, it isn't open. This just started when I downloaded the newest version

I open Firefox, use it then close it. Next time I try to open it, I get a message saying its already open, but, it isnt. I have to constantly restart my computer to use Firefox. What can I do to fix this?

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles.<br /><br />
NOTE: Establish a habit of exiting/closing Firefox with Firefox button > Exit or File > Exit to allow an orderly shutdown of Firefox and closing of all of the files that Firefox has open.

My computer has just prompted me to download the newest version of Itunes and now there doesn't seem to be any option to "add folder" to library, just "add file to library" so have to do one song at a time and is very time consuming!! Help?!

My computer has prompted me to install the newest version of Itunes and now there doesn't appear to be any option to "add folder to library", only "add file to library" so have to do each song individually and very time consuming....help! Anyone know if I can get this feature back? Thanks so much, Charlotte

Use CTRL+B to put the top menu bar back on screen. Add File to Library and Add Folder to Library are both under File.

When I close firefox and put my computer to sleep, the next day try to run firefox and it says its already running and I have to close it first; I have to ctrl+alt+delete to end the process and THEN start firefox.

The only other way to avoid this problem is to fully shutdown, or restart my computer.

There are other things that need attention.

If i close firefox and try to reopen it tells me its alreasdy running and I have to reboot every time??? WHY IS THIS Please

if I close FireFox and then try to open it again I get a message saying its all ready running and i must close current session and start again or reboot and I always have to reboot ?? Most frustating is there a reason for this I can change settings for

Hi Andis.
First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:
https://addons.mozilla.org/en-US/firefox/addon/3559/
Hopefully this will help.

I upgraded to the new Numbers, but when I try to open an edited spreadsheet, I get this: "You need a newer version of Numbers to open this spreadsheet. You can download the latest version of Numbers from the Mac App Store." Help!

When I check for upgrades, my computer "No updates available" and says "OS X Update Version 10.9.2 installed Mar 9, 2014."
When I go to the app store to get the new Numbers, it says "installed".
I shut down and rebooted my computer, but I still get the message that says I need new Numbers to open the spreadsheet that I want to open. I can open other spreadsheets, those all work. I just can't open the one I want. Please help. I need the data on that spreadsheet TODAY!!!

Hello CLynas,
The following article provides steps that can help get your documents to open with the correct version of Numbers.

It would appear that the corrupted script files are sessionstore.js or prefs.js.
these i found in Application Data/Mozilla/Firefox/Profiles/2xewu6aw.default folder

Check and tell if its working.

Firefox says it's still running eventhough I've closed out of a site and will not allow me to open another site. It says "Firefox is still running". I have to completely re-start my computer. It started after I downloaded the newest version.

I log onto an email account and when I'm finished I log out and wait a few minutes before typing in a URL address for a site.
Since downloading your version 6.0.1, I have had this problem. I have to completely re-start my computer.

My Mac does not recognize that I have downloaded the newest version

I continue to get the error message that I cannot open a pages file until I download the newest version. I have downloaded the version. The apple store recognizes that I have downloaded the version and yet, pages will not open the files.
What next?

You have 2 versions of Pages on your Mac.
Pages 5.2 is in your Applications folder.
Pages '09/'08 is in your Applications/iWork folder.
You are alternately opening the wrong versions.
Pages '09/'08 can not open Pages 5 files and you will get the warning that you need a newer version.
Pages 5.2 can open Pages '09 files but may damage/alter them. It can not open Pages '08 files at all.
Older versions of Pages 5 can not open files from later versions of Pages 5.
Once opened and saved in Pages 5 the Pages '09 files can not be opened in Pages '09.
Anything that is saved to iCloud and opened in a newer version of Pages is also converted to Pages 5 files.
All Pages files no matter what version and incompatibility have the same extension .pages.
Pages 5 files are now only compatible with themselves on a very restricted set of hardware, software and Operating Systems and will not transfer correctly on any other server software than iCloud.
Apple has removed almost 100 features from Pages 5 and added many bugs:

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

I haven't been on iTunes in awhile i downloaded the newest version and now when i sync i try to sync my iPhones library to iTunes Library and says i will lose all music on iPhones library

I havent been on iTunes and synced up on my laptop for a couple months so i get hooked up on wifi and download the newest version of iTunes and sync up to it and none of my songs are in the comp library.everytime i try to sync my iphones library to the itunes library it says i will lose all songs on iphone.so i'm trying to figure out what i need to do to get the library from my iphone to my itunes library on my laptop!!

Plug in your iPad and hit sync. It should transfer your purchases. Or go under the purchased option in iTunes store and download your purchases. Connecting the iPad is easier.

I downloaded the "newest version" of Firefox. Now when I try & open FF, I get "Your computer must be rebooted." I have rebooted 7 times & still can't get in.

I got a message that the version of Firefox I was using was outdated, so I downloaded the newest version.
Now when I try & open Firefox I get the message, "Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now?"
I have rebooted my computer 6 times & get that same message every time and still cannot get into Firefox. Has anyone else encountered this or know the solution?

Hi Dann, did you delete to the Recycle Bin, or did you do a more drastic permanent delete (e.g., Shift+Delete) or empty the Recycle Bin?
''If you think it might be in the Recycle Bin:''
First, make sure hidden folders are viewable. You can do that using Windows Explorer or My Computer > Tools > Folder Options > View tab. Look for the radio buttons to show or not to show hidden files and folders.
Now look for C:\Documents and Settings\''username''\Application Data\Mozilla\Firefox\Profiles or some part of that path, or your actual profile folder, which would have had a semi-random name, typically ending with default, or the bookmarkbackups folder, which is the ultimate prize.
''If it's not in the Recycle Bin:''
To recover your old Firefox settings folder (profile folder), try using a utility like Piriform's Recuva:
http://www.piriform.com/recuva
That needs to run ASAP before deleted files are overwritten.
The folder you're looking for would have had a semi-random name, but be located here:
C:\Documents and Settings\''username''\Application Data\Mozilla\Firefox\Profiles
By default, that folder is hidden. Make sure hidden folders are viewable. You can do that using Windows Explorer or My Computer > Tools > Folder Options > View tab. Look for the radio buttons to show or not to show hidden files and folders.
In particular, a bookmarkbackups folder would be a wonderful thing to be able to recover.
Hopefully one of these methods will work for you.

This month I downloaded the newest version of PAGES. Now when I try to open the documents made with this program it says "You need a newer version of PAGES to open this document." I go to the App Store and says it has downloaded. What to do?

You can add the icon of the missing Pages on your Dock or open Pages from the Apple menu > Recent Items list.
Or you can archive Pages 5 so that it doesn't automatically open.
If you are unhappy about this review/rate Pages 5 in the App Store.
