Firefox crashes then when I try to reopen it I get a message saying it is already open and must be closed. It is not open and I cannot close it and have to reboot. It is very annoying as it happens often.

Firefox will close unexpectedly then when I try to open it I get a message saying it is already open and I must close it first. I cannot find it open anywhere and then I must reboot to open Firefox again.

Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
To install the utility, doubleclick the msicuu2.exe file you downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

I can't download the Sandy Relief album that I pre ordered. Apple sent me an email saying it was available but when I try to donwload it I get a message saying I already have, which I have not.

.Apple sent me an email saying it was available but when I try to donwload it I get a message saying I already did. I checked the store menu and it indicated that there is nothing available to download. I don't have the songs or the album showing in Itunes anywhere. Not sure what to do.

Hi OverratedBacon,
Thanks for using Apple Support Communities. I would first try downloading the songs from your past purchases by following the appropriate steps here:

If you're still unable to receive your preorder, you may want to report this to the iTunes Store:

My iTunes Library is on my computer, I have done a backup manually, and all of my music is on an external hard drive (as well as my iTunes library).

Thanks a lot Recycle bin is empty, I will move some files from the C drive to an external hard drive, then do the update, and then move the files back. Any files you recommend not moving to the external hard drive at all?

When I try to install QuickTime, I get the message "newer version is already installed". How can I do?

When I try to install QuickTime, I get the message "newer version of QuickTime already installed". I uninstalled QuickTime. I have also gone into the registry and deleted all references regarding QuickTime. I really don't want to have to reinstall Windows just to be able to install QuickTime. I have used QuickTime for years and want to use it again. What do you suggest I do?

When I open firefox I get this message; The address isn't valid The URL is not valid and cannot be loaded.

I get this message whenever I open firefox or a new tab. Anything I had tabbed to the top has gone, and the original homepage which shows all my recent visits is invalid. The full message is:
The address isn't valid
The URL is not valid and cannot be loaded.
Web addresses are usually written like http://www.example.com/
Make sure that you're using forward slashes (i.e. /).
Try Again.
Help mee!!!

Hi fredmcd-hotmail
It's not that I'm typing anything in wrong, it's when I first open Firefox or a new tab. Instead of displaying the firefox page showing my recently viewed websites it's just an invalid URL. Why would I be blocked from this page?
Thanks

When I try to sign on I get the message: Server can't be found. I have cleared cache and recent history -no luck. what do I do now?

I am on a Macbook (laptop) operating with Mac OSX 10.6.8. I am using WIFI to sign on and have no trouble opening Safari yet every time I try to open firefox I get hit with the 'server can't be found error message. Oddly, all the bookmarks still work and open fine.

This is what I did to resolve this problem. First, I uninstalled Firefox 4 & removed the Firefox folder left behind. I made sure to NOT select the option to delete personal information. Next, I backed up all of the important files on my computer. Next, I upgraded my Windows 7 to Service Pack 1, which was pending in my updates folder. Then, I went to Mozilla's website & downloaded Firefox 4 again, making sure to select only the Firefox browser and not Thunderbird too. http://www.mozilla.org/ When prompted to close any open programs, I closed Internet Explorer (which I had used to get to the Mozilla website) and I disabled my Norton anti-virus. I then completed the installation & it works just fine now. It loaded all of my personal data, such as bookmarks, it remembered my password, etc. It's fine for my needs, as I'm not a heavy user of special add-ons & plug-ins. Some of those may not work yet with the new version.

When I try to sign in, I get a message saying its already running, and I have to restart my computer each time.

I'm not sure how much more info I can give...When I go to sign on after having been on and shutting down, I get a message indicating an application of Firefox is already running and need to shut it down or restart my computer. As Firefox is not running, I have to restart my computer each time to get back on.

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles. 
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.

On a frequent basis when I go to open Firefox, I get a message saying it is already running and can't be opened. This happens on two of my XP computers. The only way I can open it is to restart the computer.

The details are in the question. I have to restart the computer to get Firefox to work a few times a week

I will try to always use "file - exit" to close it to see if that fixes the problem, but with older versions, X ing out worked OK all the time. Something may have changed with this later version.
Thank you

When I try to play stuff I get a message saying I require HDCP for playback! what's that?

So disappointed with Apple TV, just bought it and it won't work, I can use YouTube on the tv, but not from my iPad.
I can't play videos from iPad as it keeps telling me that I require a HDCP for play back. I have a top of the range HDTV set up.
Also, it only works when my iTunes is on my computer. I have set it up as by the instructions.

Welcome to the Apple Community.
I can't play videos from iPad as it keeps telling me that I require a HDCP for play back. I have a top of the range HDTV set up.
HDCP is a copy protection protocol. Content that contains HDCP protection requires that all devices are HDCP compliant, if your TV isn't compliant or isn't telling the iPad that it is compliant the movie won't play.
Also, it only works when my iTunes is on my computer. I have set it up as by the instructions.
If you mean it will only play content from your library when iTunes is running, then that is quite normal, you wouldn't expect the Apple TV to be able to read a library that isn't turned on would you.
