I am trying to open my iTunes on a Windows XP laptop and get the error message 42404 "iTunes application could not be opened. Please repair or reinstall QuickTime". I did that and it did not help. Any ideas?

Let's see if a more rigorous uninstall/reinstall procedure gets us past that, nancy. See the following troubleshooting document:

Did you downgrade iTunes? What version is listed in Help> About iTunes?
If you don't have iTunes 10.5.2, download it from here -> http://www.apple.com/itunes/download/
If you have iTunes 10.5.2, try re-creating your iTunes library.

Why, when I open Firefox 4, do I keep having Firefox 3 pop up continually and having the error message "A copy of Firefox is already open. Only one copy of Firefox can be open at a time." ?

Every time that I try to use Firefox 4, Firefox 3 pops up on the Dock and tries to start up. I get the error message "A copy of Firefox is already open. Only one copy of Firefox can be open at a time." I click OK and the message goes away. Then it happens again. And again. It doesn't stop until I quit Firefox 4. I've tried creating a new profile (and deleting my old one) and deleting the .parentlock and the profile.ini file, but nothing works. Help me please!

Hi, I may suggest to activate the root account and try the uninstall process from that account. To do so, you have to:
Go to System Preferences a open up the Users pane;
On the left side of the pane, you shuold see Login Options;
Enabled editing option clicking on the lock (it will ask your password);
Once the pane is enabled, you should see something like Server Account Network (sorry my OS is in italian, so I don't exactly know the right translation), and right next to it a button;
Click on that button, and a new pane shows up. Click on Open Directory Utility, and on the upper bar of OS X click on Edit;
Select Enable Root Account (you can set a password, or not);
Done that, you should log out and when the login window show up, type on the user field "root" and the password you choose;
Theorically, from this account you will be able to unistall the application.
After completing your task, I reccomend you to disable the root account, just by loggin in your personal account and repeating the steps I described before. Hope it helps

This article has a link for more information on finding your profile directory: [[Fix the "Could not initialize the application's security component" error message]]. On Windows 7, you can try this (either in a Windows Explorer window address bar or from the start menu search box):
%APPDATA%\Mozilla\Firefox\Profiles
You may see one folder in there and that's the one you want. If you see more than one, look for the one with the most recently modified files.

TS1424 when i try to get on my itunes account i get the error message "New itunes library" and i am unable to open my account.

I have had an itunes account for over a year and have always used the same computer. Recently I have been unable to open my itunes account. Every time i try to open it, the error message "New itunes Library" comes up and I can do nothing further. Does anyone have any ideas what I can do to resolve this issue.

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

On win 7 64 bit mozilla or IE 10 I get the following message This installation package could net be opened verify that the package exist and that you can access for contact the application vendor to verify this is a valid windows installer package I trie

If you are not already doing so, install from an Administrator account.
If you haven't already done so, download the iTunes Installer from:
http://www.apple.com/itunes/download/
Then right click on the installer and select "Run as Administrator." (Even though you are using an admin account).
If that doesn't work, try creating a new administrator account and installing from there.

I get the error message "unresponsive script" when I try to open Firefox, and then I can only delete the message by going to Task Manager.

After I downloaded the Firefox update, when I tried to open Firefox I got the error message: "Warning unresponsive script...etc". This happens every time and the choices in the message ("continue" etc) are unresponsive. Further I can't delete the error window without going to Task Manager to end the program. The problem also disabled Internet Explorer which will now simply not load. Google Chrome is working. I assume it relates to the update since the problems (for both Firefox and IE) occurred immediately after the download.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
