I REINSTALL 10 TIMES SO DON'T TELL ME THAT!!!
I'm piss because i need firefox working again so i can finish reseaching my speech in 5 days.

Which files do you have in the defaults\pref folder in the Firefox program folder?
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
See also "Other solutions":
*http://kb.mozillazine.org/Preferences_not_saved
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 22.0: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

There should be nothing native to the OS X which would ask for a password
or other information on a restart, unless accompanied by the traditional login
box with your user name.
There are adware or marginal products that could be called malware (bad)
that would impose their presence and some items that could have been
downloaded by accident or through some corrupted free software site; of
those some could ask for and gain permission to go through your Mac
and maybe even run in the background to do other nefarious misdeeds.
You could see if startup in SafeBoot allows you access past that the Completer.
Since I don't have a pile of helpful article links on how to resolve various issues
I'd be looking them up one way or another.
There are some helpful items in the site http://thesafemac.com - see Tech Guides
listed (adware, malware, & performance) plus a link to the adwaremedic page.
Also, Apple support has a helpful page on how to remove adware and other bits:
•Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support
Hopefully this helps somewhat.
Good luck & happy computing!

Photoshop Elements 11 will not open. It gives an error message about a missing part of the program.

I purchased a new HP Envy running Windows 8, with Photoshop Elements 11 preinstalled. When I clicked on the icon the program would not open. It gave an error message stating part of the program was missing. The error message was in code and stated some parts of the program needed to run togeth, or side by side. Am I able to download a repair patch from Adobe customer support?

Could you please attach a snapshot showing the error dialog?

Which Fx version? When you uninstalled Fx, did you reboot computer before reinstall?
Also, check for / delete any leftover files in the Fx programs install folders, before reinstall?
Is your profile in the default location or custom location?
Have you tried creating a new, completely clean profile - to test (then make sure to select that profile to start Fx - from the Profile Manager)? (no addons or plugins installed).
Does the user acct (that Fx fails under) have access ("rights") to all locations - especially for Fx profiles location?

I am trying to activate new qualitative research software. When I attempt to activate it my Apple Air will not allow it and gives an error message saying we cannot verify the identity of the developer of the software

I am trying to activate new qualitative research software. When I attempt to activate it my Apple Air will not allow it and gives an error message saying we cannot verify the identity of the developer of the software

The developer isn't recognized by the App Store, so your Mac is trying to protect you in case the program is malware. As long as you are sure it isn't, follow this procedure:
In the Finder, locate the app you want to open.Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.
Press the Control key, then click the app icon.
Choose Open from the shortcut menu.
Click Open.The app is saved as an exception to your security settings, and you will be able to open it in the future by double-clicking it, just like any registered app.

ITunes 10.6.0.40 will not open on Windows 7, no error messages come up. Have tried un-installing it and re-installing it many times.

iTunes 10.6.0.40 will not open on Windows 7, no error messages come up. Have tried un-installing it and re-installing it many times. Please help.

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If the advice above doesn't resolve things you could try this alternate version:
iTunes 12.1.0.71 for Windows (64-bit - for older video cards) - itunes64setup.exe (2015-01-28)
which is a 64-bit installer for the 32-bit version of the core application, similar to previous 64-bit releases.
Or roll back to the previous build:
iTunes 12.0.1.26 for Windows (32-bit) - iTunesSetup.exe (2014-10-16)
iTunes 12.0.1.26 for Windows (64-bit) - iTunes64Setup.exe (2014-10-16)

CS4 won't start up on my new computer. The error message I get is "Licensing for this product has stopped working."

CS4 won't start up on my new computer. The error message I get is "Licensing for this product has stopped working." Both the old and new computer are MACs and the error code I get is 150:30. It says to restart the computer or open another application in the suite, but neither helps. It says if nothing helps to contact Adobe support, but this is the only way I'm given to contact adobe support. Can I really not use my purchased software on my new computer? What do I do to activate the license on the new computer?

I've deleted Adobe Reader 11 and rebooted and reinstalled Adobe Reader 11 and I still get the error message that 'Adobe Reader is blocked because it is out of date'. Using Windows XP with the latest updates (SP3).

Google Chrome is a problem:
if you use Chrome's own PDF viewer, the results are unpredictable.
if you use the Adobe Reader plugin with Chrome, it may reject (block) it if it is not the latest version. Reader 11.0.08 is the latest version for Windows XP, but Chrome may insist on the current version 11.0.10.
My suggestion; use a different browser!
