Why do I get 2 identical windows when starting Firefox v29?

running win7. process explorer shows only one process.

In case one of your extensions is involved, could you try starting Firefox in its Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
''With Firefox running:'' you can restart in Safe Mode using
Help > Restart with Add-ons Disabled ''(Flash and other plugins still run)''
''With Firefox closed:'' you can start up in Safe Mode by holding down the Shift key when clicking (or on the desktop double-clicking) the icon.
In the small dialog that should appear, click "Start in Safe Mode" (''not'' Reset)
Any extra windows?

Why am i getting a timedout window when i try to go to the itunes store

i'm trying to get to the itunes store... keep telling me i need to connect to internet... i'm connected but won't let me in.. Hodo i fix this??

----
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

Why am I suddenly getting the following message when starting Firefox 7.0.1, "using registry key software appdatalow\". I am using Win7 Pro 64-bit.

I had just installed a CAD package that required it to be run in compatibility mode (XP). I now get a window with the following message when starting Fierfox v7.0.1 according to the Help pull down menu and then About.

The story goes on. I am sharing this with other users for information only based on my experience with the product. I've owned a MAC since they were first introduced in 1984 and have used Norton for years. If the virus Bloodhound was real, and not just a false heuristic positive (which is totally possible) it came in on the heels of my downloading a free PDF OCR X (before reinstalling the updated version of Norton for 10.8.3) and using it to convert .jpgs > PDF OCR X text >MS Word > Adobe .pdf as that virus (Bloodhound.PDF.20 is known for exploiting weaknesses in Acrobat and Adobe .pdfs). I have never been happy having to use the MS Office suite of office products for MAC, but EXCEL on a PC is only compatibile with EXCEL on a MAC.
When I got the Bloodhound warning after running a quick scan, I ran a full scan (1,050,660 files) with the same result. I looked at my terminal - nothing happening. I called Norton, who in turn convinced me to purchase an $89.98 subscription + $19.95/month for their spyware and virus removal service (the same sales pitch I've heard from other security providers who sell services through panic). The tech, who said it was probably false, played around with my computer via remote login, and then signed off, saying everything was okay. I reran a full scan and there was the virus again. Called tech support again. Finally got the virus quarantined and tossed it. The reality is that there was a 50/50 chance that it was something because of the way MS Word was behaving when I tried to save the file created from the ocr'd jpgs (error message: disk full- when I have 250GB of free disk space). I had to resave the files with a different name and place them in alternating folders. That havoc is now gone, but I will not be keeping the subscription. Just FYI.

Why do i get the alert window when i try to email photos from iphoto?

Each time i try to email photos from iphoto i get a window with an exclamation mark over the iphoto logo. I'm guessing that the email has not been sent but why?

Go to the photo that you're trying to email and double click on it. If the resulting window has the exclamation mark that means that iPhoto has broken the file path/link to the original file.
Apply the two fixes below in order as needed:
Fix #1
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
iPhoto 8 (09) and earlier- run the options indicated
iPhoto 9 (11) and later- run Option #4 to rebuild the database
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager (iPhoto 8 or earlier or IPhoto 11 and later) and launch.
2 - click on the Add Library button and select the library you want to add in the selection window..
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the
File ➙ Rebuild Library (iPhoto 8 or earlier)
or
Library ➙ Rebuild Library (iPhoto 9 or later)
menu option to rebuild the library.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Why do I get a black screen when i click on a PDF in a web page?

why do I get a black screen when i click on a PDF in a web page? Firefox works as is should.

Hi,
From your Safari menu bar click Safari / Preferences then select the Extensions tab. If you have any installed, turn that off, then relaunch Safari. Try a PDF file.
If it's not Extensions, open a Finder window. Select MacintoshHD in the Sidebar on the left. Now open the Library folder then the Internet Plug-Ins folder. If you see any files such as this:
AdobePDF Browser or Viewer Plug-in
Move it to the Trash, relaunch Safari.

Why do I get "generic error" message when trying to upload a self-created, 1hr .wmv file?

I went through the forums and made sure that any blocks or copywrites weren't triggered by the file, it's clean and can be opened using a media player and other video editing software like windows MovieMaker. I keep getting "The importer reported a generic error" message and have no idea how to proceed. Can someone please help?

Re: Why do I get "generic error" message when trying to upload a self-created, 1hr .wmv file?
This ARTICLE starts with a checklist on setting up a computer to run PrE best, then goes into a series of links for tuning up one's computer and OS, and then links on troubleshooting.
There is also a link on posting all necessary info, to help others help you.
Without knowing much more about your system, it is impossible to say much beyond that WMV's are tough assests to work with, requiring a lot of CPU horsepower.
Good luck,

TS3694 Why am I getting error code 3194 when i try to restore my ipod?

Why am I getting error code 3194 when I try to restore my ipod touch 4th generation

This device is not eligible for the requested build: Also sometimes displayed as an "error 3194." If you receive this alert, update to the latest version of iTunes. Third-party security software or router security settings can also cause this issue. To resolve this, follow Troubleshooting security software issues.
Downgrading to a previous version of iOS is not supported. If you have installed software to perform unauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. First you must uninstall the unauthorized modification software from the computer, then edit out the "gs.apple.com" redirect from the hosts file, and then restart the computer for the host file changes to take affect. For steps to edit the Hosts file and allow iTunes to communicate with the update server, see iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store. If you do not uninstall the unauthorized modification software prior to editing the hosts file, that software may automatically modify the hosts file again on restart. Also, using an older or modified .ipsw file can cause this issue. Try moving the current .ipsw file, or try restoring in a new user to ensure that iTunes downloads a new .ipsw.
Error 3194: Resolve error 3194 by updating to the latest version of iTunes. "This device is not eligible for the requested build" in the updater logs confirms this is the root of the issue. For more Error 3194 steps see: This device is not eligible for the requested build above.

Why am I getting an error message when trying to use a template?

Why am I getting an error message when trying to use a Pages template?

You are getting an error message because there is an error.
Knowing wht version of Pages you are using, what template you are attempting to open, and what error message Pages is sending you might help determine why you are getting that specific rror message. Without those, the first sentence above i pretty much all that can be said with any assurance.
