Firefox just won't open

Although Firefox does take a long time to open on my PC; today it didn't open at all. When I tried to uninstall it and reinstall it in both wizards said Firefox was still running. I had the same problem with google chrome a few months ago.

See the details linked from [https://support.mozilla.com/en-US/questions/773934 this thread] but I think Windows & uses Ctrl Esc Shift to get task manager.
* see also [[Firefox hangs]] and [[Basic Troubleshooting]]
*Kill the process firefox.exe
* try to start in [[safe mode]]
*and if necessary rather than a complete reinstall it may be worth deleting the profiles.ini file that will create a default profile that will hopefully work ok. But first of all look at [[Backing up your information]]

Firefox just won't open. I get the little timer that indicates that something is happening but nothing ever happens, no error message, firefox just doesn't open at all. Internet Explorer opens fine and firefox opened fine yesterday.

Firefox has always worked great, no problems. Today it just would not open at all. The hourglass showed up like it was going to open but nothing would happen. I then right clicked the icon and chose open and the same thing happened which was nothing. I get no error message at all.

One of your add-ons might be the culprit. Try running Firefox in [[Safe Mode]]. If that solves the problem, see [[Troubleshooting extensions and themes]] and possibly [[Troubleshooting plugins]]

If that does not solve the problem, [http://support.mozilla.com/en-US/kb/Managing+profiles#Creating_a_profile|create a new profile]. Then, Recover your data from the old profile. See http://support.mozilla.com/en-US/kb/Recovering+important+data+from+an+old+profile

Firefox just won't open! I tried reinstalling but with to no avail. It worked well until yesterday so I downloaded new ver.5 but still it won't open. :( Please help.

See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
Create a new profile as a test to check if your current profile is causing the problems.<br />
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)<br />

I had this issue. I went to c:\program files (x86)\Mozilla Firefox\
I renamed my plugins folder to plugins.old.
It recreated the Plugins folder and all was good again. I have since reinstalled the plugins I've been prompted to install.

Installer/Application Manager just won't open

In the simplest terms: Adobe Application Manager for CS5 just won't open. It all started when I tried to update CS5 to the most recent version, but this Application Manager would freeze up after the "Initializing Installer" window was done. After that, AAM not only stops responding, but it slows the entire computer down. I would let it sit for 10-20 minutes, and still nothing. I tried downloading the patch to update AAM, but that did the same thing. I tried uninstalling CS5, but that requires AAM, so I used to AppZapper to get rid of all the CS5 programs. When I tried to reinstall, it put AAM back on my computer and the problem returned. I tried the CS5 CleanUp Utility, which claims it got rid of all CS5 files. AAM still locks up after initialization. I tried repairing disk permissions, same thing. I even consulted the PDApp.log, and there have been no FATAL or ERROR messages. I am at a loss here, as I now have no CS5 programs and no way to get them back. Please help.
I'm running OSX 10.6.5 on a 2x2.8Ghz MacPro with 32 gigs of RAM (which is why its so troubling when the computer slows to a crawl). Thank you in advance for your help.

If you are using IE 7, try removing it (reverts to IE 6). There seems to be a problem with the windows installer for QT when used with IE 7. This even holds true if you use Firefox or some other browser to download the program. Try using your
QT icon in your system tray to see if it recognizes QT being on your computer. Mine said it was not loaded even though I could find it in the Windows ADD/Remove utility. This is what I did to correct my problem.
Remove IE 7
Remove QT
Remove iTunes
Download iTunes + Quicktime
Install iTunes
All of my music came back just fine, playlists and all. You may lose some album art or settings such as compilations but that is all.

I-Tunes just won't open on my computer. How can I get I-tunes to open?

I Tunes just won't open. I am running Win7. There is no error message. It just won't open. Very frustrating. I need to get to the on line store to by a book.
If I delete I-Tunes will I lose all of my turnes? I thought to delete and reinstall I-Tunes.
Thanks for any help that is coming my way!

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox

I've been taking screen shots for years and opening them from my desktiop. Suddenly, today, I've lost the ability to open them. I can right click on the picture and do "quicklook", but that's it. They just won't open.
Similary, if I scan an image and save it as a PDF file in pictures, I'm suddenly not able to open it either!
Why?

Move the com.apple.screencapture.plist file out of /username/Library/Preferences/ to the Desktop, log out and back in, and try again.
BTW, use the default 10 point setting for text. Your choice just wastes screen space.

ITunes just won't open?

i don't know what is wrong with my iTunes. i double click on the shortcut and iTunes just won't open. then i try and click on it from the start menu, and nothing again. i have uninstalled and reinstalled iTunes about 3 times and still nothing changes. no error window or anything pops up even.
can someone help me please? thank you, i would really appreciate it.

I was having the same problem - this fixed it for me:
Remove iTunes Preference files
Some of the files that iTunes uses to store settings and preferences may be corrupt and cause issues. iTunes has two folders where preferences are saved. Move one of them to the desktop and test to see if the issue persists. If it does, move it back and remove the second folder. The location for the two preference folders are:
* C:\Documents and Settings\username\Application Data\Apple Computer\iTunes
* C:\Documents and Settings\username\Local Settings\Application Data\Apple Computer\iTunes

As a test launch iPhoto with the Option key held down and create a new, test library. Import some photos and test to see if the same problem persists. Does it?
If it does then your current library has been damaged and should be repaired: apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start
with Option #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
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 menu option.
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.

Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Since the recent upgrade from Adobe pdf plug-inn Firefox often won't open pdf-files. Uninstalling doesn't help. I don't have this problem with Internet Explorer.

Hi efacg,
Most printing issues are solved by resetting the Printing preferences. When you print from Firefox and you click on the down arrow, do you see Defualt and Firefox? Please make changes to the preferences here and preview the document.
If this continues to be an issue please also see [[Fix printing problems in Firefox]]
