About every 3rd time I open Firefox, which is my primary browser, it opens in the safe mode. I then have to close everything down and restart to get it running again.

This problem has been occurring with more and more frequency. I started about 6 months ago and has happened 2 times today already. I am running windows 7, AMD Athlon II X2, and have Norton Antivrus running.

All the same FF launching itself to safe mode is pretty odd, maybe someone could lone you a keyboard or buy a cheap one to try.

'''Kill Application'''
In Task Manager, does firefox.exe show in the '''Processes''' tab?

[[Firefox is already running but is not responding]]
'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''one at a time''' until the problem reappears. '''You MUST close and restart Firefox after EACH change''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Have two users one is a test one is mine all the sudden mine lost the applications folder and now when i open my user it opens but wont respond to anything and i have to power it down and restart any clues

I have two users one is mine, one is a test i set up with apple care. Everything was working fine then i lost my applications folder icon on my user. I have been using the Finder to open applications, now when i open my user the mouse travels but i'm not able to get a respond from anything ,it's almost like its frozen. I have power off and restart and use the test user. Anyone have a clue or any ideas?

You can find the serial number either in About this Mc in the Menu bar under the , or it should be on a sticker under the foot of the machine.
If you have the install discs, try booting from them, holding down the c key and then using Disk Utility to check the drive.
You can also boot into Safe mode
To start up into Safe Mode (to "Safe Boot"), do this:
   1. Be sure the computer is shut down.
   2. Press the power button.
   3. Immediately after you hear the startup tone, press and hold the Shift key.
      Tip: The Shift key should be held as soon as possible after the startup tone but not before.
   4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
Please post back with results,
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

Everytime I open any app, my phone flashes back to the home screen! I have erase most everything off and still have this issue. I

Everytime I open anything on my Iphone, it exits whatever I have opened up and returns to the home screen. I have deleted most all of my apps thinking this would solve it. It hasnt solve anything and continues to do the same thing. I have also have hit the top button and home key at the same time to reset things. nothing has worked. Is there a app I can download to take care of this problem, or can I take it to my local carrier and they can fix whatever may be going on???

Try restoring your iphone.
Basics from the manual are restart, reset, restore.

I can't be the only one having this Finder issue: Finder stops responding and requires relaunch about every third time I open it.

I have a brand-new MBAir, but I actually noticed this starting many months ago, on my MBPro running Snow Leopard. I've repaired Permissions numerous times, run Onyx and performed all of the scans and checks (everything checks out fine), and otherwise have no problems at all with my system. It's just this constant need to relaunch the Finder, especially after downloading a dmg. In-between these episodes it seems to behave normally.
I though it was a Snow Leopard problem, and was hoping it would be gone with Lion, but, alas--no such luck.
I've searched through the discussions and support docs and haven't found anything similar--can I possibly be the only one with this weird issue? I've been a Mac User for over 20 yrs, and can't say I've ever seen this particular problem before....Does anyone have any thoughts? Thanks!

OK, Tony--did that. I noticed that it had a creation date of 2009. Wouldn't a new OS create new plist files, or do all of the old ones just migrate over from the previous OS? Interesting....
Anyway, I'll just have to wait and see if it happens again--shouldn't have to wait too long--LOL. I'll post back with an update ASAP.
Thanks for your help!

Firefox 27, XP SP3. On this new version sometimes I open it and there's no bookmarks showing. I have to shut it down and restart it. This is 27.0b1

In addition to the question above, I've never had a problem with previous versions of FF locking up, but now it locks up a lot. I believe this is a beta? I have FF 26 .exe still in a folder. Should I just go back to that version and will these problems clear up? thanks.

You can check for problems with the places.sqlite database file in the Firefox profile folder.

My pc says Firefox is running after I close the browser, and will not let me access the internet. This continues even after I shut down and restart my pc. It even continues to do it after I uninstal, then reinstal Firefox. What can I do?

We tried uninstalling , tyen reinstalling Firefox, but we still get the error message that Firefox is running, and the PC won't open the browser.
We went to the Task Manager on our PC, which said Firefox was running, and told TM to close it. But, when we try to then open Firefox, we get the same error message.

See:
*https://support.mozilla.org/kb/Firefox+is+already+running+but+is+not+responding
*http://kb.mozillazine.org/Profile_in_use
Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-make-a-new-profile
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

I have uninstalled and reinstalled and Firefox for windows 7 will not open. There is no error message--it just doesn't open, even in safe mode. What do I do?

My computer is set to auto update for Windows 7 Home Premium and for Microsoft Office Professional Plus 2010. I am also running Norton 360. There was a major update for Office on 12/10/14 that seems to be when my problems started. This month, every time my updates have caused a reboot, Mozilla has failed to open. I have uninstalled it and reinstalled it several times, and it has only lasted a day or two before it crashes again. This last time it will still not open. All the instructions to troubleshoot seem to be based on the idea that the program is open and just has issues. I can't even get it to open up in Safe Mode.
I have tried to reinstall, and it says that it will launch automatically when the install is complete, but it is not working. Since Norton scans every download before it runs, I'm not certain if that is where the problem is since I never get the window that shows the step by step installer for Firefox.
What do I need to do?

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. A clean reinstall is not the same as a regular reinstall performed using the built in installer. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from [https://www.mozilla.org mozilla.org] (or choose the download for your operating system and language from [https://www.mozilla.org/firefox/all/ this page]) and save the setup file to your computer.
#After the download finishes, close all Firefox windows (or open the Firefox menu [[Image:New Fx Menu]] and click the close button [[Image:Close 29]]).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox|here]].
WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your [[Profiles|Firefox profile]] data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See [[Back up and restore information in Firefox profiles]]. 
Please report back to say if this helped you!
Thank you.

Downloaded Firefox yesterday. Every time I open the Firefox browser, it starts in Safe Mode even though I have shut down and restarted my computer several times

I have Windows OS. I downloaded Firefox yesterday. Every time I open the Firefox browser, it starts in safe mode. I have restarted my machine several times -- Firefox still starts in Safe Mode. My favorites from IE copied to Firefox fine, and Firefox is now my default browser...it just keeps opening in Safe Mode.

I downloaded the toolbar. When I was done using the computer, I put it to "sleep." The next time I "woke" the computer and went to Firefox, the toolbar was gone. When I downloaded the toolbar again, I got a box in the upper left hand corner of the screen stating Firefox BLOCKED the toolbar, and did I want to allow it. There was NO option to allow always-it's just a one time deal. When I shut down for the day, I expected it to remain, but no-next time I fired up firefox, NO TOOLBAR. I pulled up Inbox dollars again, clicked on download toolbar, got the box stating it's blocking the toolbar, etc, etc, etc. Unless Firefox upgrades daily, or in some cases, several times in one day, I'm going to stick with my description that the toolbar magically disappears EVERY TIME I OPEN
FIREFOX!!!
I don't profess to be any type of computer whiz, I'm totally self-taught, and it's not beyond the realm of possibility that I'm doing something wrong. I've been using Firefox for about a week, so I'd welcome any help!

Adobe Reader 11.0.10 crashes on OSX 10.9.5. Crashes about once every three times when opening a file, searching an open file... started 11 months ago, reinstalling doesn't fix problem.

For about 11 months Adobe Reader performance has gotten worse and worse. It crashes about every third time I try to open a file, and frequently when I search for text strings using the find function. I have re-installed the program, I have the latest installation according to Adobe.

I've saved two files on my desktop:
f1040.pdf - downloaded from www.irs.gov - 187 KB
afmod07.2.1g.pdf - downloaded from my intranet - 1,04MB
I've powered off my PC and restarted for each file. I've opened files with double-click on them. I've encountered the same problem, when double-clicked on files in task manager two Acrord32.exe appeared, the PC was doing anything for about 10 second, after that I've encountered no activity in task manager (numbers not vary) for other 10 seconds (like freeze) and after that other about 10 seconds of loading. So after about 30 seconds the file opens with stand-alone Acrobat Reader (11.0.10).
If I retry now (after the first slow startup "of the day") the file opens in 2-3 seconds.
So:
- first open of the day or rebooting PC: 30-45 seconds
- second open of the file: 2-3 seconds
This is happening only with PDFs with forms.

This issue can be caused by an extension that isn't working properly.
Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.

Firefox will not open on my computer the majority of the time. If I shut down and restart it will work sometimes, but not always. This started recently in the last two weeks. Today is June 12th 2011.

HT1349 My iTunes keeps crashing every single time I open a Windows PC or Laptop and the "Matching with the itunes store" starts. It's driving me nuts because I can't sync to my iphones or my ipad.

My iTunes keeps crashing every single time I open the software on any of my PCs and laptops. Once the Itunes match features starts it's ony a matter of a minute or two before the software crashes. I have tons of new songs that I want to sync to my ipod, ipad and iphones but can't get it accomplished. Any suggestions??
