Firefox does not start at all, cpu usage is 100%

I have tried installing different versions of Firefox, but all of them have the same issue - the browser does not start at all, no error messages, cpu usage is 100% in task manager, so have to shut it down there.

Firefox does not start at all

I cannot use Firefox at all now. It simply will not start up. I've been through the troubleshooting section and it appears something was corrupted when it closed. However, the advice to create a new profile can't help either as it won't let me.
I have various saved information for websites which I don't have to hand elsewhere, so really need Firefox to work. Is there any way of solving this?

[solved]firefox does not start anymore: (firefox:4358): Bonobo-WARNING

Hi All,
Firefox has always worked on the laptop of my girfrind, until yesterday. When I run firefox from the command line I get the following message, and firefox does not start.
ingeborg@laptop:/storage/home/ingeborg$ firefox
(firefox:4358): Bonobo-WARNING **: Bonobo must be initialized before use
ingeborg@laptop:/storage/home/ingeborg$
Versions:
ingeborg@laptop:/storage/home/ingeborg$ firefox -v
Mozilla Firefox 3.6.12, Copyright (c) 1998 - 2010 mozilla.org

When I move .mozilla, firefox starts without problem, so there must be something wrong with the information in ~/.mozilla:
$ mv .mozilla/ .mozilla-moved
ingeborg@laptop:~$ firefox
(firefox:4852): Bonobo-WARNING **: Bonobo must be initialized before use
(firefox:4852): Bonobo-WARNING **: Bonobo must be initialized before use

Any Idea's how I can figure out what file is causing this problem in .mozilla?
What does code 4358 and 4852 from firefox mean?
Best regards,
Cedric

I have reproduced the problem:
1)Move (or remove) ~/.mozilla
2)goto this website : http://toolbar.zynga.com/install/farmville/
3)login with a valid facebook acount
4)Click install, and then click allow, install now, restart namoraka, restart, finish, and then click save and quit.
Now firefox does not start anymore.
Is it usefull when I make a tar file of .mozilla and post it here?
Best regards,
Cedric

Firefox does not start up after an automatic update. Every time i try to open it, it just prompts the Mozilla Crash Reporter.

Same thing happens when i click restart.
No difference when i run it in Safe mode. And it won't let me create a new profile either. Is there anyway else i can extract my bookmarks? This is driving me crazy!

Did the crash reporter send any crash reports? 
You can see the crash reports in this folder:
"C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Crash Reports"
See: http://kb.mozillazine.org/Breakpad
See also [[Firefox crashes when you open it]]
Create a new profile as a test to check if your current profile is causing the problems. 
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]] 
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" 
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) 
See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox 
If that still causes the same problem then do a clean reinstall and remove the Firefox program folder.
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* 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.

My firefox does not start even though i created a new profile.What is the solution?

My firefox does not start and when i debug, its showing a win32 exception error. what should i do?

See:
*https://support.mozilla.org/kb/Recovering+important+data+from+an+old+profile
*http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
You can also update to Firefox 9.0.1

Firefox does not start by clicking on the icon in RHEL 5.

Firefox does not start by clicking on the icon in RHEL 5 on thin clients, also the internet proxy server usename is not accepted for java applets on webpages. However while using Firefox on the servers directly everthing works fine. This issue occurs on a server thin client environment, where the home directories are located on a 5 TB storage connected using SAS cables to the servers.

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.
See [[Server not found]] and [[Firewalls]] and http://kb.mozillazine.org/Firewalls

even in safe mode when it is supposed to start it stil hangs and no window is oppened...
this happened when i updated to firefox 2.0.0.4...
Make sure firefox is actually stopped (check "ps axww" output for it). Kill it if it's still running somewhere.
Check your firefox profile area for files named "lock" and ".parentlock". Delete them if you find any.

ITunes does not start at all!!!

ITunes does not start at all this morning. ( I have a MacBook). I never got this problem before.
What to do?? I restarted my PC already and nothing happens.

Sorry, it is starting, but not playing!!!!!!!!

Firefox will not start at all ... not even profile mananger will start

After an auto overnight reboot initiated by a Windows update (XP 5.1 SP3) Firefox will not start at all ... not even Profile Manager ... all that happens is a few seconds of hourglass on the cursor and then nothing ... this is happening on two different computers at the same time ... identical symptoms ... any advice?
== After overnight reboot by auto Windows update

I had the problem after I restarted the computer when Firefox indicated that was needed to install updates. After that every attempt to start Firefox resulted in no response at all. I went to my program list and found Firefox Safe Mode. That started OK. I then closed it. After that Firefox started OK.

Ovi Suite does not start at all

Hi folks,
I just finished the installation of the Ovi Suite, but when I dbl-click on it
or start it via Start - Programs... it does not start at all. There is that error
message in the event log:
18/07/2010 20:55:01 (OviSuite) - ERROR - DAL_Plugin_PCCS, Thread 10, Line 168, .\Application\CDalPCCSDevice.cpp, CDalPCCSDevice::getHandle(): DAL failure detected: (102) converted from PCCS error [0x80100023: Device do not support operation] / DA_OpenCA / @ CDalPCCSDevice::getHandle (.\Application\CDalPCCSDevice.cpp:168)
Anyone with an idea what could be wrong?
The Nokia PC Suite works e.g. for contact entries (but doesn't seem to work for the latest maps stuff).
Thanks,
roveda

Hi,
I am not sure this will solve your problem but you can try this once.
1. Uninstall Ovi Suite, PC Connectivity solution and Nokia Connectivity cable drivers from Add/remove program if anything is there.
2. Delete the files from here If anything is there
C:\Documents and Settings\User\Application Data\Nokia\Ovi Suite
C:\Documents and Settings\user\Local Settings\Application Data\Nokia
C:\Documents and Settings\All Users\Application Data\OviInstallerCache
3. Restart Computer.
4. Download and Install latest OviSuite http://europe.nokia.com/support/download-software/nokia-ovi-suite
5. Restart Computer
6. now run NOS

Have you tried a reset by pressing and holding the sleep/wake button and the home button for 10-15 seconds until the Apple logo appears, ignore the red slider. Then turn back on. You won't lose any data doing the reset.

Firefox does not open at all since I updated to version 3.6.4, not even when I re-download it.

Firefox crashes (does not open at all) since I updated to version 3.6.4. Not even when I re-downloaded it several times. Now, even the old version doesn't start. I have a Mac OS X version 10.6.4. It doesn't show that pop up window that explains why it crashed. It just stops and quits.

Hello everyone.
Hopefully this support article is what you need:
https://support.mozilla.com/en-US/kb/Firefox+will+not+start
In any case, you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

Can I get rid of 36? It installed an update and now firefox does not work at all

firefox 36 is seriously broken
It updated on my computer and now does not work at all. I've tried all the suggestions and no help.....going back to IE

Hi wskossack, I am sorry to hear that you are having problems with Firefox 36. I am also sorry that we have not been able to get that working for you yet.
If what you really want is to uninstall Firefox we can do that. Of course I have to ask if you would be willing to let my help you to get the most up to date version of Firefox working. But, Firefox is all about the ability to customize. If you want we can install the last version of Firefox and you can use that until the next version comes out or while we work to get Firefox 36 working for you. I will try to cover every option in my reply.
First I will cover uninstalling Firefox. If you want to look at the [[Uninstall Firefox from your computer|article click here]] this can be done in about 7 steps
I would recommend that you completely uninstall Firefox and install it again. This will most likely fix any problems you have right now. Because you are asking how to do this I am going to assume that you have not tried this.
If you have Vista or Windows 7:
1) close any open Firefox windows.
2) from the start menu click on control panel
3) click on uninstall a program
4) from this list chose Firefox
5) click on uninstall (this is located turds the top)
If the Uninstall Wizard does not run, you can start it manually by running helper.exe, which is located in one of these locations by default:
(32-bit Windows) C:\Program Files\Mozilla Firefox\uninstall\helper.exe
(64-bit Windows) C:\Program Files (x86)\Mozilla Firefox\uninstall\helper.exe
6) in the Firefox uninstall wizard click next and on the next page click uninstall then click finish
7) to remove other files and folders that may not be removed by the uninstall, you must manually delete the Firefox installation folder, which is located in one of these locations by default:
(32-bit Windows) C:\Program Files\Mozilla Firefox
(64-bit Windows) C:\Program Files (x86)\Mozilla Firefox
The uninstaller does not remove any user data such as history or bookmarks. To completely remove this data, you must manually delete the Firefox folder containing your user profile:
Click the Windows Start button.
Type %APPDATA% in the search field and press enter to open the hidden Roaming folder.
Open the Mozilla folder
Delete the Firefox folder.
Now I am going to go over how to get the last version of Firefox installed on your computer. If you want to look at the [[Install an older version of Firefox|article click here]] . If you decide that this is what you want to do please look at the article for some impotent security information.
Firefox 35.0.1 was the last version of Firefox and you can get it by [https://download-installer.cdn.mozilla.net/pub/firefox/releases/35.0.1/win32/en-US/Firefox%20Setup%2035.0.1.exe clicking here] . The link is also in the article. If you do this you will have to disable the auto update. To do this go to options, then go to advance. Under advance there will be a sub tab. You want to go to update. Then you can select to never check or to have it tell you when there is an update.
So the only thing left is for me to help you with any problems you are having with Firefox 36. I hope you will give me a chance. In any case, if you need any more information or help with anything that I went over please let me know.

Firefox does not start at all, cpu usage is 100%
