Firefox 4.0 will not open at all. It shows that the process is running in the task manager but will not open the window even after closing the prcess and restarting.

I have had firefox since an earlier 2. version and have been able to upgrade as normal. After the installation is done it will not open at all. I have restarted and even uninstalled all previous version .exe and still nothing. I am using windows 7 OS. I am still running 3.6.8 and would love to see the new one running on my laptop.

hello, this crash is caused by Websense Endpoint security software that is running on the system. please try to install all the updates for this program that are available...

Firefox opens in task manager but does not display.

This morning my Firefox stopped working and I had to end task. Afterwards when trying to restart Firefox the firefox process will open under task manager but nothing displays on the screen. I've tried ending all firefox processes and restarting my pc. I also tried creating a new profile under the firefox,exe -manageprofile command. When I created the new profile and ran under it I had the exact same problem. I tried running under safe mode and I get the pop up telling me that mozila is running under safe mode with the check box's for clearing settings but there is still no window displayed and when clicking continue in safe mode the pop up box goes away and I'm left with nothing once again. I tried running the firefox setup freshly downloaded in an attempt to repair the setup of sorts but this had no effect.
I also did a short search of the forum for any soloutions but so far haven't found anything. If anyone could suggest some more things to try before I do a complete wipe of Firefox using CCleaner.
Also in the event I use CCleaner I'd like to back up my bookmarks first so if anyone knows a start parameter to back up bookmarks or even what file the bookmarks are stored (already found a forum topic on the saved passwords file) in and if copying that file into a new installation will work please let me know.
Regards to any one who can assist.

I had this problem for a couple weeks as well and it was extremely frustrating considering we use firefox for all our company tasks. Here is the solution:
First of all if you have no bookmarks you want to save, then go directly to step 7. If you want to save your bookmarks first, then follow these steps.
1. Shut down the computer
2. Reboot and open firefox
3. Go to Task Manager, right click firefox.exe, and click END PROCESS TREE
4. WAIT 30 SECONDS! Then Double-click the shortcut to try and open firefox again
5.Repeat steps 3 and 4 until firefox finally opens (trust me, eventually it will)
6. Once it finally opens, backup your bookmarks,
7. Download a copy of firefox from there website
8. Uninstall from programs menu and make sure to check the box REMOVE ALL COMPONENTS
9. install the new copy and BOOM! it works
If it doesn't work, you're an idiot. If you don't want to reinstall firefox, then you're out of luck. Good Luck!

Firefox opens according to my task manager, but will not appear on my desktop.

My windows XP computer refuses to show Firefox on my desktop. Task Manager shows firefox.exe active and using about 43 meg of memory. I have tried Firefox 4 and Firefox 3.6.
Using XP sp3 on this computer. Have scanned using Avast AV and Malwarebytes. I have 4 gig of memory on this computer.
I do not receive any error messages.

Could be a problem with your Firewall. Eliminate all references to Firefox and Plug-in container. The Firewall should ask for permission and re-set if Firefox starts. Try disabling Firewall and Anti-virus briefly.
Try starting in Safe Mode - Hold Shift key down as you double click on your Firefox desktop icon> don't check anything on the page that opens>Continue. Actually this is probably the best place to start.
If Fx works in Safe Mode you probably have a problem with one of your extensions or a conflict. Remember that all sorts of things have been up-dated as well as Firefox.
Along the way make sure your Plug-ins(like Flash) are up-to-date.
Be suspicious of third-party toolbars and try disabling them.
This won't be the specific problem but if you get Firefox going you should try disabling Hardware Acceleration to see if it runs better - Options>Advanced>General>browsing>uncheck "Use Hardware Acceleration . . . If it does run better you should update your graphics card.
This is the standard troubleshooting you may have to work through -
https://support.mozilla.com/en-US/kb/Troubleshooting%20extensions%20and%20themes
Another suggestion you may get, certainly when all else fails, is to download a new full Firefox installer to your desktop. Uninstall your old Firefox, don't delete your preferences etc; and then install your new Firefox.

Firefox is running in lower task bar but will not open on desk top.

I click on the desk top short cut and the fire fox symbol shows up in the lower task bar and task manager shows firefox running but it isn't running on the desk top.

In the Task Manager, make sure to check both the Applications tab and the Processes tab. On the Processes tab, Firefox may have two different components running: firefox.exe and plugin-container.exe. Well, in 3.5.11, it would be only the first one.

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.

My itunes will not open. It shows to be open in Task Manager but will not open.

I have tried the Quicktime Fix that was recommended but it did not help. I also cannot shut down the itunes process in Task Manager.

Doublechecking. Have you worked through the following troubleshooting document?

Firefox shows in task manager, but won't open

Firefox doesn't open, though it opens once in a while. It shows in task manager and takes up 50% CPU usage, and ending process and retrying doesn't work. Profile manager doesn't open either. There's no error message, and have restarted laptop (Windows XP) many times, but no results.
Help would be appreciated!

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. 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 http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#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
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#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.
Please report back to see if this helped you!

ITunes 11.1 running in Task Manager but does NOT Open

I have looked areound and no one seems to be having this problem (that I can tell).
My problem started when I upgraded to iTunes 11.1 running Windows 8. When I tried to open iTunes, it never opens but if I open the Task Manager I can see it running (32-bit) with a couple other Apple programs. I have downloaded with both Firefox and Chrome.
I have tried the following things:
Completely uninstalled iTunes following the steps outline by Apple (included checking all folders for files). Same thing happened when I re-installed.
Tried to install as the Administrator.
Tried to run using Windows 7 compatibility
Refreshed my computer (erases and resets everything minus personal files) and installed iTunes 11.1 before anything. Did not work.
Once or twice it would open but as soon as I closed and tried to re-open iTunes, same thing. Never opens but running in Task Manager.
I have no idea what to do next and am running iTunes 11.1 on an OLD desktop that is not sustainable.
Thanks in advance.

Black window remains open even after closing the window programatically

I have an application which has multiple windows. From mainwindow button click event I am closing the child form of the application. The child window is opened after a successful socket, serial or gateway connection attempt, after which the application
do work with some threads and while clicking on a button on mainwindow I am closing this child window after disconnecting the respective connection mode. But after the close event the child window background gets black and it remains open unless and until
I just do a minimize and maximize the application. Please help me on this to get this issue fixed.

Well the details are rather going to depend on what it's doing.
It's a very open ended question really.
But...
Your options include.
Background worker.
https://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx
DIspatcherTimer
https://msdn.microsoft.com/en-us/library/system.windows.threading.dispatchertimer(v=vs.110).aspx
Async Await
https://msdn.microsoft.com/en-us/library/hh191443.aspx
Tasks
Task.Factory.StartNew(() => { Dosomething(); });
Or just a plain thread
using System.Threading;
new Thread(() =>
Thread.CurrentThread.IsBackground = true;
// DoSomething();
}).Start();
Where DoSomething is a method.
You can also have inline code of course instead of a method.
Whilst on a different thread to the UI you can't update UI objects.
You'll get a thread affinity error message if you try.
That means you either return your results to the ui thread and process them there ( particularly convenient with async await ).
Or you update something which doesn't have thread affinity.
An observablecollection bound to an itemssource doesn't have thread affinity eg.
You do need to raise property changed at the end of your processing with that option because it notifies collectionchanged on the wrong thread and the UI won't know it changed.
Or you can dispathcher.begininvoke to get back to the UI thread.
All depends what you're doing but hopefully one of those options there will suit you.
Hope that helps.

When I try to open Firefox, it says it is running in the Task manager, but will not open until the memory has reached about 100,000k. Also, it keeps NOT responding all the time, and freezes up.

I have done everything on the support page. I am running Windows Vista, and I am running Firefox 4.01. I have even tried running in safe mode. I have updated my plugins, and then disabled plugins and extensions.

Hello Pohaku66, any luck if you [https://support.mozilla.org/kb/firefox-already-running-not-responding#w_remove-the-profile-lock-file remove the profile lock file] ?

Open Sale Order Value (FD33) not getting diminished even after closing SO?

Hi,
Upon Executing FD33 and clicking the status view for a Customer say XYZ , and then choosing EXTRAS-Open Sale Order . Say the value of open sale orders being shown is 75000. Even after closing the open sale orders (By Selecting VA05 and Putting reason for Rejection), and then also the Open Sales Order value is not getting diminished.
What could be the reason ?
Pls help.
Regrds,
Binayak

Hi Binayak,
As mentioned by you, running of Credit re-org program 'RVKRED77' is the only solution for this problem and it is known problem in SAP.
Some precautions
1. Always run the program in background by scheduling a job.
2. The idle time is around midnight when no user is working on SAP.
3. Some time the job fails as some other program may be updating same tables as this program. In such cases re-schedule the job at different time.
4. You may run the program 'RVKRED88' which will simulate without actual updation of credit values.
Hope this clarifies..
Regards,
Madhu.

Apps Tabs get don't reload after closing the firefox

I just today tried to use apps tab. I set some links as apps tab and then closed the firefox. When i stared it again the apps tab were not there anymore. However according to this release the apps tab should be retained even after closing the firefox

Go to about:config (enter it in the address bar), and find '''browser.showQuitWarning''' and set it to '''true'''. This will make Firefox ask you each time if you want to save your session to restore the next time you open it, like in 3

I switched on my PC and there was an update for realplayer. Since then firefox will not load. It is running according to Task Manager. I've downloaded a another copy of the programme using IE but whilst it loaded as a programme, does not open a window.

Hi again,
Helps if I give the correct link ! <br/>The press shift button appears to still work, but the option to start in safe mode from the programs listing of a standard install I do not think exists anymore.
Safe mode will start from a command line, (or a shortcut) and in some circumstances you may need to enter the full path name on a command or shortcut detailed instructions are at http://kb.mozillazine.org/Safe_mode
Remember (at least at this stage) do not make changes when you get the options list, just click on the continue button.
If you think that RealPlayer is causing the problem you could uninstall that for now.
Firefox recent versions are 3.6 4.0 (and 5.0 in beta). There is some debate as to whether creating new profiles or re-installing Firefox is the simplest method of troubleshooting and solving some of these problems, personally I use multiple profiles and multiple versions of Firefox, and tend to forget the required procedures are less than straightforward. For now at least try [[safe mode]] again.
* see also Instructions for [[installing a previous version of firefox]]

Firefox 4.0 will not open at all. It shows that the process is running in the task manager but will not open the window even after closing the prcess and restarting.
