Firefox 4.0 won't close, have to close via task manager (Vista).

I am unable to close Firefox 4.0 from "X' in upper right corner, File/Exit, or Right-Clicking on taskbar and selecting Close. Have to open task manager to stop the process. Running a Vista machine, never had this issue with any other program (or any Firefox version).

Create a new profile as a test to check if your current profile is causing the problem.

*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

  • Often, Firefox app will close, but the underlying Windows process will not and cannot be stopped via Task Manager. When this happens, Firefox can no longer be used...the system must be rebooted.

    Hello,
    Often, the Firefox app will close, but the underlying Windows process will not and cannot be stopped via Task Manager. When this happens, Firefox can no longer be used...the system must be rebooted. This happens especially when many apps are running but even though there are plenty of memory resources available.
    I have tried to find if something is using Firefox in the background, but have no way to know what that would be.
    Their are no apparent viruses detected.
    Firefox is version v5.0 and occurred in earlier release.
    System is Windows 7 (64bit).

    well, it's not the same hardware and it's a bit different.
    I managed to pass that stage somehow but I still have a problem
    I don't use the built-in creator tool that comes with Spyrus as it doesn't know how to append a pre-staged media that was created by SCCM that should apply the Windows file system to a second partition and the WinPE to the first partition.
    I managed to do everything. my only problem is that the WTGCreator that comes with SCCM 2012 R2 creates the 350MB partition with FAT32 file system.
    when I boot from the device I get the WinPE, I can choose a task sequence and then it fails when trying to apply the wim file. the error tells me that the 350MB partition is FAT32 which is not supported (even though it chooses the second partition, which
    is all the rest of the disk space)
    what I did was adding another task that converts the 32 Fat partition to an NTFS partition and then the process continues and finishes successfully! but that's a workaround.
    I'm trying to make this process as smooth as possible without having additional steps

  • Whenever I shut down iTunes on my computer, it keeps reopening and I have to go into Task Manager and end the process in order for it to stop doing this. I am running it on a Windows 7 Home Premium 64 bit machine.

    Whenever I shutdown iTunes on my computer, it keeps re-opening and I have to go to Task Manager and end the process in order for it to shutdown.

    There may be a problem with one of the files that stores details of installed extensions. Try deleting these files as shown in the "Corrupt extension files" section of this link - https://support.mozilla.com/kb/Unable+to+install+add-ons
    Though that article is not specifically about your problem, the method shown in the corrupt extension files section may help. When you restart Firefox after deleting those files, the list of installed extensions is rebuilt and this will hopefully fix your problem.

  • At various websites, I am constantly getting a "Stop Script..." error message. From that point I have to use the task manager to close firefox. Why????!!!!

    I realize that websites now have a whole lot of extraneous stuff running, but this is getting ridiculous. This is a powerful pc with a fresh install of windows 7. These damn "stop script" messages are ruining my browsing experience. It gives me two choices, continue or stop, but neither works. I can't get rid of the error message and I can't close firefox. I can't do anything except call up the task manager and end the program. The last time, even after that, the damn website was still playing in the background after firefox had closed, and I had to force a restart on the computer.

  • Firefox does not close in the normal fashion. I have to go to Task Manager and end the process

    I am operating on a Windows XP OS. I have been a FireFox user for several years. I am using version 3.6.13 Several months ago I noticed that if I closed FireFox I could not open it again. I got a message box stating that FireFox was still running. And, I fact, Task Manager did show that it was still active. I had to end the process there, before I could open FireFox again. It will remain active in the background and the CPU will be maxed out, thus creating problems for other programs. How can I remedy this problem? btw, I have trouble opening IE now.

  • Firefox grows to 200,000K and hangs; have to close with task manager--please help!

    usually happens when I'm on AOL...After I close Firefox with windows' Task manager, I can restart Firefox. I'm using Microsoft Windows XP. I get the usual, message on Firefox restart about unexpected closing of previous session... I'm running the latest version of Firefox and i use McAfee Security and Microsoft Security essentials. It is happening now even though I'm NOT running AOL

    Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

  • Firefox won't open. I followed instructions in help. I closed Firefox via Task Manager, processeRestarted my comp. It still won't work. (as a test I ran Explorer to see if that would work. It does.) What can I do to get Firefox working properly?

    These are the help suggestions from Firefox Help that I followed:
    Firefox will not start and no error message is shown
    Another program may be preventing Firefox from starting. Restart your computer to end all running programs then try starting Firefox again. If Firefox still does not start or if the problem returns, the other suggestions listed below can help you fix the problem.
    An extension prevented Firefox from closing properly
    Sometimes your previous Firefox session did not close properly and this prevents you from restarting Firefox. Norton IPS, Norton Toolbar, and Skype 4.0 are all known to prevent Firefox from closing properly. Firefox is still running, but no windows are open.
    note: TO MY KNOWLEDGE I DON'T HAVE NORTON
    1. Right-click on an empty spot in the Windows task bar and select Task Manager (or press Ctrl+Shift+Esc).
    Note: On newer versions of Windows (XP, Vista, 7) the combination Ctrl+Alt+Del opens Task Manager as well.
    notron360sucks-taksmanager.png
    2. When the Windows Task Manager opens, select the Processes tab.
    TaskManagerProcesses.png
    3. Select the entry for firefox.exe (press F on the keyboard to find it) and click End Process.
    4. Click Yes in the "Task Manager Warning" dialog that appears.
    TaskMgrWarning.PNG
    5. Repeat the above steps to end any additional firefox.exe processes, if more than one entry is found, then exit the Windows Task Manager.
    6. Start Firefox normally. NOTE: THIS IS WHAT DOESN'T WORK AFTER CLOSING THE PROCESS IN TASK MANAGER AND RESTARTING THE COMPUTER...THEREFORE I COULDN'T DO THE REST OF THE INSTRUCTIONS
    7. At the top of the Firefox window, click on the Tools menu, and select Add-ons.
    8. Select the Extensions panel.
    9. (If it is listed) Select Norton IPS and click Disable.
    10. (If it is listed) Select Norton Toolbar and click Disable.
    11. (If it is listed) Select Skype 4.0 and click Disable.
    12. Click on Restart Firefox.
    ADDITIONAL NOTE: BEFORE THIS PROBLEM STARTED TODAY I WAS ON THE WEB LOOKING UP A PHONE NUMBER = THERE WAS SOME WEIRD JAVA ERROR MESSAGE SO i DIDN'T DOWNLOAD THE PAGE AND EXITED. SOMETIME LATER IS WHEN FIREFOX NO LONGER WORKED.

    Hi mcclausky, you may need to manually remove a policy setting from the registry. You also should scan for malware that might have created this problem.
    This article lists scanning and cleaning tools other Firefox users have found helpful: [[Troubleshoot Firefox issues caused by malware]].
    To check your Windows registry for policy settings that might affect Firefox or other programs, I suggest consulting a Windows forum or Microsoft's forums. For example:

  • Firefox won't start, but is running in Task Manager

    I was running 3.x for a long time with no troubles.
    Last week it crashed, and since then I have been unable to start Firefox although it is showing as running in the Task Manager when I attempt to start it.
    So it opens no window, but appears to be running.
    Same for Safe Mode.
    Same for Profile Manager.
    Can't use switch to from task manager.
    I uninstalled 3.x and deleted all mention of Firefox or Mozilla from the registry.
    I installed 4, and still have the exact same problems.
    Running XP with a load of business apps, but nothing installed recently.

    There may be a corrupted file on Firefox.<br>
    Please attempt to perform a clean reinstall. <sup>[https://support.mozilla.org/en-US/kb/forum-response-clean-reinstall (More Details)]</sup> This is different than a regular uninstall.
    If a clean reinstall does not fix the issue, please try starting your operating system in safe mode.<br>
    To do so, please do the following:
    #Ensure that your computer is shut down completely
    #Press the power button
    #Tap the <code>F8</code> key repeatedly before the Windows logo and startup screen is displayed
    #Select Safe Mode With Networking for the advanced startup options list
    Please report back with the results of both solutions.

  • My iTunes 10.6.1.7 automatically restarts every time I close the program.  I have to open the Task Manager to close it and keep it closed.  Any suggestions to fix?

    I have closed the program repeatedly, but every time I do it reopens within a few seconds.  The only way I have found to make the program STAY closed (not using memory and CPU time) is to force it to close in the Task Manager.

    Do you have Logitech gaming software installed on the PC? If so, perhaps try the suggestion from the following post:
    Re: Everytime I close Itunes it loads back up

  • Firefoxsometimes takes awhile to close. Periodically have to end process via task manager. 'Any ideas?

    I close Firefox. It immediately closes and disappears from the task bar. At times, if I try to open it within 5 or 10 seconds after, it will display a message that '....Firefox is already running......' and will not launch Firefox until waiting for a few more seconds. In the last couple days, it has appeared to be closed when I close it (same scenario as above). But it is saying it is still open for an extended period of time - 30+ seconds. So I go into task manager and end the process. Then it will launch.

    -> Tap '''ALT''' key or press '''F10''' to show the Menu Bar
    -> go to Help Menu -> select '''Restart with Add-ons Disabled'''
    Firefox will close then it will open up with just basic Firefox. Now do this:
    -> Update ALL your Firefox Plug-ins https://www.mozilla.com/en-US/plugincheck/
    -> go to View Menu -> Toolbars -> '''Menu Bar''' and '''Navigation ToolBar''' -> unselect All Unwanted/Incompatible Toolbars
    -> go to Tools Menu -> Clear Recent History -> '''Time range to clear: select "EVERYTHING"''' -> click Details (small arrow) button -> place Checkmarks on '''Cookies, Cache''' -> click '''Clear Now'''
    -> go to Tools Menu -> Options -> Content -> place Checkmarks on:
    1) Block Pop-up windows 2) Load images automatically 3) Enable JavaScript
    -> go to Tools Menu -> Options -> Security -> place Checkmarks on:
    1) Warn me when sites try to install add-ons 2) Block reported attack sites 3) Block reported web forgeries 4) Remember Passwords for sites
    -> go to Tools Menu -> Options -> Advanced -> Network -> Offline Storage (Cache): click '''Clear Now''' button
    -> Click OK on Options window
    -> click the Favicon on SearchBar -> click '''Manage Search Engines''' -> select all Unwanted Search Engines and click '''Remove''' -> click OK
    -> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE All Unwanted/Suspicious/Incompatible Extensions (Add-ons) -> Restart Firefox
    -> go to Tools Menu -> Add-ons -> Appearance section -> REMOVE All Unwanted/Suspicious/Incompatible Themes (Persona) -> Restart Firefox
    You can enable your Known & Trustworthy Add-ons and Themes later. Check and tell if its working.

  • (Vista) Firefox will not start; claims operational but is not in task manager

    Firefox likes to crash on my 64 bit system, and if I close I usually have to go manually close the .exe file through task manager. I uninstalled completely hoping to fix my Javascript error (popups won't work and I have it set so they can >.

    I don't know about the error message you got but that is not the way to start a different version of Firefox -- include the pathname. And if you are trying to share a profile that is bad also as you could damage a profile, though Mozilla does try to avoid damaging, you should not mix the production version profile with one of a beta unless you are looking to create/solve additional problems for those that inadvertently do that. What does the UX stand for after 10.a1
