Get message firefox already running but not responding when trying to launch..tells me to close firefox wondow and try again (no ffox window is open)

When trying to launch Firefox I get the following message.
"Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."
This is not the first time and I am tired of having to restart my computer. BTW I have Firefox as my default browser, but had to use IE to get to this support site!
In answer to the next question...every time I TRY to open Firefox.

Simple fix for you I think--it works for me.
1. Open your TASK MANAGER (rt click on your taskbar)
2. Go to PROCESSES
3. Scroll down until you see "firefox.exe"(or anything with the word Firefox in it)
4. Click(highlight) the "firefox.exe"
5. At the bottom right side,click "End Process"
6. Close the Task Manager and do whatever you were attempting to do.
Cheers

    There are several possible causes, see [[Firefox is already running but is not responding]].

  • Why do I get the message "Firebox already running but not responding"? I have to then restart the computer to get on the internet again.

    I go on the internet, the web site works, but then maybe when I try to go to another web site I get a message saying that Firefox is already running, but not responding and I need to close it or restart my computer. I do not know where to go to close that site so have to restart the computer!

  • "Firefox is already running but not responding" - have tried all the usual solutions.

    The message I'm getting is the standard: "Firefox is already running, but is not responding." I'm using a PC with Windows 7.
    I've tried:
    - Opening task manager and manually ending the process. This didn't work because the process is not listed in applications, processes, or services.
    - Deleting the parent/lock file. This didn't work because the file is not in any of the firefox folders. I've checked APPDATA/Local/Firefox as well as APPDATA/Roaming/Firefox, and the original install folder just to be thorough. It's not a hidden file either - I have those set to display.
    - Creating a new profile and importing settings from the old one. I can't import settings because the old profile is still running.
    - Restarting before and after each of these potential solutions, including restarting in safe mode, shutting off the computer and waiting a bit before restarting, etc.
    All I really want back are my bookmarks, which I've spent quite a while creating. Unfortunately, there is no file I can find for the default profile that has the bookmarks stored. When I created a new profile, a folder appeared with its name in the APPDATA/Roaming/Firefox folder, with all of the bookmarks, etc. There is no such folder for the default profile though - which is the one I want. I've even tried switching to Chrome and importing bookmarks, but that doesn't work because the bookmarks can't be imported while Firefox is still running.

    Does a new profile work?<br />
    * http://kb.mozillazine.org/Creating_a_new_Firefox_profile_on_Windows
    If there is no profile present then you also get that error about "Firefox is already running but not responding"
    If you uninstalled Firefox at any time in the past and removed your personal data or deleted that profile folder yourself then you no longer have a profile to start with or restore files from.

  • "Close Firefox - Error Message -. Firefox already running, but not responding -.." A real pain - Firefox worked much better before all the updates!! How do I fix this?

    This pop-up appears anytime I attempt to close Firefox and immediately open another browser, etc.
    Suspect it is add-ons related. Never had the problem with "older" version of Firefox.
    It is a real nuisance, almost makes me go to Explorer!

    Try to wait a bit longer (up to 1 minute or maybe more) as it can take some time for Firefox to close completely.

  • When I try to start Firefox, I get a message that it is already running but not responding and I can't run another Firefox at the same time. I uninstalled and reinstalled. No change. Tried various other suggestions. Help!!

    When I try to start Firefox, I get a message that it is already running, but not responding and that I should close it before trying to run another Firefox. But I cannot find a way to close Firefox program that is not running as far as I can see. I tried uninstalling and reinstalling Firefox, but that did not work. I've tried various other things, but no luck. I thought programs should stop when the computer is turned off, but that didn't work either.

    How are you opening the Profile Manager?

    Sounds that Firefox is still or already running.<br />

  • On switching on, a message says 'Firefox is already running but not responding...........' then tells me to close it and restart but how can I close it when the page isn't yet displayed?

    When I switch on my computer I get the desktop then I try to click on Mozilla Firefox but get the message, 'Firefox is already running but not responding. To open a new window you must first close the existing Firefox process or resart your system.' I looked up how to close but I need to click on 'file' then 'exit'. How can I do that when I can't see the page yet? IE is working fine.

  • Once I turn off the browser and then try to use it later, I get a message saying its already running but not responding. tells me to close it which I cant do since its already closed. Forces me to restart my computer

    <u>'''Safe Mode'''</u>
    You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox SafeMode 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 then try to find which is causing it by enabling one at a time until the problem reappears. You have to 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.

  • V6.01, Windows 7, click on icon, "firefox is already running but not responding" Task manager doesn't know about it. I can't quit it or get it to load. Brand new install. What to do?

    Brand new Lenovo computer, Windows 7 Home. New install of Firefox 6.0.1, set as default browser, don't launch when I click done. Icon appears in tray. I click the icon, and a message says "firefox is running but not responding. To open a new window, you must first close the existing process, or reboot". It's not obviously running. I can't find a way to make it quit. Task manager doesn't list it as a current application. Uninstall using the control panel uninstall function and then reinstalling gives the same message. Rebooting doesn't fix the problem and gives the same message. Firefox had been working until I tried to update my bookmarks.

    No can do. I can delete the current profile and install Firefox, which should create a new blank profile. The message still says "Firefox is already running." I can place my old profile in the proper folder, and Firefox will still be already running. I can't actually use Firefox, because even though the message says it is running, there is nothing on the screen I can access.
    After uninstalling Firefox, deleting the two items left in the Programs folder, and deleting the profile again, it still didn't work. I then got frisky and from the Roaming folder I deleted the Mozilla folder which contains the Firefox folder which contains the now empty Profiles folder. That worked, and a new set of folders with a new blank profile were created. So apparently it was the empty folders that never got deleted that were causing the issue.
    Thanks for your suggestion. It got me thinking.

  • Firefox 29.0.1 on Windows 7 (64-bit): ALWAYS get "Firefox is already running but not responding..." error and need Task Manager to close/restart Firefox.

    I run Firefox 29.0.1 on Windows 7 (64 bit) and I get the "Firefox is already running but not responding. In order to open the program you must close the existing window." error. EVERY TIME I try to start Firefox. The posted solution works to start the program, but it is not a permanent solution. I go through the Task Manager and end the old Firefox process, then I can open a new window. While working, I can open multiple tabs and multiple windows, everything seems to (usually) work the way it should. Then after I completely exit Firefox, in order to open the program again I need to fix the SAME error again. Every time. It doesn't seem to hurt anything really, but it is quite annoying.
    I used to get this same error on some of the older Firefox versions but it was only once in a while. With the new 29.0.1 it is literally EVERY TIME I TRY TO RUN FIREFOX!!!!
    So, down to the big question: is there a permanent fix for this yet? Or will there be one included in the next version update? Or am I going to have to go back to Internet Explorer? I know I am not alone in this experience; i've seen several other users posting similar questions but none of them received satisfactory answers. So what's the story here, team Firefox?

    This is not a cure but will make it easier if Firefox locks up.

  • Firefox is already running, but not responding to open a new window

    I closed the only opened Firefox process that was running. Then clicked the Fox to start Firefox again. I received a message: Firefox is already running, but not responding, to open a new window. You must close the existing Firefox process, or restart your system. This is a stupid message since there is no Firefox in process.

Please help :(

    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
    Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
    To Reset Firefox do the following:
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox" button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.
    Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

    == This happened ==
    A few times a week

    Firefox is shutting down windows I want to remain open. Example: I am done viewing one window. I click the X to shut the window and it shuts two windows. Every single time, attempt to close one windows, two windows close. Lately, I have been opening several windows with nothing but google search, just so it will shut that window and not something else I want to remain open. I could understand this if I was using tabs, but I am not. This has been going on for over two weeks. I don't like going back to history to open a window, I did not want closed in the first place. Isn't that what 'Windows' is all about? Any ideas?

    Latest revision of firefox.
    After using firefox for a while if I exit, parent.lock is locked and i have to reboot to reload firefox.
    I have killed all firefox applications from task manager (usually there are none). and I have tried 3 different "file unlock" programs including unlocker to no avail.
    I also recently installed a program that shows -all- open files, and parent.lock is not listed, and thus not closable/unlockable from there.
