How do I stop this error "Firefox is already running, but is not responding"

Hello,
I got this issue where I’m logged into more then on computer at a time. If I have Firefox running on one computer I’m prevented from running Firefox on anther computer. This because my user account has its home directory mounted across all the computers. It appears that the lock file is preventing from running Firefox on the 2nd computer. What I have been doing is deleting the lock file in my home directory. Then I’m able to start Firefox on the 2nd computer. Is there a better way of doing this? Is there away to disable the use of the lock file?
Now I could just exit out of Firefox on the 1st computer but what if I’m running a web app on the 1st computer. What if you are using a shared admin account to such as root or using a RBAC profile. If user1 is using Firefox after become root or assuming a role, then no other user can use Firefox as root or using that role. That makes it very hard to use Firefox then.
Anyway this is mostly a UNIX/Linux question.

Hello,
I thought I should update this post with the answer.
In order to get around the lock file. You can delete it or use profiles.
If your running Firefox from a UNIX, BSD or Linux based OS. To get to the profile popup window use the -p option.
firefox -p
Which will look like the image below.

To get the popup all the time uncheck the "Don't ask at startup"
If you don't have a GUI running then you can do this.
firefox -CreateProfile ''profilename''
firefox -p ''profilename''
I hope this helps someone out.

    Update firefox, it asked me to update flash, I tried to update flash but it said I had to close firefox. A box came up and said the Flash install would continue when I closed firefox. I closed all firefox windows and no update of flash occurred. I tried relaunching firefox but got the "Doesn't start when starting as administrator. Error 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." message. I rebooted the system, no improvement. I tried to run firefox as administrator and got the same message. Either I find a fix or I won't be able to use firefox and will have to go back to ie.

  • Why does firefox stop loading then when i close it and try to open it up again I keep getting this 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

    Firefox will just stop loading/ connecting to the internet. The gray circle will just continually move but it never turns green to load the pages. I know it's not my internet because my internet explorer works just fine while this is happening to firefox. So I close firefox and then try to re open it but I get the 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. So I wait a little bit then try and re open it and still get the same message. I then go into my windows task manager and try and end the firefox proccess but it won't end. So I restart my computer and firefox eventually starts acting up again.

    Firefox will be hanging for some reason. The quick solutions to kill the process and try again. The next step is to try to see if it will start and exit normally a couple of times, if so the problem is solved. If not the reason needs further investigation.
    See [[firefox hangs]]
    An immediate likely culprit after repeated problems are the duplicate session restore files, as discussed in the above KB article.

    I am using Windows 7 Home Premium 64 bit. I do not recall the problem occurring when Windows 7 was first released. This has been happening for several months now with all versions of Firefox. 3, 4, and 5. I have searched online for a solution to this problem. I have tried every fix listed here and online that I could find. The problem remains. Does anyone have a fix for this?

    The following may not completely eliminate having to terminate Firefox through the Windows Control Panel but it will come very close.
    '''Plug-in and tasks started by Firefox may continue after attempting
    to close Firefox''' The "X" in the upper right-hand corner closes the
    Window (same as Ctrl+Shift+W) but even if it is the last Firefox window,
    it does not necessarily close Firefox .
    The only '''proper way to exit Firefox''' is to use '''Exit''' through the
    File menu, not the "X" in the upper right corner of last Firefox window.
    In the Beta that would be Alt+F then X

    Use the '''Windows Task Manger''' to remove all running firefox.exe in the "'''Processes'''" tab of the Windows Task Manager, then restart Firefox.
    If Firefox will still not start, remove the parent.lock file from the profile which is created each time Firefox is started to prevent other Firefox tasks from running, see<br>

    Hi Pelle,
    Why did you delete your profile? Also how? Did you use the profile manager or did you delete from the windows file structure?
    It sounds like something during the profile delete has stopped Firefox from starting up. Please see the this article and follow the steps:

  • This 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." can you help and what is the Firefox process it refers to?

    This happens straight after I have closed Firefox browser and then straight away, I want to open it again. Otherwise it will give this message and I will have to wait until it supposedly closes whatever is supposed to be running so that it can open -annoying!

    The process is "firefox.exe" you will only see it in the "Processes" tab of the Windows Task Manager, since you don't see it on the Windows Task Bar. You will have to terminate it from
    there, since it was not actually closed.

  • Firefox is already running but is not responding... I get this error ten times a day or more!

    I love Firefox and don't want to use a different browser, but the error "Firefox is already running but is not responding" is driving me crazy. The reason I get this error is because I frequently use http shortcuts from my desktop or click links from within a thunderbird email. I hope someone has a solution other than "just use bookmarks" or "just end the task". This is a legitimate (and major) bug and should be fixed! Thank you.

  • Firefox is OPEN and working fine, but when I click a link in Thunderbird I get '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.'

    If I click a link on my desktop or in any other program (while Firefox is open and running), I get this 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." There's about a billion links for this if you Google it, but they all say that Firefox wasn't shut down properly. (OK, maybe not ALL of them, but if the needle is in that haystack, I haven't yet found it.) That's not the issue in my case since I haven't shut FF down at all.

  • "Firefox is already running but is not responding" error message and recent firefox update

    "Firefox is already running but is not responding" error message is continuously popping up after the recent firefox update. I have nearly exhausted every possible solution to the problem as seen from the support page for this error message. I know someone who has the same issue on their computer and it also started right after the recent big update. Does the update have anything to do with this reoccurring issue? Is anyone else having this problem? Any other ideas on how to fix it? It would be great to get some help.

    From what I have been reading from other posts on this forum, the
    issue may be caused by the clear history settings.
    Press the '''<Alt>''' or '''<F10>''' key to bring up the tool bar.
    Followed by;
    Windows; '''Tools > Options'''
    Linux; '''Edit > Preferences'''
    Mac; ''application name'' '''> Preferences'''
    Then '''Privacy'''.
    The button next to '''History''', select '''Use Custom Settings'''.
    At the bottom of the page, turn on '''Clear History When Firefox Closes.'''
    At the far right, press the '''Settings''' button. Turn on ONLY '''Cache''' and
    '''Form And Search History''' leaving the others off.
    This is not a cure but will make it easier if Firefox locks up.

  • Error message "Firefox is already running but is not responding" - I have read and action the KB - no fix

    So before we start - I have read the KB (https://support.mozilla.org/en-US/kb/firefox-already-running-not-responding) and actioned the advice on how end the processes, delete the parental lock, etc. This gives a temporary but one time only fix and does not resolve the overall issue.
    I have also uninstalled and reinstalled the application.
    So why do I get the Error message "Firefox is already running but is not responding"?

    *http://kb.mozillazine.org/Profile_in_use
    Note that in Firefox 13+ (expected to be released June 5) the parent.lock file is no longer deleted after closing Firefox to make it possible to check for startup crashes, so the presence of that file will in the future no longer indicate a problem.
    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
    There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
    If the 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.
