Frequently when I open Firefox it says Firefox is already running but is not responding. I have to go to the task manager, find Firefox and close the process before I can get firefox to load.

Those are all the details I have

  • 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"?

    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.

  • 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.

    somehow i couldn't get rid of one website called www.searchqu.com/405 set as my homepage... I tried all solutions given to change the homepage but whenever i restarted firefox that homepage used to come automatically.. So, I deleted the profile (even from recycle bin!!) and deleted the firefox and downloaded it again hoping to get my problems fixed (which didn't happen!) because i'm getting dialog box saying- Firefox is already running, but is not responding.

    You don't say which operating system you have installed?
    Assuming it's Windows, right click a blank part of the Windows Taskbar and go to Task Manager. Then click the ''Processes ''tab, find '''firefox.exe''' and then right click it and choose '''End Process'''.

    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.

  • Firefox keeps hanging up and freezing. I get this message. "Firefox is already running, but is not responding. To open a new window, you must first close the existing--what a mess.

    No matter how many times I open and close, firefox hangs up after surfing a few pages. When I look at task master, firefox is using up hundreds of thousands of kb, causing the processor to stall at 100%. I do not have this problem when surfing with IE. I have the latest version of firefox. I never had this problem with version 5. It keeps getting worse with each "update".

    See [[Firefox is already running but is not responding]]
    Obviously firefox should not hang after surfing a few pages. I have Firefox installed on an XP including firefox 6.0.2 and do not have problems.

    Have a read of the above linked articles. The first thing to do is to try to get firefox to behave more normally
    #Use [[safe mode]]
    #* but do not make changes when you have the window with a list of options just click continue
    # if using safe mode does not solve the problem also
    #* make sure you use the default theme

    <u>'''Safe Mode'''</u>
    You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox Safe Mode 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 <u>'''before'''</u> 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 Plug-ins and then try to find which is causing it by enabling <u>'''one at a time'''</u> until the problem reappears. <u>'''You MUST close and restart Firefox after EACH change'''</u> via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

  • 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.

    For possible causes of this error, and how to troubleshoot it see [[Firefox is already running but is not responding]].
