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.

Every time I try to load firefox, WindowsXP says firefox is already running but not responding and before it can load another I have to shut down the one running and reboot my computer.

My problems started when I downloaded Ilivid downloader, after I loaded the program and watched the short video the program started messing up my computer. It spread itself all over my hard drive, changed my homepage, my search engine, locked me out of being able to change certain settings, made some of its files undeleteable and since then my firefox will not load. I removed my version of firefox and reinstalled it several times. I still got the same response. I went into the registry and deleted all references to Mozilla and Firefox and reinstalled it again, same response. I spent days trying to delete all references to ilivid downloader and every file I could find that made any reference to ilivid. I hope you can help me with my problem. I like using firefox and would like to start using it again. Thanks

* [[Firefox is already running but is not responding]]
Try closing any running instances of ''firefox.exe'' (and plugincontainer.exe) using something such as Task Manager. That should allow you to then restart Firefox.
As for iLivid. Possibly it also has associated apps or extensions with names not including the word iLivid. Looking at their own FAQs there are instructions to remove iLivid using the Windows Control panel, and mention of other bundled software that you may wish to remove. It seems it is more of a nuisacne rahter than out and out malware.
* see http://www.ilivid.com/faq.htm (page scrolls for more info) but includes:
How do I uninstall the software?
The software can be removed in a simple was like any other software:
Go to the Windows Start menu and then to Control Panel > Add/Remove ("Programs & Features" in Vista & Windows 7) and click "Remove" next to the software name (e.g iLivid Download manager / Windows iLivid Toolbar ).
During the installation bundle software are offered, each can easily be removed following those instructions: Uninstall Yontoo Addon , Uninstall Search Toolbar (powered by Bing) or Uninstall Babylon.

I get the message "Firefox is already running but not responding" and I have tried all of your solutions and nothing has worked so what do I need to do?

My daughter downloaded Babylon (incredibar) malware and we tried to reset Firefox. It got hung up and I closed the window. When I tried to restart Firefox, I got the messsage "Firefox is already running...". I uninstalled and reinstalled Firefox as well as restarting the computer a number of times. I followed the Mozilla help info and deleted the profile locked. parent(?). I use Windows 7 Ultimate.

hello sdandccids, unfortunately this babylon software is hooking-in deeply into the system. especially the component browsemngr.exe (+dll) is known to crash firefox and possibly might also cause the issue you're experiencing.
please go into the windows control panel > programs section and sort the software according to installation date & then remove all entries that got installed at the same date as the babylon toolbar and you're not familiar with ([https://support.mozilla.org/questions/935739#answer-367152 according to babylon] this might be "Browser Manager" + "Bprotector" + "Object Installer" + "Babylon Toolbar on IE").
in case this doesn't work or there are no such entries showing up, please hit ctrl+shift+esc and search if there is a file named browsemngr.exe showing up as running in the list of processes - if so here are instructions for a manual removal (unfortunately quite technical): www.explosiveknowledge.net/main/2012/08/19/browsemngr/
otherwise you can also try a "clean uninstall". uninstall firefox from the windows control panel & chose to remove all personal data. afterwards manually check if the firefox program folder got deleted (it's usually in ''C:\Program Files\Mozilla Firefox'') and else remove it manually. then download & install a fresh copy at getfirefox.com
i'd furthermore recommend doing a full scan of your system with the security software already in place and/or a different tool like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] since this firefox start-error can also be a sign of other [[Troubleshoot Firefox issues caused by malware|malware]] active on the pc.

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.

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.

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?

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.

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.

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.

Not sure how often

Hello Lara.
Hopefully this support article is what you need:
http://support.mozilla.com/en-US/kb/Firefox+hangs#Hang_at_exit

For the last two days, firefox has been freezing or Not Responding and giving error message

every 30 seconds or so firefox tells me it is not responding. and once it comes back it gives me the following error message.
A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: http://cdn4.specificclick.net/img/?ag=1&pb=9788&pg=293059886053054629&us=IuOJnv_awGu5HD&nwk=1&rnd=53585:3534
I did install a java update, don't know if this is related.

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] (don't forget to select ''Disable all add-ons'' when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and themes and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem does not disappear when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.

I have the latest version but I am continually told that Firefox is running but not responding and that I need to close Firefox or restart my computer to clear the problem. Why is this happening?

Firefox shows in tasks but not on desktop. Have uninstalled and reinstalled but no change

I was using Firefox ans suddenly it will not show on desktop. It shows in Task Manager but NOT on desktop. Have uninstalled and reinstalled 3 times to no avail. Can you help? I hate all the other browsers!

Are you sure there is no problem at the source? Have you tried contacting the publisher to see if they are sending the right files? And the format of the files?

When not on Firefox and go to do it, why am I constantly getting: "Firefox is already running but not responding. To open a new window you must close the existing Firefox process, or restart your computer." Moreover, HOW CAN I STOP IT FROM HAPPENNING???

Every time I have to re-start my computer I need to stop my work. It would sure be nice if you can tell me how to keep this from occurring.
Thank you.

Sounds like Firefox isn't closing down completely when you exit it. <br />

When I use a GSI external antenna for WiFi I first get a message that "Firefox is already running but not responding etc", and then Firefox crashes. Can anyone help please?

Because of weak WiFi signal I need to use an external antenna (GSI USB wireless WIFI long range network adapter). My computer can see the signal clearly and shows that I am connected to the right network. But when I try to launch Firefox I get a message that "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." When I click "OK" Firefox tries to load websites but gives up and reports "Problem Loading". It looks like Firefox is having trouble "seeing" the signal from the external antenna. What do I need to do please?

Try Ubuntu support, I don't think your problem is with Firefox - it will use the connection that the Operating System "makes". I'm a real noob with Ubuntu myself, and don't think I can help you figure out the problem.
