I unistalled firefox because it said "Firefox is already running but is not respond," Now I try to reinstall it but it won't load.
I tryed to open Firefox but instead, it came out an error saying something like "Firefox is already running but is not responding." So, I desided to uninstall it. Now when I go to Install it again on getfirefox.com, the system does not run automatically. Nothing happens! Please help.
Bring up the Windows Task Manager, then on the "Processes" tab NOT the "Application" select "firefox.exe" and use the "Del" key or the "End Process" button,
can also be done from the context menu there.
To bring up the WTM by right clicking on empty space on your Windows task bar, then clicking on "Start Task Manager".
Firefox must be taken down for the install to continue once the installation starts. The proper way is to use File > Exit, but if Firefox is still running, you will need to use the task manager to terminate Firefox.
When reinstalling Firefox from a download, Firefox must be down once the installation starts. When the installation finishes, don't let the install start firefox for you. Instead end the install and start Firefox in your normal manner, thus preventing creating a new profile which does not have your bookmarks cookies, etc (but your old profile would still be around and would).

when I click the firefox link a window pops up saying a the program is already running and I must close that program in order to run a current one. I went through task manager and then completly uninstalled firefox and reinstalled the newest version. This did not help.

When I logged on, a little screen told me to update "My Points", then restart Firefox. It never reloaded. The MyPoints people never called back. So, I dumped the whole thing in the trash and deleted it. When I tried to reinstall Firefox, it said, my system wouldn't take it. I have the same system that I had yesterday, when everything was hunkey-dory! Mac OS X (10.4.11)
Firefox 4 and later require at least OS X 10.5 and an Intel Mac.

I downloaded a new version of firefox. It said it had problems with my norton toolbar and now it doesn't feature it in the window. I'm not that comp savvy. How do I either get the Norton toolbar up or go back to the old firefox? Thank you.

This is the message I get whenever I click on the Foxfire icon on my computer. Even when it has been down for hours:"Foxfire is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."

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.
-> press '''CTRL''' + '''SHIFT''' + '''ESC''' to Open Task Manager -> Processes tab -> right-click '''firefox.exe''' and click '''End Process Tree''' -> close Task Manager

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. To open a new window, you must first close the existing Firefox process, or restart your system.
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 is closed, I am doing something else, need to reopen it but I can't because of that message.
I use Firefox since 2004See this article - [[Firefox is already running but is not responding]]
In your case Firefox may not be shutting down properly. -
Sometimes when I close Firefox and try to open it in few moments it shows me 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." However, I haven't opened any additional Firefox related programs, and previous Firefox is closed. First I though it is because of my computer, but then I discovered that other people have the same problem as well

First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:

Hopefully this will help. -
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]].

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.
Hello,

When I try to launch Firefox I am told it is already running
I get this error 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. When I go to task manager/applications tab, nothing shows up, but when I go to task manager/processes tab, sure enough, it does look like it is running already. I went to msconfig and it does not appear that firefox is one of my startup jobs.
During shutdown, laptop has to do a forced shutdown sometimes because it says a job is still running (though I can not see one doing so). Again I go to task manager processes and there is Firefox, running invisibly again. What is up with this and how to I correct it?He's not registered with iMessage.
He either does not have an Apple device or has not signed up for the service.
iMessage only works with other apple devices.
If he does not have one, you will need to download an app such as text+ to send regular text. -
I have tried rebooting the PC and can open Firefox once but if a close and try to reopen, same message pops up. Have also unistalled and reinstalled, to no avail.
For possible causes see [[Firefox is already running but is not responding]].

I've even uninstalled Firefox and then reinstalled in the hopes that the problem would be solved but it this message is still popping up. What can I do to solve this problem?
