Firefox does not close in the normal fashion. I have to go to Task Manager and end the process

I am operating on a Windows XP OS. I have been a FireFox user for several years. I am using version 3.6.13 Several months ago I noticed that if I closed FireFox I could not open it again. I got a message box stating that FireFox was still running. And, I fact, Task Manager did show that it was still active. I had to end the process there, before I could open FireFox again. It will remain active in the background and the CPU will be maxed out, thus creating problems for other programs. How can I remedy this problem? btw, I have trouble opening IE now.

Whenever I shut down iTunes on my computer, it keeps reopening and I have to go into Task Manager and end the process in order for it to stop doing this. I am running it on a Windows 7 Home Premium 64 bit machine.

Whenever I shutdown iTunes on my computer, it keeps re-opening and I have to go to Task Manager and end the process in order for it to shutdown.

Do you have Logitech gaming software installed on the PC? If so, perhaps try the suggestion from the following post:

Firefox 4 is not appearing in Task bar or some times it is Disappearing from task bar when i am minimising the window. so, i had to go to Task manager and find the icon.Its becoming big messy if tabs are not found , to switch programmes.

firefox icon is missing from "Task bar"when i am minimising the window

I am unwilling to attempt navigation away from these sites. The pop-ups that occur on the attempt to leave a site or to close the browser are exit traps offering incentive to stay.
Once upon a time, when the internet was less dangerous, I would be willing to close the exit pop-ups. Now, after twice being infected with malware trying to close the pop-ups, I now force close whichever browser I am using.
Recently, I clicked on the red X to close one pop-up, and it installed a trojan that I had to pay to be removed. When I clicked on 'Leave' in another exit pop, it didn't exit and it turned out I was giving permission to run a script file. Now that criminals have learned these exit pop-ups can be used to force a click action, the sites using them have become dangerous.
If I force the browser to close using Task manager, Please tell me how to stop FireFox from sending me directly back to the same site because it mistakenly believes it crashed when it did not. I forced it to close because I was on a site that had taken control of my browser and was not allowing me to leave the site.
No other browser sends me back to the potentially dangerous sites. I prefer Firefox, but the new version must have a setting that allows me to get safely away from a problem site?

Firefox does not start when I click, but consume a lot of resourcein task manager

Hello,
Since a few days, when I click Firefox, it does not start anymore (browser Windows does not appear anymore).
Also, I noticed that after I click, my computer makes a lot of noise et becomes slow & gets almost blocked: I can see that in the task manager/processes, firefox is there and consume a lot of memory ressources.
Can you help ?
Thanks

Hello,
Thanks for you reply. What you propose me is to create a new profile and transfer the files from the old profiles to the new.
I am not interested by this option as I want to keep my current profile as I am using programs working on this profile and also have Firefox working on this profile.
But I have a new information which might help. I did not see it during my last tentative but after a few minutes after Mozilla launch, there was like a bug report which were generated.
I copy paste below. Hope that it can help :

When I close out Firefox, it arears to close. It returnes me to Desktop; however, it does not close. It keeps running, and because of this, I cannot open it up again without opening the Task Manager and ending the process first. What is causing this?

Firefox works fine except for the hicup of not shutting down. If you don't know what is happening, you won't know why it won't open up.

See "Hang at exit":
* http://kb.mozillazine.org/Firefox_hangs
* [[Firefox hangs]]

When I close firefox (in windows 7), it doesn't fully close, I have to go to the task manager and end process before I can open it again.

Every time I try to open firefox, a window pops up saying that another instance of firefox is already running (still open from the last time firefox was open) and that another instance can't be opened. To solve this, I have to go into task manager and end the firefox (32) process. I think this started happening after getting the newest version of firefox a couple weeks ago. My computer is a month-old thinkpad with windows 7 64 bit.

Firefox won't stop running unless I go into task manager and end process

when I shut down firefox and then later try to start it again a box comes up that says it is already running but it won't come on. So I have to go into my task manager and end the process before I can start it again. How do I solve this problem?

That is "hanging at exit". You can ignore the first part, since you already know how to do that.

* You may need to try Firefox Safe Mode
** You may need to use '''Safe Mode''' to locate the problem:
***See:
****https://support.mozilla.com/en-US/kb/Safe%20Mode
****http://kb.mozillazine.org/Safe_Mode
***Firefox 4 users, hold the Shift key while clicking the Firefox 4 desktop icon to enter Safe Mode.
***Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox.
****In Firefox 4, Safe Mode also disables Plugins and Hardware Acceleration.
****If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode (In Firefox 4, Tools > Add-ons > Appearance). See: http://support.mozilla.com/en-US/kb/Using%20themes%20with%20Firefox#w_managing-themes-and-personas
****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.
*** 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 '''one at a time''' until the problem reappears.
***#You can also enable a few at a time (3-5), keeping track of what you just re-enabled to see if the problem re-occurs; this will help narrow down the possibilities if you have a large number of add-ons.
***#'''You MUST 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.

When closing my Firefox window, all processes are not closing requiring me to open task manager and kill the process before using Firefox again. Received recent upgrade and hasn't worked right since then.

I open Firefox, use it, then close the window. Try to reopen Firefox and it fails with a message that a previous process is still running. Requires me to open Task Manager and kill the old process.

Try to wait a bit longer before reopening Firefox to give Firefox more time to close completely. 
Try to use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.

There may be a problem with one of the files that stores details of installed extensions. Try deleting these files as shown in the "Corrupt extension files" section of this link - https://support.mozilla.com/kb/Unable+to+install+add-ons
Though that article is not specifically about your problem, the method shown in the corrupt extension files section may help. When you restart Firefox after deleting those files, the list of installed extensions is rebuilt and this will hopefully fix your problem.
