Firefox keeps running after closing using 90% plus of CPU, WHY?

Using task manager FIREFOX continues to use a high percentage of CPU after closing it.
Running XP SP3
Exploerer continues to run also but a more reasonable CPU usage

Firefox stays running after closing using the "X" to close program. XP OS

Closed Firefox V6.X on XP OS using the "red X", come in the next day, click icon to open, error is that Firefox is already running. Checking Task Manager shows that it is running, have to use Task Manager to close program in order to start firefox. This happened in a previous version of FireFox.

Adobe 11.0.3 keeps running after closing the program and uses all cpu

After closing Adobe reader it remains in the background on task manager and uses about 25% of CPU for each instance, each time a pdf is closed it adds another instance in the background, when there are four my cpu is maxed out. I have to use my computer with task manager always running so I can end task each time I close a PDF. I tried the solution stopping welcome screen with registry fix and other fixes for prior versions, none help. Running Windows 8.

In order to deploy via GPO, you need to create AIP (Administrative Installation Point) for Reader 11.0 and then patch that AIP with 11.0.04 to create AIP of 11.0.04
Method:
1. Extract Reader 11.0.4 exe via the following command line,
AdbeRdr11004_en_US.exe -sfx_o"<extraction_path>" -sfx_ne
e.g. if you want to extract to c:\temp_folder
you should run the following command,
AdbeRdr11004_en_US.exe -sfx_o"c:\temp_folder" -sfx_ne
You should see the following six files in c:\temp_folder,
ABCPY.INI
AcroRead.msi
AdbeRdrUpd11004.msp
Data1.cab
setup.exe
Setup.ini
2. Now navigate to "C:\temp_folder" folder to create AIP for 11.0 in "C:\Rdr11AIP" and follow the wizard
msiexec /a AcroRead.msi TARGETDIR="C:\Rdr11AIP"
3. Now navigate to "C:\Rdr11AIP" to create AIP for 11.0.4 in C:\Rdr11AIP" and follow the wizard
msiexec /a AcroRead.msi TARGETDIR="C:\Rdr11AIP" PATCH=<"Path to 11.0.04 patch location">
for this example, "Path to 11.0.04 patch location" is going to be "c:\temp_folder\AdbeRdrUpd11004.msp"
So the command would be,
msiexec /a AcroRead.msi TARGETDIR="C:\Rdr11AIP" PATCH="c:\temp_folder\AdbeRdrUpd11004.msp"
4. You will see following files in your "C:\Rdr11AIP" folder,
AcroRead.msi
Common
CommonAppData
program files
Win
Windows
5. Now copy the contents of this folder to your network location and link the AcroRead.msi file in the Group Policy Editor, you are now ready the deploy 11.0.04
Hope, it helps.

Adobe processes keep running after closing program!

Hello,
I have this issue with Adobe Premiere Pro, After Effects, Media Encoder and Audition but not with Photoshop, Dreamweaver etc.
Everytime I close one of those programs the respective process keeps running in the background.
I can't restart the program until I go to the task manager and kill the process (AfterFX.exe, Adobe Premiere Pro.exe, pproheadless.exe)
I already tried a clean uninstall with the cleaner tool and reinstall but the problem remains.
I encountered this problem few months ago after a longer break from Adobe.
Never had any problems before.
I cloned my complete system with Acronis on a new SSD few months ago..
can't remember anything else with much impact which could have triggered this.
System: Win7 x64
Software: Adobe CC

I found the Solution (for me at least)
It seems to be a driver problem with graphic cards from nvidia's 600 series.
I have installed the oldest available driver for my GTX 680 and everything works fine now (some newer drivers might also work)
I'm gonna write a e-mail to the Nvidia support and tell them what happened, pls do the same if you found the solution due to this post and
upcoming drivers gonna work well for us again.
best regards

Firefox process keeps running after closing

If i close Firefox i cannot reopen it afterwards because the process is still running in the taskbar.
I already disabled all plugins and addons but this didn't work.
I tried to uninstall and reinstall (without deleting personal data) without success.
If i start firefox in safe mode the problem also occures.
If i start firefox with another user on my pc there is no problem.
Anyone an idea?

Once closed, Firefox keeps running in the background and ties up 50% of my CPU at 112mb of memory. WHY?

Just keep following the suggested solution until you die.

Firefox keeps running and will not turn off

Even when not on intrnet firefox keeps running in the background slows everything down and cannot be uninstalled as itis still running

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles. 
NOTE: Establish a habit of exiting/closing Firefox with Firefox button > Exit or File > Exit to allow an orderly shutdown of Firefox and closing of all of the files that Firefox has open.

I recently had to reinstall my software for a
dell computer a dell latitude d 830, then after installing all of my software and such including itunes the player did well even record to disks with no problems now that my system has done alot of updating of system files....now the itunes does not burn to my cd...error message 2131 this time
The 2131 usually indicates firmware needs to be updated on a drive.
Head to your drivers and downloads page for your latitude at Dell, and check for updates to your firmware for your optical drives. If you're behind and you update, does that clear up the 2131?

Firefox process occasionally continues to run after closing browser in XP Pro 64 and uses 50% CPU

Every once in awhile after closing Firefox 3.6.13 the process continues to run. The way I discover this is my CPU temperature monitor is increasing from 36C to 50C, so I open the Task Manger and see that it is using 50% of the CPU, slowing down the computer. I am running XP Professional 64 bit SP2 with all the latest updates on an Intel E8400 3.0GHz overclocked to 3.6GHz and 4GB dual channel DDR2-1066 at 800MHz. This happens only occasionally, maybe once or twice a month. I just end the task and the temperature of the CPU drops and everything is normal again.

Norton IPS is apparently a known issue being mentioned in the KB articles:
*[[firefox will not start]]
* [[firefox crashes when you open it]]
* I also found an earlier post on the Norton site http://community.norton.com/t5/Norton-Internet-Security-Norton/Norton-IPS-1-0-Addon-for-FireFox/m-p/25425#M8494 but I am not sure this is still considered a problem.
What exactly is this IPS extension. I am currently using XPs with Norton's NIS (version 18.6 - it is a paid for subscription). I do have Intrusion Prevention active in NIS but I see no specific extension or program IPS. Is this some optional additional software?
I did find an explanation but from 2009
* http://community.norton.com/t5/Norton-Protection-Blog/Intrusion-Prevention-System-IPS-Your-first-line-of-defense/ba-p/124400
I am NOT using the Norton Toolbar etc. is it these components that are causing the problem i.e safe search etc.
I am not having problems with firefox hanging or continuing, despite using NIS.
There is a bug on this https://bugzilla.mozilla.org/show_bug.cgi?id=548945 but that does not seem to have got very far in confirming or resolving the issue. I imagine Norton have a very large userbase and it seems unlikely that the basic NIS is itself incompatible with Firefox.

Firefox keeps crashing and closing after I've used HP Photosmart software

As title. I'm using Firefox 35.0.1 but the last few versions of FF have done this too.
After I've done any scanning with HP Photosmart scanning software Firefox keeps closing with a send-error-report box if I switch to a different tab or scroll up or down with the mousewheel. It does this almost immediately every time I restart FF and the problem is only solved by rebooting my laptop.
I updated all my drivers including nVidia drivers about ten days ago but it hasn't made a difference and tbh it doesn't seem like a graphics error to me anyway. This problem has gone on for several versions of FF now and I don't really have time to reboot my laptop every time I use my printer :( Maybe it is down to the HP software, but Chrome, Opera and IE don't have this issue, only FF, and using other browsers only serves to remind me how much I really prefer FF over all the others LOL x

Firefox exe continues to run after closing all windows, and consumes massive amounts of cpu

after closing all firefox windows and trying to reopen i get the "firefox is still running but unresponsive" message, and have to go into task manager, processes and end the firefox exe, which is consuming between 96 and 100 cpu.
